--- Pseudo Saturn `Kai' --- WWW : http://ppcenter.free.fr/pskai/ Forum: https://segaxtreme.net/threads/pseudo-saturn-kai-official-thread.24037/ By cafe-alpha ( http://ppcenter.free.fr/devblog/ ). 1. About this firmware ========================================== Pseudo Saturn Kai is a slighltly improved version of Pseudo Saturn firmware. Pseudo Saturn firmware page : http://github.com/cyberwarriorx/pseudosaturn Goal of Pseudo Saturn Kai is to add a set of convenient features for playing Saturn games, and to provide built-in support for some extra cartridges or mods. Features : - Boot CD-R without the need of hardware mod - Play import games - Data transfer with PC - In-game backup memory support directly to cartridge's SD card - Save Data Manager - Image selection support for Rhea/Phoebe ODEs - Cheat Codes - Dezaemon 2 Save Game Manager (DZ2SGM), from SD card or CD-ROM Supported cartridges and/or other mods : - Any boot cartridge with at least 256KB flash memory. Example : Action Replay, Gameshark, etc. - USB dev cart : http://ppcenter.free.fr/satcart/#usb - Gamer's Cartridge : http://ppcenter.free.fr/satcart/#gamers - Rhea/Phoebe : https://gdemu.wordpress.com/ 2. Archive Contents ========================================== Files in root folder : - cdpatch.exe : CD-ROM image patcher utility. - cdpatch_exe_readme.txt : Informations about patcher utility. - flasher.bin : Flasher utility, in bin format (*1) - flasher_bin_readme.txt : Information about flasher.bin. - pskai_alternate_flasher.cue : For use when iso is not directly supported. - pskai_alternate_flasher.iso : Alternate flasher utility. - pskai_sdm_flasher.cue : For use when iso is not directly supported. - pskai_sdm_flasher.iso : Save data manager & flasher utilities. - readme.txt : This file. - SatCom_src_.7z : sources and other development related stuff. (*1) About bin format : Files in .bin format are Saturn raw executable file. Execution address is 0x0600400. Please use file in bin format in the case you want to upload and execute code from your Saturn. You can also use bin format in the case you can load Saturn programs from SD card : Simply copy .bin file to SD card root folder, and execute this file from "Load Homebrew" feature in Pseudo Saturn Kai main menu. 3. Should I need to install Pseudo Saturn Kai ? ========================================== This is a major Pseudo Saturn Kai release, so you probably may want to give a try to it. More than only booting CD-Rs, it also features cheat codes so that you may be interested in Pseudo Saturn Kai even if your Saturn is modded. Please note however that flashing Saturn cartridge may brick it (the risk is small, but not zero), so please upgrade your cartridge after considering the risks and the interests of using latest version : - Please refer to disclaimer section regarding any trouble that may happen when flashing Saturn cartridge. - Please refer to changelog section in order to verify if latest features are worth using or not. (if you're not interested in latest features, then it's probably better to continue using version currently installed) 4. How to install ========================================== There are many ways to install Pseudo Saturn to your cartridge. The most widely used method is the swap trick one, because it works even when performed on a plain (unmodded) Saturn. Note : there are two Pseudo Saturn Kai versions available : - full (first entry in flasher menu) - lite (second entry in flasher menu) Full version is designed for cartridges with the following requirements : - Compatible SD card interface or USB dev cart availability - At least 1MB boot ROM available If your cartridge is not compatible, please install Pseudo Saturn Kai lite. Examples : - Gamer's Cartridge : Pseudo Saturn Kai full (first entry in the list) - USB dev cart : Pseudo Saturn Kai full (first entry in the list) - Action Replay : Pseudo Saturn Kai lite (second entry in the list) 4a. How to install : upgrade from previous version ------------------------------------------ This section describes how to upgrade firmware from a previous version of Pseudo Saturn. In that case, using swap trick method isn't required since flasher utility can be loaded by using Pseudo Saturn currently installed. Requirements : - A cartridge with old version of Pseudo Saturn installed. - "Save data manager & flasher utilities" utility burned on CD-R. Installation steps : 1. Turn your Saturn OFF. 2. Plug cartridge into your Saturn. 3. Insert "Save data manager & flasher utilities" CD-R into your Saturn. File name is pskai_sdm_flasher.iso. 4. Turn your Saturn ON. 5. Load flasher utility by using old version of Pseudo Saturn. From Save Data Manager main menu should display after SEGA logo. 6. Press R shoulder button in order to show sub menu. 7. Select "Firmware Flasher" entry. 8. Select and flash Pseudo Saturn Kai by following instructions displayed on screen. Note 1 : Flash vendor/device IDs are shown at the top of the screen in order to indicate if your cartridge is correctly inserted or not in its slot. Basically, if vendor/device display is green, you have high chances that cartridge erase/flash ends successfully. And if vendor/device display is yellow or red, please slightly move your cartridge in its slot until display becomes green. You can do this "cartridge slightly move" operation when firmware selection menu is displaying. Note : "slighlty" = 1-2mm, nothing more. You don't need to (and shouldn't) remove/insert your cartridge while Saturn is powered on. It's not a NES game cartridge :D Note 2 : Even if the cartridge is displayed as detected, it doesn't guarantee that erase/flash process will end successfully. If erase/write failure happen, please slightly move your cartridge in its slot and retry to flash until "Write Verification Success" is displayed after flashing. 4b. How to install : swap trick method ------------------------------------------ Note : when upgrading from a previous version working of Pseudo Saturn, you don't need to swap your disc : booting Pseudo Saturn Kai Save Data Manager from Pseudo Saturn main menu will do the job. For more informations, please refer to section 4a above. Requirements : - A Saturn cartridge. - One original game, booting correctly on Saturn. - "Pseudo Saturn Kai alternate flasher utility" utility burned on CD-R. First, please try swap trick without cartridge inserted : this is in order to verify your flasher CD-R can be read correctly by your Saturn, and getting some experience about swap trick. In order to learn about swap trick, please watch videos about "sega saturn swap trick" on your favorite video streaming site. After you're OK with swap trick without cartridge, please plug your cartridge, but move it slightly in its connector in order to make Saturn incorrectly detecting it, hence booting from CD-ROM (please try with your original game : if Saturn boots to game, it's OK, if Saturn boots to cartridge boot menu, you need to move the cartridge a little more), and perform the swap trick with your "Pseudo Saturn Kai alternate flasher utility" CD-R as you did above. From firmware flasher main menu, please slightly move your cartridge in its connector in order to make it correctly recognized by flasher (= vendor/device IDs displayed in green color), then select and flash Pseudo Saturn Kai by following instructions displayed on screen. Notes 1 and 2 in section 4a above applies to this way of flashsing too, so please verify everything is allright regarding theses notes. Note : "Firmware Flasher" may not be displayed in Save Data Manager sub menu when cartridge isn't correctly inserted, not working correctly, or when swap trick is not performed correctly. In that case, please please give another in section 4a above try by using pskai_alternate_flasher.iso instead of pskai_sdm_flasher.iso. 4c. How to install : modchip/ODE method ------------------------------------------ 1. Turn your Saturn OFF. 2. Plug your cartridge to your Saturn memory cartridge port. 3. Put CDROM where you burned pskai_sdm_flasher.iso in your Saturn. 4. Turn your Saturn ON and boot from CD-ROM. 5. After main menu appears, press R shoulder button in order to show sub menu. 6. Enter Firmware Flasher item in sub menu. 7. Follow the instructions displayed on Saturn screen. Note : when using ODE, you probably don't need to burn pskai_sdm_flasher.iso to CD-R. Please refer to your ODE user manual about how to execute Saturn iso file from it. 4d. How to install : SD card method ------------------------------------------ This method is designed for Gamer's Cartridge only. It have the advantage of not requiring swap trick method, and also not requiring the usage of any CD-R. 1. Turn your Saturn OFF. 2. Copy flasher.bin file to your SD card root folder. 3. Plug your cartridge+SD card to your Saturn memory cartridge port. 4. Turn your Saturn ON. 5. If quick boot menu is displayed, please press B button in order to display main menu. 6. From Pseudo Saturn Kai main menu, select the following items : "Start Homebrew" -> "SD Card" -> "flasher.bin" 7. Follow the instructions displayed on Saturn screen. 4e. How to install : USB transfer method ------------------------------------------ 1. Turn your Saturn OFF. 2. Connect your USB dev cart to your PC via USB. 3. Plug your USB dev cart to your Saturn memory cartridge port. 4. Turn your Saturn ON. 5. Execute flasher.bin file from PC to Saturn address 0x06004000. 6. Follow the instructions displayed on Saturn screen. 5. Pseudo Saturn Kai features ========================================== 5a. USB dev cart / USB Data Link support ------------------------------------------ When Pseudo Saturn Kai main menu is displayed, it is possible to perform data transfer with the following devices : - USB dev cart - USB Data Link, or any comms link equivalent device : - Freewing - Exstand/Yano - Original Comms Link card Default link type is USB dev cart. Link type can be changed in Settings menu. Please note that since settings data are stored in Saturn internal backup memory, they are reset to default values after changing Saturn's CR2032 battery. Also, there are two variations of the comms link type : EMS and Datel. The most reliable way to see which type your Action Replay cartridge is using is to try one link type, and switch to second one in the case data transfer with first one didn't worked. Note : "Link Diagnostic" feature at the bottom of link type selection menu shows debug message on screen when processing data access request from PC. Usage of this Link Diagnostic feature is recommended when setting up link type. 5b. In-game USB connectivity ------------------------------------------ In-game connectivity with PC is an extra feature available via cheat codes. It supports USB dev cart with SatLink software only. Main features : - Supports only CWX game loader - Cheat cache location code (`B' code) definition not necessary Depends on USB transfer mode used. See below for details. There are several USB transfer modes available, with their own (dis)advantages : 1. "USB + Cheat Codes" mode Description : ROM-based cheat codes handler + USB connectivity enabled Advantages : can perform cheat codes and connectivity simultaneously Disadvantages : may cause slowdowns and/or missing graphics on some games 2. "USB Only (ROM)" mode Description : ROM-based, called directly from first stage interrupt handler Advantages : doesn't uses cheat codes cache memory set in `B' code Disadvantages : a bit slow, but faster than "USB + Cheat Codes" mode 3. "USB Only (RAM)" mode Description : assembly optimized USB handler, running in RAM Advantages : fastest USB connectivity mode Disadvantages : only basic (read/write) commands implemented Note : In order to enhance in-game USB transfer support, all transfer modes above don't use CRC check, hence aren't compatible with latest official version of SatLink or ftx command-line utilities. Typical selection of mode is to select "USB Only (ROM)" mode when cheat codes cache location is not yet set. In that case, master code (starting with `F') needs to be valid, so if not defined it is recommended to try with usual master codes such as F6000914 C305, etc. After a suitable location for cheat codes cache is set, it is then recommended to use "USB Only (RAM)" mode for better compatibility. There's no warranty USB transfer can work for your favorite game. And, support for development cartridges is no longer active, so if you encounter a problem, have a technical question, or want some specific development feature to be added, then ... just solve things by yourself. 5c. USB dev cart DMA transfer support (aka "The Blinking Screen") ------------------------------------------ If you're nostalgic of the USB dev cart old firmware's blinking transfer screen, it's possible to display it by entering "USB DMA transfer" item from main menu. Advantages of using this blinking screen : - DMA is used in USB transfer, hence faster than in firmware main menu. - Blinking screen code and stack fits in 06002000 - 06003FFF address range, hence it is possible to upload data almost everywhere in your Saturn. For example, you can transfer graphics to VDP memory, game level data to low work RAM, and your game executable to high work RAM only by using USB transfer from your dev PC. - It is compatible with old version of SatLink/ftx transfer utilities. Disadvantages of using this blinking screen : - The only way to return to Pseudo Saturn Kai is Saturn system reset. - CD-ROM isn't unlocked, so executing code using CD block may not work. Screen color codes : - Blinking : Idle (waiting for commands from PC). - Orange : Transferring data. - Purple : Unknown command. - Red : Checksum error / Not connected to PC. Notes : - Colors are blinking in yellow -> green -> blue order. - Unknown command (purple) color is displayed for approximately 2 seconds. - Error (red) color is displayed for approximately 2 seconds. 5d. In-Game Soft Reset ------------------------------------------ This feature performs system reset instead of showing multiplayer screen when A+B+C+Start key combo is pressed. This concerns only the transition to multiplayer screen, so other transitions (for example, to main screen, etc) aren't changed. Example : With soft reset disabled : Game -> A+B+C+Start -> Main Screen -> A+B+C+Start -> Multiplayer Screen With soft reset enabled : Game -> A+B+C+Start -> Main Screen -> A+B+C+Start -> System Reset -> Pseudo Saturn Kai Advantage of this feature is to reset the game without having to push console's reset button. If you need to go to multiplayer screen, it is possible to show it from Pseudo Saturn Main Menu with the following operations : 1. Press B button in order to display exit menu. 2. From exit menu, select "Exit to Multiplayer" and confirm with A button. By default, this feature is enabled, and it is possible to disable it when full version of the firmware is used : 1. From Pseudo Saturn Kai main menu, select Settings item, and enter it with A button. 2. Select "Soft Reset" item, and set it to "Multiplayer Screen" with A button. Note #1 : lite version of the firmware doesn't allows to disable this feature, so please let me know if a game compatible in Pseudo Saturn Kai previous version is no longer compatible so that I can see for a workaround. Note #2 : idea about this feature is from neuroacid, who first implemented it in rmenu utility. 5e. Internal Save Data Autodump ------------------------------------------ This feature is only available in full version of the firmware. This feature allows to dump news saves from Saturn internal backup memory to SD card. Saves are dumped into SAVES -> AUTODUMP folder, in .BUP format. Interest of this feature is to keep save data stored in internal backup memory even after changing Saturn's CR2032 battery. It is possible to restore the autodumped saves with the following operations : 1. From Pseudo Saturn Kai main menu, enter "Save Data Manager" with A button. 2. From Save Data Manager main menu, select "Save Data Import". 3. From file selection browser, select "AUTODUMP" folder, then the first save in this folder. 4. From save data selection menu, select the saves you want to restore and confirm with A button. (Multiple selection can be done with X button and all saves can be selected with Y button) 5. From device selection menu, select "Internal Storage" and confirm with A button. Note : changing CR2032 battery while Saturn is powered on shouldn't damage it, and doesn't wipes save data from internal backup memory. Don't hesitate to use this trick if you're using lite version of the firmware. 5f. Virtual FDD ------------------------------------------ This feature is only available in full version of the firmware. This feature allows to simulate Saturn Floppy Disk Drive (FDD) in the same way Virtual Memory Cartridge features simulates cartridge on SD card. Virtual FDD is enabled automatically when Virtual Memory Cart is enabled. Please let me know if that causes problem. Limitation : up to 10 saves per partition are supported. Please let me know if this is not convenient for a specific game using FDD. RAM usage when virtual memory cart and virtual FDD are running is quite tight (24KB in two non-contiguous buffers) memory, so raising this maximum count to a larger value may not be possible. 5g. Memory Cartridge via USB dev cart ------------------------------------------ This feature is only available in full version of the firmware. It is possible to provide memory cartridge support on PC via USB dev cart. Requirements : - USB dev cart with Pseudo Saturn Kai full version installed This requires at least 1MB flash ROM available on cartridge : - Carts with SST39SF010A flash chips (128KB per chip, total 256KB) aren't supported. This concerns few cartridges assembled just after USB dev cart release around 2012-2013. - Carts with SST39SF040 flash chips (512KB per chip, total 1MB) are supported. - PC running SatLink software How to enable Memory Cartridge via USB dev cart : 1. Plug cartridge, insert game CD-ROM 2. Power on Saturn 3. Run SatLink software, and enable USB dev cart transfer 4. Click "Show Log Output" on SatLink title bar 5. Select "Start Game" It is necessary to keep SatLink showing log output window while game is running. Also, game may show some glitches while accessing virtual memory cartridge files on PC. Reasons about this are unclear, and there are no plans to fix this. There's no warranty USB Memory Cartridge can work for your favorite game. And, support for development cartridges is no longer active, so if you encounter a problem, have a technical question, or want some specific feature to be added, then ... just solve things by yourself. 5h. Exception Handler Screen (aka BSOD) ------------------------------------------ This feature is enabled by default and shows a "Blue Screen Of Death" screen when program encounters an exception. Main features : - Show register dump where exception occured. - Allow system reset from pad's Start button. - Allow USB transfer when USB dev cart is used. 5i. Cheat Codes ------------------------------------------ This feature allows to execute cheat codes. Main features : - In-RAM (fast) cheat codes handler. - Many built-in codes. - Automatic game selection. Features available in debug version only : - In-game USB transfer : only USB dev cart supported. - Custom cheat code input. Features not available : - Cheat code addition to built-in list. This requires full re-compile of firmware, hence won't be added. - Custom cheat codes and settings save to internal backup memory. This may be added in a future release. 5j. Rhea/Phoebe ODE support ------------------------------------------ Rhea and Phoebe ODEs are supported natively in Pseudo Saturn Kai. The main purpose of this feature is to allow image selection and cheat codes selection in respectively two menus, without any system reset, extra setup menu and/or any other magical spell between them. Main features : - Compatibility with list generated for Rmenu - Images list sorting - Record of last selected image 5x. Minor Tricks / Trivia ------------------------------------------ There are several kinds of minor tricks here and there in Pseudo Saturn Kai and Save Data Manager. Theses were basically added for extra testing and/or debug purpose. For example, did you knew that : - Pushing some keys during Save Data Manager main menu enables an extra menu ? - Pushing one shoulder key and 3 other keys when running full version of the firmware shows some kind of mysterious debug utility ? - An easter egg can be triggered from firmware's main menu ?! - Full version of the firmware provides some pre-recorded save data directly from cartridge ROM ? Theses can be used by selecting "RomFs" media when using "Save Data Manager" -> "Save Data Import" feature. - Pushing a some specific keys during credits page will speed up the display ? - X+Y+Z+Start key shortcut from any menu does a system reset ? - Pink (#FF00FF) can be used as transparent color in custom background images ? 5z. Unfinished features / TODO list ------------------------------------------ The features below are not finished, but may be added in a future release. The list below is basically a memo for future myself. - More debug functionality for developers. -> UBC based step by step assembly debugger. - Test of 1MB expansion RAM at faster access speed than default ones. - Save data export to Yabause format in Save Data Manager. - Virtual Memory Cart support with JHL loader and BIOS memory manager. - This readme. 6. Pseudo Saturn patcher utility ========================================== 6a. Purpose ------------------------------------------ Pseudo Saturn patcher utility makes games working correctly with JHL loader. For the majority of Saturn games, copying original game to CD-R without the need of patching things in the meanwhile will do the job, but for some reasons few games won't work correctly if not patched. 6b. Games Requiring Patching ------------------------------------------ - Alien Trilogy - Assault Rigs - Batman Forever The Arcade Game - Center Ring Boxing - Destruction Derby - Discworld II - DJ Wars - FIFA Rumbo al Mundial 98 - Genso Suikoken - Machine Head - Mechwarrior 2 - Mortal Kombat II - NBA Jam Extreme - NBA Jam Tournament Edition - NBA Live 97 - NBA Live 98 - NHL Powerplay '96 - Panzer Dragoon Azel/Saga - Scud - The Disposable Assassin - Skeleton Warriors - Terry Pratchett's Discworld - Warcraft II - The Dark Saga - WipEout Note : full list of games requiring patching can be found in Pseudo Saturn Kai compatibility page : http://ppcenter.free.fr/pskai/compat/ Only games listed as requiring usage of patcher utility are concerned. Note : patching is not required when an ODE is used : the reason is that ODE "shows" disc image as an original game CD-ROM, and that patching is required to fool Saturn copy protection when using a CD-ROM backup. 6c. Patcher Utility Usage ------------------------------------------ 1. Double-click cdpatch.exe. 2. Click "Browse" button and select disc image file to patch. 3. Click "Patch" button. Note : iso, cue+bin, mdf, img image file formats are supported. Note : patcher utility works on Windows platform only. If you want to port this utility to your favorite platform, please refer to the sources and do the porting job by yourself. Path to the sources : SatCom_src_.7z -> pseudosat_kai -> cdpatch 6d. Patcher Utility Changelog ------------------------------------------ 2019/05/21, Ver 1.0.0.4 : - Extended support to cue sheets starting with CATALOG keyword. (This command was found on some rips such as Destruction Derby) 2018/02/21, Ver 1.0.0.3 : - Fixed incorrect path setting when selecting cue files. Only .bin image files located on same directory as patcher utility could be patched in previous version. 2016/07/14, Ver 1.0.0.2 : - Added region patching feature. (not needed when using Pseudo Saturn Kai) 7. Save Data Manager features ========================================== 7a. How to Run Save Data Manager ------------------------------------------ Lite firmware users : use pskai_sdm_flasher.iso . Full firmware users : select "Save Data Manager" from cartridge main menu. 7b. Base operations : copy, move, delete ------------------------------------------ Basic operations regarding save data are available in Save Data Manager. Theses operations are similar to the ones provided by Saturn BIOS and also support natively Floppy Disk Drive so that its operation CD-ROM is not required. 7c. Save Data Dump ------------------------------------------ It is possible to dump save data from Saturn or backup memory devices such as cartridge or Floppy Disk to PC or SD card. Supported output devices : - USB Data Link connected to PC - USB dev cart connected to PC - Gamer's Cartridge SD card More than directly copying save data from backup device to output device, it is also possible to temporarily copy a portion of external backup device (cartridge or Floppy Disk) to Saturn internal backup memory and then copy it from Saturn internal memory to PC or SD card. This supports dumping portion of source device as well as data compression when copying to Saturn internal backup memory such as dump of large source data so that whole backup memory cartridge or cartridge ROM can be possible without requiring the usage of invasive dump methods such as ROM chip desolder and then dump with dedicated hardware. 7d. Indirect Dump ------------------------------------------ (1) Introduction to Indirect Dump feature : Indirect Dump allows to dump cartridge boot ROM or backup memory cartridge ROM to Gamer's Cartridge SD card. It can dump saves from backup memory cartridge (such as official ones), or ROM contents of boot cartridge (such as Action Replay, etc). It uses Saturn internal backup memory as a temporary storage for data to dump which is then copied to Gamer's Cartridge SD card, hence the "indirect" naming of this feature. Why using internal backup memory ? Because swpapping Saturn cartridge must be done when Saturn is powered off (hotswapping Saturn cartridge is dangerous : it may damage Saturn, or cartridge, or both, please don't try it), hence temporarily storing data to dump in a non-volatile memory such as internal backup memory is required for dump operation. In comparison to ROM size of cartridge to dump (usually 256KB), internal backup memory is small (32KB), so what's the magic in order to dump a cartridge ? Well, nothing really special : cartridge is dumped into several blocks. When a block is written to internal backup memory then it is required to change cartridge from the one to dump to Gamer's Cartridge, and after the block data is copied from internal backup memory to SD card, then it is possible to continue dump from the end of previous block and so on. Additionally, block data is compressed, so that dump of typical ROM cartridge is usually done in around 5 or 6 passes, vs 9 passes without usage of compression. This may also significantly help the dump of save data : as an example, Sega Rally ghost data stores driver input data without using any kind of compression, which gives very good compression rate during indirect dump. As an option, it is also possible to use Saturn FDD instead of Saturn internal backup memory. In that case, compressed block size is extended to 256KB, so that typical cartridge is dumped in one pass. Advantages of this feature : - It doesn't requires to open nor desolder chips of the cartridge to dump. - It doesn't requires any special electronic equipment such as ROM dumper. Disadvantages of this feature : - It requires to boot Saturn CD-R, hence needs some experience regarding swap trick method when Saturn is not hard-modded. - It may take some long time : typically around 1-2 hours for dumping a backup memory cartridge full of various save data. (2) Requirements : - (A cartridge to dump) - A Gamer's Cartridge and a SD card. - A Saturn able to play CD-Rs, or being able to do CD swap trick. - If required, a new CR2032 battery installed Saturn side. - Pseudo Saturn Kai Save Data Manager utility (pskai_sdm_flasher.iso), burned on CD-R, or copied to your favorite Saturn disk drive emulator. - Optionally, a Saturn Floppy Disk Drive : when detected, floppy disk's second partition is used instead of Saturn internal backup memory. (3) Indirect Dump procedure steps : Before dumping the cartridge ROM, it is recommended to backup the saves stored in Saturn's internal backup memory. This is optional, but since Indirect Dump feature will wipe all data from internal backup memory, you probably want to backup them to continue playing your favorite game(s) after that. Internal backup memory backup steps : 1. Turn off Saturn, plug Gamer's Cartridge 2. From boot menu, select : "Save Data Manager" -> "Save Data Dump" -> "Dump Saturn Backup RAM" -> "SDcard" Saves from internal memory are dumped to the following location : SD card -> SAVES -> today's date (YYYYMMDD) -> BRAM_.BIN Example : /SAVES/20170527/BRAM_001.BIN After indirect dump, it is then possible to restore internal backup memory to original state by using Save Data Manager -> Save Data Import feature. Indirect dump steps : 1. Turn off Saturn, plug the cartridge to dump, and insert Save Data Manager CD-R. 2. Turn on Saturn and run Save Data Manager from CD-R. When dumping a boot cartridge (Action Replay, etc), Saturn should boot from this cartridge. If that's not the case, it is necessary to adjust cartridge's insertion in cartridge slot until Saturn boots from cartridge. 3. From Save Data Manager, select "Save Data Dump" and the appropriate action for the type of cartridge to dump. Examples : - Boot cartridge : "Dump Cartridge Boot ROM". - Official memory cartridge : "Dump Cartridge Backup RAM". 4. From "Dump Size Selection" menu, select "Detected Size". 5. Two confirmation screens should be displayed : first one about confirmation to start indirect dump, and second one about the fact that data on internal backup memory will be erased : please confirm both screens with Start button. 6. After that, Saturn will compress ROM data from cartridge to dump into internal backup memory. Please wait until "Dump data compression success !" is displayed. 7. Turn off your Saturn. 8. Change cartridge from the one to dump to Gamer's Cartridge. 9. Turn on Saturn and run Save Data Manager from CD-R. Note #1 : Since Gamer's Cartridge is used, it is not required to do swap trick, but only to load the CD-R as when loading a game copy. Note #2 : In order to dump the cartridge, it is required to disable Virtual Memory Cartridge when booting Save Data Manager. 10. From Save Data Manager, select "Save Data Dump". 11. Select "Continue" from "Indirect Dump" menu. 12. Select where to store dump data : "SDcard". 13. ROM data will then be decompressed from internal backup memory to SD card : please wait until "Block successfully compressed." or "Cartridge dump completed !" message is displayed. If "Block successfully compressed" is displayed, then some data to dump is remaining, hence please return to step 1 in order to dump remaining data. If "Cartridge dump completed !" is displayed, then all data from cartridge is succesfully dumped to SD card. Dump data is located at the following location : SD card -> SAVES -> today's date (YYYYMMDD) + ID -> CARTDUMP.BIN Example : /SAVES/20170527_001/CARTDUMP.BIN Additionally, dump report is stored into CARTDUMP.TXT file. It contains dump related informations such as dump start address, CRC value etc, and should be kept with CARTDUMP.BIN to prove that ROM was correctly dumped. (4) Advanced features : Some extra features are implemented, and may be available only when USB dev cart is used. Theses are typically for my (cafe-alpha) personal use and/or for helping someone to dump their cartridge. - Dump to PC : This saves dump file to PC (PC-link media) instead of SD card. It is enabled when USB dev cart (or when Action Replay and USB Data Link) is connected and SatLink software is used. - Indirect Dump recovery : This reads indirect dump raw file from PC-link, in the case it can't be decompressed on end-user side. It requires USB dev cart (or modified version of yabause) and SatLink software. I officially don't support all of theses tools. Note : it requires dump header and compressed save data located at the root of PC-link media. - Saturn internal backup memory dumps : it writes internal backup memory raw contents to SD card before decompressing dump data from it. Raw dump files are located in same folder as indirect dump one, under the following names : B_BRAM.BIN and B_BRAM.HDR. Additionally, any eventual error code when writing compressed dump data to internal backup memory is logged into indirect dump report. Because it isn't directly mapped in Saturn memory, this feature is disabled when using Saturn Floppy Disk. 7d. Save Data Import ------------------------------------------ It is possible to import pre-recorded save data from file device connected to Saturn to backup device such as Saturn internal memory, cartridge or FDD. Save Data Manager contains many pre-recorded save data, and contribution of your own save data for your favorite games are welcome. Note when using Gamer's Cartridge : it is possible to import save data from data copied on SD card. For more informations, refer to "SD card setup" section. 8. USB dev cart related informations ========================================== 8a. Setup when using Windows ------------------------------------------ USB dev cart was reported working on the following Windows version : - Windows XP - Windows 7 32/64 bits Please install driver and transfer utility according to setup instructions below: - Power off your Saturn. - Plug your USB dev cart into your Saturn memory cartridge port. - Connect your USB dev cart to your PC via USB. - Turn your Saturn ON. -> Pseudo Saturn Kai main menu appears on Saturn. -> If connected for the first time, Windows is searching for drivers over the internet and installs the USB Serial Port driver. - Execute the libusb filter driver from the following location : -> "USB_dev_cart" folder -> "Driver" folder -> "[REF]" folder -> libusb-win32-devel-filter-1.2.6.0.exe - Click "Next" button. - Read and if OK, accept the software agreement, then click "Next" button. - In "Select Destination Location" window, click "Next" button. - In "Information" window, click "Next" button. - In "Select Start Menu Folder" window, click "Next" button. - In "Ready to Install" window, click "Install" button. - Check "Launch filter install wizard", then click "Finish" button. - Check "Install a device filter", then click "Next" button. - Select USB dev cart's FTDI device, then click "Install" button. -> Vendor ID (vid) : 0403 -> Product ID (pid) : 0601 -> Description : "USB Serial Converter" -> Manufacturer: FTDI - In "Install Device Driver" window, click "OK" button. If USB Serial Converter (FTDI Manufacturer) is not listed in filter installer window anymore, driver installation is completed. - Test the connection with SatLink.exe : -> SatLink.exe - In "Download/Upload" tab, select "usb_dev_cart.ini" as INI file location. - Click "OPEN" button. - Select "Start Address" as 0x06004000. - Check everything in "Exec Parameters" frame. - In "Upload/Execute" frame, select flatcube.bin : -> "USB_dev_cart" folder -> "link_test" folder -> flatcube.bin - Click "Execute" button. If you see a 3D rotating cube on your TV screen, your USB dev cart works correctly. If you prefer setup manual with screenshots, please use the (a little old) manual from the following location : -> "USB_dev_cart folder" -> SEGA_Saturn_USB_devcard_Win7_64.pdf Note #1 : this manual refers to a relatively old version of SatLink. Please use the latest version of SatLink from my homepage : http://ppcenter.free.fr/satcom/ Note #2 : - SEGA_Saturn_USB_devcard_Win7_64.pdf was made by Duranik team. - flatcube.bin was made Mic : http://jiggawatt.org/badc0de/console.htm 8b. Setup when using Linux ------------------------------------------ When using antime's ftx utility, some USB dev cart commands are not compatible with Pseudo Saturn Kai, especially -x (execute) one. Hence, it is recommended to use slightly modified ftx available from the following location : -> "USB_dev_cart" folder -> ftx folder ftx was reported working on at least one Linux configuration. I don't know if it will work on yours. 9. SD card related informations ========================================== 9a. SD card interface(s) support ------------------------------------------ Pseudo Saturn Kai currently supports the following SD card interface(s) : - Gamer's Cartridge More SD card interface(s) may be supported in future releases. 9b. SD card requirements ------------------------------------------ Virtual Memory Cartridge feature doesn't requires large storage capacity, hence large (expensive) SD card is not indispensable. - Capacity : 4GB or more - SD card type : SD or SDHC (SDXC support is not tested) - Supported partition scheme is "Master Boot Record". "GUID Partition Table" or anything else won't work. - File system : FAT32 (not FAT, not exFAT, not NTFS, not anything else) 9c. SD card setup ------------------------------------------ Format SD card by with the following settings : - Partition scheme : Master Boot Record - File system : FAT32 - Allocation size (cluster size) : default allocation size. //vvvvvvv Will be available in a future revision of Pseudo Saturn Kai vvvvvvv // Optional setup step : copy pskai_sdm_flasher.iso to your SD card's root folder. // This allows to : // - Import save data from this iso file to Saturn internal backup memory or // Gamer's Cartridge backup memory. // - Enable Dezaemon 2 Save Data Manager usage from SD card. // Theses features are available from Save Data Manager CDROM, but copying iso file // to SD card makes theses features above available without having to swap between // game CD-ROM and Save Data Manager CDROM. //^^^^^^^ Will be available in a future revision of Pseudo Saturn Kai ^^^^^^^ The feature above is under development and shall be available in a future revision of Pseudo Saturn Kai. Instead, please copy all files in DEZA2 and SAVES folders from Dezaemon Save Game Manager iso to SD card under the folder organisation described below : [SD card] |-DEZA2 (folder) | |-DZ2SGM.LZF | |-SGM_THB.RAW | |-DATA (folder) | | ... | |-SGM1 (folder) | | ... | |-SGM2 (folder) | | ... | |-SGM3 (folder) | | ... |-SAVES (folder) | |-(many sub folders) | | |-(save data files) 9d. SD card file write optimization tricks ------------------------------------------ - Class 10 (or better) SD card. - Clean formatted SD card will give best write performance. - Less files/folders as possible in root folder : If you want to store Pseudo Saturn Kai unrelated files and folders in your SD card, it is recommended to move theses from root folder to a sub folder. This also slightly improves file read performances. - The smaller SD card capacity, the better. There's no need however to use old 2GB non-SDHC card, which are quite expensive. Instead, a cheap SDHC card is usually a better choice. - The larger FAT32 cluster size, the better. 10. Cheat codes related informations ========================================== 10a. How to enable cheat codes ------------------------------------------ Cheat codes can be enabled from loader selection menu : - Select loader with X button : use cheat codes - Select loader with A/C/Start button : don't use cheat codes Note : cheat codes can't be used with JHL loader. When using cheat codes, CD-ROM is loaded, and according to game title the following menus are shown : - Game selection menu : game in CD lid is likely not being supported. Please manually look for game in list in the case association for automatic search is incorrect. - Cheats selection menu : game is automatically selected, and the last step before loading game is to choose which cheat(s) to enable. Note : it is possible to select multiple cheats with X button. 10x. Some technical information ------------------------------------------ This is technical information not necessary for normal usage. Basically, this is just a memo when I (cafe-alpha) want to verify something about cheat codes but don't have enough time to dig into source code to find the information. There are two types of cheat codes handler : - ROM based handler : cartridge ROM is used for both cheat codes handler and address/value pairs for each cheat codes enabled. RAM is used for only for cheat codes interrupt handler and to specify which codes are enabled so that this type is convenient for games where unused RAM areas are scarce and/or little. An other advantage of this cheat handler type is that it allows in-game connectivity with PC via USB dev cart. On the other hand, execution is quite slow, so graphical glitches may happen on some games. - In-RAM handler : cheat codes handler, settings and address/value pairs are put in RAM. This have the advantage of being fast so that most games are compatible with this type of handler. Finding enough unused RAM for this type of handler may sometimes not be possible, and additionally it doesn't allows usage of USB connectivity. If both fast execution and USB connectivity are required, then using "USB only RAM handler" is recommended. As the name suggests, it doesn't allows usage of cheat codes, so this is just for development purpose. About memory organisation regarding cheat codes : 1. Cheat codes cache : it contains few cheat codes setting and first stage bootloader. It redirects to cheat codes handler which can be located either in cartridge ROM or RAM according to handler type in use. 2. Cheat codes handler : small executable which applies user-enabled cheat codes. Additionally it also may support in-game connectivity with USB dev cart. 3. Codes cache : table in ROM indicating all address/value pairs for each cheats. ROM based handler directly uses this table while in-RAM handler uses address/value pairs copied from this table to RAM. About memory usage regarding cheat codes : - First stage bootloader : 0x40 bytes Contains interrupt handler, opcode for master code and few settings. - In-RAM handler : 0x60 bytes That's the space for maximum 48 SH2 instructions. - Codes cache : 8 bytes per code Address : 4 bytes, value : 2 bytes, command : 1 byte. Remaining byte is unused. 10y. Notes about cheat code setup ------------------------------------------ Features in this section are available in Pseudo Saturn Kai debug version only. When setting up new cheat code, it is necessary to setup master code first, which is composed with : - Patch code, starting with `F' - Location code, starting with `B' First, it is recommended to look for appropriate location code. Simplest way to setup location code is to try default locations below : - 0x060FF000 : cheat codes cache is located at the end of high work RAM. 0x1000 (4096) bytes available for handler and codes cache, which allows a maximum of 492 codes with in-RAM handler. - 0x06002800 : cheat codes cache is located on IP header's SEGA logo bitmap. Using this locations breaks Sega logo display on game startup, but except that point game should boot normally. 1352 bytes available for handler and codes cache, which allows a maximum of 157 codes in-RAM handler. Even more maniac tricks : - Look for unused RAM with "0xA5 HRAM fill" feature and then "BSOD on soft reset" feature. So far, this trick didn't worked correctly however ... - Use buffer from backup library : a part of it seems not used by BUP library. This is a last chance solution, since area there is small, and also because there's no waranty that the game doesn't uses this buffer for other things when not using backup library. 11. Rhea/Phoebe ODE support ========================================== 11a. Overview ------------------------------------------ Rhea and Phoebe are Optical Disc Emulators (ODE, a modern replacement for CD-ROM drive), which uses SD card to store CD image to show to Saturn. More informations about Rhea/Phoebe is available at the following page : https://gdemu.wordpress.com/about Rhea/Phoebe SD card can contain several disc images, and selection of which one to show to Saturn is done via a Saturn application called Rmenu. In order to make the usage of Pseudo Saturn Kai features user-friendly, the configuration job normally done on Rmenu is available on Pseudo Saturn Kai side, thus allowing image selection and cheat codes setting in a couple of menus. 11b. Requirements ------------------------------------------ Correct installation and configuration of Rhea or Phoebe ODE is required. Installation steps for Rhea : -> https://gdemu.wordpress.com/installation/rhea-installation/ Installation steps for Phoebe : -> https://gdemu.wordpress.com/installation/phoebe-installation/ This requires some screws to remove, few wires to connect, and eventually some few basic soldering skills. In case of technical question, please refer to the place where you bought your ODE from. Then, Rhea or Phoebe require at least firmware version 3.5.0 (for Rhea) or 3.2.0 (for Phoebe) in order to get image selection menu being supported. If not already done, please retrieve latest firmware from the following link : -> https://gdemu.wordpress.com/firmware/ And then follow the update steps detailed on the page to update your ODE to latest firmware version. Both lite and full versions of Pseudo Saturn Kai firmware supports ODE image selection, so a regular Action Replay cartridge is enough to enjoy both cheat codes and Rhea/Phoebe ODE. But if you want to use both cheat codes and save data not fitting into Saturn internal backup memory, please note that hotswapping between Action Replay and official memory cartridge is dangerous : it may damage Saturn, or cartridge, or both, so please don't try it. In that case, using a Gamer's Cartridge is recommended. This concerns very specific games such as racing games (for race ghost data), Dezaemon 2 (DIY shooting game) or RPGs. So using Action Replay should be enough for typical gaming requirements. 11c. Image selection menu limitations ------------------------------------------ Image selection menu is designed with the following limitations, which shouldn't cause major problems, but listed here for reference : - List file (LIST.INI) maximum size : 800 KB - Maximum folders count : 2500 folders - Maximum length per image title : 128 characters 11d. Setup ------------------------------------------ Image selection menu requires Rmenu iso to be set in folder 01 of the SD card used by Rhea/Phoebe. This iso file contains a list of disc images available in the SD card and is generated with a PC application called RMENU.exe. For more details, please refer to the Rmenu readme, and follow the setup steps detailed there. After setting up Rmenu, it is necessary to indicate to Pseudo Saturn Kai that Rhea/Phoebe ODE is available. This can be done in Settings menu, reachable by pushing B button from Pseudo Saturn Kai loader selection menu, and then by setting "Optical Disc" value to "Rhea/Phoebe". 11e. How to Use ------------------------------------------ After setting up optical disc to "Rhea/Phoebe", the game start menu is changed into disc image selection menu, with the following keys mapping : - X : enable cheat codes - Y : change list sort settings - Z : game loader manual settings - L/R : show settings menu - Arrows : select disc image - A/C/Start : load selected disc image 11f. Image Selection Setting Menu ------------------------------------------ Settings menu is available by pushing L or R button from image selection menu. From there, it is possible to verify ODE firmware version and tune the some miscellaneous settings such as image sorting, - Name Prettify : force lowercase of letters inside a word. This is useful for displaying list containing titles directly from image header, since theses are written only with CAPS letters. If your images list was hand-modifed during rmenu iso generation, then this setting should be set to OFF. - Image Sort : select how to sort disc image list. List can be sorted by folder ID, or release date, or disc title. - List Order : select to display list in ascending or descending order. - Display Type : select "monospace" or "proportional" type to show disc image selection menu. Monospace type displays disc image list with 8x8 pixels fixed font while "proportional" type uses variable width font, hence allowing more information to be displayed on screen. If you want all characters to be vertically aligned, then "monospace" is the recommended choice, else "proportional" may be preferred. - Text Justify : select to display image titles left-justfied or centered. - Color Theme : select the color theme to display image selection menu. - Load Rmenu : load rmenu utility. This loads the image stored in the first folder of SD card for Rhea/Phoebe. - Compatibility Report : enable compatibility reporter and load previously selected image. Note : this is available only when a cartridge with supported SD card interface (example : Gamer's Cartridge) is detected. Note : it is also possible to enable compatibility reporter from image selection menu by to pushing Z button (manual setting) and then Y button (enable compatibility report). 12. F.A.Q. ========================================== Q1. I want XYZ feature for ABC hardware implemented right now !!! A1. No problem : sources are available in SRC folder of flasher utility CDROM, so please get the things done by yourself. You may prefer Pseudo Saturn sources as a simple starting point since theses can be compiled easily with CMake. Pseudo Saturn Repository : http://github.com/cyberwarriorx/pseudosaturn Q2. I would like to report a bug/improvement/feature request/whatever ... what should I do ? A2. Please send me (cafe-alpha) *DETAILED* informations about what you would like to be improved/modified/etc. Pictures explaining what you want to do are welcome. Please note that Pseudo Saturn Kai is a homebrew application made on my (cafe-alpha) free time and good mood, so I don't guarantee anything about past and future bug fixes, feature requests, releases, etc. Q3. Can you fix a non-working cheat code and/or adding a specific cheat code for my favorite game ? A3. This depends on my free time and motivation, and because of limited flash ROM size, there is a limitation regarding quantity of cheat codes that can be added to Pseudo Saturn Kai too. Whatever it may be, please report bugs or requests on Segaxtreme forums, which is more convenient than directly contacting me. -> https://segaxtreme.net/threads/pseudo-saturn-kai-official-thread.24037/ Q4. Are there online resources about Pseudo Saturn Kai ? A4. Yes. Please check there for latest version from official page : - http://ppcenter.free.fr/pskai/ Game compatibility list : - http://ppcenter.free.fr/pskai/compat/ Thread on Segaxtreme forums. Please use it for feature requests, bug reports, or game incompatibility reports. - https://segaxtreme.net/threads/pseudo-saturn-kai-official-thread.24037/ I prefer thread rather than email when dealing about requests, bugs or reports, since it sometimes requires everybody's point of view in order to be solved. I also use this thread in order to write latest informations about development and F.A.Q., instructions, etc. Q5. I made some changes to the firmware sources. Do you have some github, SVN, or anything else collaborative thing so that I can contribute to your sources ? A5. I don't have plans to do collaborative development regarding Pseudo Saturn Kai, because this won't longer be a funny project when several people would be deciding about deadlines, development goals, etc. So if you want to push your changes into my sources, please contact me from the link below, and I may gladly update my sources with your changes. Contact page : http://ppcenter.free.fr/contact/ Please however note that it doesn't guarantee your changes will be merged : I may decide to discard them (if not relevant, or not working, etc), or simply won't do it because of being busy with other things. Q6. "Firmware verification error" is displayed when trying to install Pseudo Saturn Kai ! What should I do ? A6. First, please take a deep breath, and *DON'T* reset your Saturn, because at that time cartridge is potentially bricked, hence may not boot correctly after that. Instead, it is better to push Start button, and then select "Restart Flasher" menu item. Then, adjusting cartridge position in its slot (for example, lifting it by less than 1mm while verifying that cartridge IDs displayed on screen are correct) and retrying flashing operation will give a second chance to your cartridge. There's no guarantee it can fix installation on your cartridge : if problems comes from dying flash chips, then reflashing them won't help a lot. And please install Pseudo Saturn Kai at your own risks ! Q7. Can I install Pseudo Saturn Kai on official memory cartridge ? A7. No : only boot cartridges (Action Replay, Memory Card Plus, Game Shark, and their clones) are compatible with Pseudo Saturn. Official memory cartridges have their ROM located at a different location, and consequently don't allow to boot any firmware. 13. Flasher utility testing status ========================================== Following users could successfully upgrade their Action Replay cartridges with specified vendor/device IDs. Thanks to them for the help in testing ! - cafe-alpha : BFBF/0707 SST29EE010 (Flasher v3.745) - TabajaraLabs : 0101/2020 AM29F010 (Flasher v3.745) - A Murder of Crows : 53BF/4707 counterfeit+SST29EE010 chips ?

(Special thanks to privateye !) - Removed self test feature, which saves 5KB on ROM side to add new cheat codes in the future. 2019/10/27 (Pseudo Saturn Kai, V6.317) : - Fixed automatic loader settings for Mizubaku Daibouken. - In Save Data Manager, discard folder from scan when importing "single type" (such as SSF, PlanetWeb, etc) backup data. - Experimental fix around current time acquisition. (It is for example used to generate folder name when dumping save data to SD card) - Minor fixes in flasher's old firmwares list. - Fixed cheat codes module version display in custom codes loader menu. - More fixes and improvements in autoset list. 2019/09/23 (Pseudo Saturn Kai, V6.315) : - Fixed automatic loader settings for Pebble Beach Golf Links. 2019/05/30 (Pseudo Saturn Kai, V6.314 -- RC1) : - Extra fixes and improvements in autoset and cheat codes list. 2019/05/26 (Pseudo Saturn Kai, V6.313) : - Improved more autoset list regarding games not requiring JHL loader. 2019/05/24 (Pseudo Saturn Kai, V6.312) : - Removed no longer used code in SMPC interfacing module. 2019/05/16 (Pseudo Saturn Kai, V6.309) : - Another experimental fix regarding glitchy display when scrolling menus. 2019/05/07 (Pseudo Saturn Kai, V6.306) : - Fixed pad acquisition stop after CD-ROM related error happens. - Experimental fix regarding glitchy display when scrolling menus. 2019/05/07 (Pseudo Saturn Kai, V6.305) : - Fixed file browser exit shortcut (Z button) during empty folder listing. - Improved autoset list regarding a couple of games not requiring JHL loader. 2019/05/03 (Pseudo Saturn Kai, V6.304) : - Moved SMPC test screen to Save Data Manager's extra menu. 2019/05/01 (Pseudo Saturn Kai, V6.303) : - Additional change around SMPC handling regarding wireless pad support. (Special thanks to vbt for providing technical help !) - Added easter egg ?! Still not finished however. 2019/04/26 (Pseudo Saturn Kai, V6.301) : - Removed attempt to properly retrieve pad initial status when using interrupt-based acquistion mode. - Removed key shortcuts during Pseudo Saturn Kai and Save Data Manager startup. (Theses were about enabling debug features, hence shouldn't be a great loss) 2019/04/25 (Pseudo Saturn Kai, V6.300) : - Candidate fix for wireless pad support : use interrupt instead of INTBACK polling to retrieve pad status -> reported not working correctly. - Disabled SMPC test screen. 2019/04/23 (Pseudo Saturn Kai, V6.299) : - Minor improvement regarding processing of peripheral data from SMPC. - Extra fixes in cheat codes list. - (SMPC test screen is still enabled in this version) 2019/04/22 (Pseudo Saturn Kai, V6.298) : - Added key shortcuts to enable/disable SMPC test screen : -> L+R+Up : enable test menu -> L+R+Down : disable test menu 2019/04/21 (Pseudo Saturn Kai, V6.297) : - Added test menu for verifying SMPC and Pseudo Saturn internals when using wireless pad. This test menu is displayed on startup and without any way to exit so as a consequence it's not possible to use Pseudo Saturn Kai itself. 2019/04/18 (Pseudo Saturn Kai, V6.296) : - Completed (nearly) all associations between games and cheat codes lists. Special thanks to privateye for this huge contribution ! - Improved autoset list a bit more regarding vmem and Saturn FDD support. - When using Rhea/Phoebe ODE, restrict cancel of cheat codes game selection menu to continue booting game anyway. This is due to a lack of clean CD Block reset on Pseudo Saturn Kai, making impossible to return to images selection menu at that time. When using optical disc drive, cancelling cheat codes game selection still returns back to loader selection menu, thus allowing inserting another disc. 2019/04/12 (Pseudo Saturn Kai, V6.292) : - Removed interrupt masking (added in previous beta version) virtual memory cartridge because it causes more harm than improving game comatibility. - Improved autoset list and fixed cheat codes list. (Thank you privateye !) 2019/03/06 (Pseudo Saturn Kai, V6.289) : - Improved stack memory usage by virtual memory cartridge. - In Save Data Manager, added a debug feature to verify stack memory usage by backup library. - Improved performances regarding log messages formatting. - Minor fixes regarding "save logs to SD card" feature. 2019/01/18 (Pseudo Saturn Kai, V6.280) : - Moved CD Block reset timing from software reset patch to Rhea/Phoebe ODE initialization sequence. - Force patching of software reset to system reset when Rhea/Phoebe is specified as optical disc type. (This is currently the only way for Pseudo Saturn Kai to get ODE's `reset_goto' feature to work) - Prevent from modifying some fields when some conditions are met : - optical disc : fixed to a given value in ROM-less mode. - software reset : fixed to a given value in when using Rhea/Phoebe ODEs. 2019/01/16 (Pseudo Saturn Kai, V6.279) : - Changed JHL loader to use CD-ROM load functions provided by BIOS when Rhea or Phoebe is specified as optical drive. 2019/01/16 (Pseudo Saturn Kai, V6.278) : - Fixed JHL loader support for RmenuKai. - Disable soft reset patch when using RmenuKai. - Improved RmenuKai/Pseudo Saturn Kai detection. (so far it was incorrectly enabling Pseudo Saturn Kai when an old version of the firmware was installed on cartridge) - In software reset patch, added CD Block reset (via SMPC) during software reset patch. (untested) 2019/01/11 (Pseudo Saturn Kai, V6.277) : - RmenuKai initial version. - In flasher utility, added version number display for latest lite and full Pseudo Saturn firmwares. - In Save Data Manager, fixed application title display after exiting from flasher menu. - Fixed CD Block initialization sequence for Rhea/Phoebe to show error message when SD card is not inserted into ODE. 2018/12/28 (Pseudo Saturn Kai, V6.274) : - Directly show DZ2SGM on startup when loaded from CD-ROM. - In DZ2SGM, added shortcut to credits page with L/R shoulder buttons from entries selection menu. 2018/12/27 (Pseudo Saturn Kai, V6.274) : - Removed cartridge expansion RAM initialization and testing. 2018/12/23 (Pseudo Saturn Kai, V6.272) : - Finished credits page for Pseudo Saturn Kai, Save Data Manager and DZ2SGM. - Added simple support for 3D pad analog arrow : so far 3D pad was supported, but only status of digital arrow was considered. Note : debug menus directly embedded in ROM for Virtual Memory Cartridge and cheat codes (example : BSOD screen, etc) are kept as-is so only digital arrow is supported there. Same limitation applies to standalone firmware flasher too. - Added retry access to CD-ROM (up to 5 times) when current access failed. 2018/12/06 (Pseudo Saturn Kai, V6.262) : - In ODE settings menu, fixed update condition regarding settings not requiring to reload disc image list. - In Save Data Manager, added the ability to return to main menu from flasher. - In flasher utilities, added warning message when trying to flash firmware other than Pseudo Saturn Kai full version on SST39SF040 chips used on USB dev cart or Gamer's Cartridge. 2018/12/03 (Pseudo Saturn Kai, V6.261) : - Fixed Japanese character display in menus. This was a regression from V6.257, caused by addition of font cache in menu. - Fixed display of strings larger than display area during "condensed" menu. 2018/11/28 (Pseudo Saturn Kai, V6.260) : - In ODE image selection menu, added images list ascending/descending settings. - In ODE image selection menu, added text justify (left or center) settings. - In ODE image selection menu, added setting for changing color theme. - In ODE settings menu, added option to enable compatibility reporter. 2018/11/26 (Pseudo Saturn Kai, V6.257) : - Added cache support for font used in menu items. Tested on real HW, and it seems to improve a little display performances when "condensed" menu is used. - In Dezaemon 2 SGM3, changed entry selection menu to "condensed" type. - In Dezaemon 2 SGM3, changed initial zoom factor in screenshots gallery from "all" to "1:1". 2018/10/02 (Pseudo Saturn Kai, V6.252) : - Added "condensed" (no border, and using proportional font) menu type. It is currently used in ODE image selection menu as well as in game and cheat code selection menus. - In ODE image settings menu, added a setting to toggle between "monospace" and "proportional" image selection menu type. - In ODE image selection menu, fixed sorting of multi-CD (with same release date) when sorting by release date or folder ID. - In ODE image selection menu, added update of setting to internal backup memory when toggling sort settings with Y button. 2018/08/04 (Pseudo Saturn Kai, V6.247) : - Cosmetic (minor) improvement in in Save Data Manager. - When using compatibility report, don't show cheat codes enable/disable menu when JHL loader (not compatible with vmem and cheat codes) is used. - Improved keys assignment in Pseudo Saturn Kai settings menu. 2018/07/27 (Pseudo Saturn Kai, V6.246) : - Experimental change regarding SD card access. 2018/07/24 (Pseudo Saturn Kai, V6.245) : - Added "autoboot" setting, allowing to enable or disable timeout in loader selection menu. - Cosmetic improvements in settings menu : show settings contents directly into menu, and don't clear display while updating settings, etc. - Rhea/Phoebe related : prevent from loading list after selecting an image. Before fix, this was freezing or crashing Pseudo Saturn Kai because of trying to read a file no longer available. - Rhea/Phoebe related : fixed saving of selected image. So far it was done only when using Virtual Memory Cartridge or compatibility reporter. It is now updated each time image selection menu is exited - In ODE image selection menu, fixed incorrect timing of keypress callback : so far it was called before updating selection, which caused incorrect (not up to date) cheat codes informations display. This was a regression from 20180629, caused by the fix related to intial key holding, and was concerning cheat codes selection menu too. - In ODE image selection menu, finished boot timeout feature : so far, remaining seconds until timeout and image information were mixed up at the bottom of the screen. - Improved SD card compatibility. 2018/07/12 (Pseudo Saturn Kai, V6.239) : - Fixed background image incorrect fading. It was sometimes happening when entering settings or credits from main menu. - Added background image fade transition between several menus. - Fixed incorrect text scroll in menus. This was happening credits or ODE image selection menus, when item length was equal to display width. - Added shortcut (Z button) for manual loader selection from ODE image selection menu. - Moved Rmenu entry from image selection menu to settings menu. It can be reached with L/R shoulder buttons from image selection menu. - Changed loader selection menu from "automatic only" to "CWX/auto/JHL" even when Saturn is indicated as modded in Pseudo Saturn Kai settings. - Added ODE menu configuration page, available with L/R shoulder buttons from image selection menu. - In ODE image selection menu, added several disc image sort types : alphabetical, by release date, by folder ID. - In ODE image selection menu, added name prettify enable/disable setting. - Slight speed improvement when alphabetically sorting ODE disc images. - Append disc image extra information (CD-ROM ID, region, date, version) to title when necessary. This is appended when two images got same title. - In ODE image selection menu, automatically select previously loaded image. It keeps the same image after changing image sort settings, or rmenu iso rebuild, but is reset when title is changed in LIST.INI, or when image with same title is added. - Removed Pseudo Saturn Kai demo. (is there still somebody using it ?) - Updated auto settings list. 2018/07/04 (Pseudo Saturn Kai, V6.231) : - Reworked credits display in Save Data Manager, as recently done in V6.224. - In ODE image selection menu, added status display when loading images list and when selecting an image. - Hide starfield display when it can't be animated. Concerns the following features : self test, CD-ROM loading, ODE initialization and configuration. - Added back "The Blinking Screen" ROM code for USB dev cart. It can be loaded with Z key on startup (won't do anything if USB port is not detected), or with "USB DMA Transfer" item from main menu. - Changed A+B+C+Start key shortcut from "exit to multiplayer" to "system reset" when CD lid is open during CD-ROM boot sequence. Reason : BIOS shows a black screen until lid is closed on my Japanese Grey Saturn when returning to multiplayer screen at that time. - In ODE image selection menu, changed sorting order in image selection menu. Before : ASCII order. Now : numbers, then letters, then special characters. - In ODE image selection menu, changed text justify from center to left in image selection menu. Also, temporarily disabled text prettify too. - Added settings save on Saturn internal backup memory. It currently saves optical disk type and link settings. - Added access to settings screen in lite version of the firmware. Purpose : allow Action Replay cartridge users to setup optical disc type. - Fixed RomFs consideration in Self Test feature : so far it was skipping it when RomFs was initially not correctlty detected. Now, it always tests when ROM is marked as containing Pseudo Saturn Kai full version. 2018/06/30 (Pseudo Saturn Kai, V6.227) : - Added alphabetical sorting support in ODE image selection menu. - Added automatic lowercase conversion in ODE images list. (It's a bit experimental for short words, and abbreviations, etc) - Source code cleanup regarding Indirect Dump feature. - Fixed incorrect display when initially holding key press in list-based menus. (This fix concerns all menus in Pseudo Saturn Kai and Save Data Manager) 2018/06/24 (Pseudo Saturn Kai, V6.224) : - Additional fixes regarding return to multiplayer when loading Save Data Manager. It wasn't correctly working in v6.213 ... - In order to reduce ROM usage, - Moved USB standalone firmware ("The Blinking Screen") to RomFs. This saved around 1KB of ROM for lite firmware. - Moved self test executable (flatcube by Mic) to RomFs. This saved around 5KB of ROM for lite firmware. When self test can't be read from RomFs, dummy test pattern is used and ability to execute self test program is disabled in that case. This happens when incorrectly selecting lite firmware when flashing cartridge, or when main executable could be decompressed, but RomFs CRC test failed. - Removed HexEdit feature, which saved around 3.7KB on ROM side. - In SD card self test feature, added CRC verification of data read back from SD card. So far, only size of data read back from SD card was checked. - Removed normal/fast boot setting. Instead, put fast boot enabled by default except when USB dev cart is connected to PC and ODE menu is not displayed. - Added Rhea/Phoebe ODE image selection support. This is a preliminary version that needs a lot of fixes and improvements. - In cheat codes BSOD screen, changed key processing in order to do system reset when "A+B+C+Start" key combo is pressed. (It was initially set to "Start" button only). Also, fixed few details regarding key processing. - Reworked credits display. Still need to do the same with Save Data Manager. - Added Rmenu log display to screen when Z button is pressed on firmware startup, instead of USB standalone firmware shortcut key. - Always show system status (which kind of cartridge used, etc) at the bottom of the screen : so far, it was displayed on first show of main menu only. It is however still cleared when user pushes a button during main menu. - In Save Data Manager, added debug menu regarding copy settings during cartridge ROM dump. This is for extra testing purpose only. - In Save Data Manager, added extra log output to SD card during indirect dump. Also, log whole internal backup RAM as well as dump header to SD card on every indirect dump pass. - Fixed stupid bug ignoring save data files with wrong case in vmem module. This caused problem when rebuiding saves list, or after manual copy of save files on PC, etc. - Fixed 3D pad support. So far it was causing exit to multiplayer when analog button or pad was moved. - In menu module, added X+Y+Z+Start key shortcut to system reset. - Fixed autodump disable setting. So far it was autodumping even if disabled. - Fixed custom logo (background image) import. So far, it was incorrectly cropping images not at 320x224 dimensions. (Special thanks to privateye for reminding me about theses two last ones : it was done a couple of weeks ago, and I already forgot about them :D) 2018/03/23 (Pseudo Saturn Kai, V6.213) : - Fixed emergency exits to multiplayer that were making a system reset. It is now possible to select between exit to multiplayer or reset the Saturn. Examples : "waiting for CD-ROM" screen, iapetus related error screens, etc. - In firmware flasher utilities, added flash ROM single page write test before actually overwriting whole ROM. - Removed rmenu related items in settings page. 2018/02/18 (Pseudo Saturn Kai, V6.209) : - Fixed incorrect decision between in-RAM and ROM-based cheat codes handlers. (ROM-based was always selected in previous beta) - Fixed cheat codes and cheat codes settings output to compatibility report. This was already implemented, but done after saving compatibility report file to SD card. Catched the occasion to add some minor changes and/or fixes. - Automatically disable cheats that would overlap. Example : "force vitality to 100%" + "force vitality to 75%". - Fixed a couple of goofy bugs happening when selecting a menu item while it was scrolling. (display of all items suddenly turned left justified, etc) 2018/02/09 (Pseudo Saturn Kai, V6.204) : - Added "USB only" cheat codes handler running in RAM. Partially assembly optimized. - Added "link diagnostic" feature in Pseudo Saturn Kai. Supports USB dev cart and legacy "comms" link. - Added Pseudo Saturn Kai logo in both firmware and Save Data Manager. - Allow transparent color (#FF00FF = pink) usage on BMP file when importing background image. Note : when transparent color is used, starfield is not drawn on image. - Added Virtual Memory Cartridge support via USB dev cart to file on PC. For debug purpose only. Requires SatLink running on PC side. - Minor cosmetic fixes on flasher. Both standalone flasher and the one integrated in Save Data Manager were affected. - Fixed save list browse menu emergency exit when showing contents of empty save device in Save Data Manager. Now automatically skip display of empty devices, instead of exiting to parent menu when listing empty backup device. - Added debug feature to read indirect dump data from PC link instead of backup memory or FDD. - Added a couple of legacy firmwares to flasher. Also added missing screenshots for (nearly) all firmwares in flasher menu. - Added save/restore of custom cheat codes from/to PC link. (for debug purpose only, not available when USB dev cart is not detected) - Added Virtual Memory Cart / FDD selection menu when automatically or manually loading Save Data Manager. Games using FDD don't prompt for FDD and directly use Virtual Memory Cart even when FDD is connected. Use manual loader in the case it is needed to use saves from FDD. 2017/12/18 (Pseudo Saturn Kai, V6.184) : - Added autoset feature, untested when JHL loader is required. (CWX loader should work as on previous versions) - Added cheat codes support in compatibility report feature. - CRC[E34703CC]CRC[D253387D] : fixed master code location, and tested on real hardware Unusual location is used, hence may cause troubles in unusual stages such as boss, extra menus, etc. - CRC[264990EF] : fixed "play level xyz" cheats, and tested on real HW. Each cheats now use one code, instead of two before fix, but level number is no longer incremented. 2017/11/13 (Pseudo Saturn Kai, V6.175) : - Added 2KB reserved to cheat codes in vmem workram structure definition. - Added few test cheat codes for use with Save Data Manager. - Added redirection to BSOD from soft reset (A+B+C+Start key combo). Optional debug feature : it usually redirects to system reset. - Major fixes and screen layout improvements in BSOD screen. - Major changes in cheat codes interrupt handler. - Major speed improvement in in-RAM cheat codes handler. Now fits into 34 SH-2 instructions ! - Added "0xA5 fill/detect feature" in order to look for cheat codes handler location (`B' code). - Added custom cheat codes input screen. (Debug purpose only) - Added compatibility reporter support for cheat codes features. Works with Gamer's Cartridge only. - Removed unused UBC and bioshack init modes from vmem. 2017/10/15 (Pseudo Saturn Kai, V6.147) : - Menu items multiple selection fix, regression from version 6.142. - Allow scrolling in menus when text is larger than display width. -> Cheat and game selection menus now scroll large text, but it is currently limited to maximum 44 characters in order to reduce cheat codes memory usage. - More IP header CRCs in cheat codes list. 2017/10/05 (Pseudo Saturn Kai, V6.142) : - In menus allowing multiple selection, select current item with A/C/Start button only when no other item is selected. - IP header CRC related fix in cheat codes list. 2017/09/28 (Pseudo Saturn Kai, V6.141) : - Allow to specify more than one IP header CRC per game in cheat codes list - Added IP header CRCs for around 75% of all the games in list. - Improved cheat codes generation report : report CRC collision, games without CRC, full list of cheat codes list, etc. - Added the ability to specify disabled item (for sub-menu purpose) and item enabled by default in cheat codes list.

If CRC not found, default select game with title nearest to title of game about to load in cheat codes games selection menu. - Added cartridge ROM-less cheat codes handler. Purpose : slight speed-up of cheat codes interrupt. Demerit : small limit of codes useable simultaneously, USB connectivity not available. - Moved master code information (patch address/code and work RAM location) from codes list (ROM) to games list (RAM, compressed with main executable). This saved around 3KB of ROM usage. - Added two steps cheat codes initialization sequence, in order to keep Sega logo clean when booting a game ... currently not working hence disabled. - In cheat codes options menu, allow to fill unused HRAM with non-zero value (0xA5).
