As indicated in the title, I tried a new PCB color ! This time, this is yellow
Rare picture where all PCB colors I tried so far are gathered
The manufacturing of theses yellow PCBs took a bit longer than usual : maybe was it because this color is not ordered frequently ? Or just a bad luck with timings ? I don't know, but anyway I'm definitely more at ease with good old green color
Blue PCB in the picture above also needs some attention because it's quite a long time I didn't soldered PCBs with such color. In fact, it was probably the first time for this Gamer's Cartridge PCB revision
So, what's the reason why this article is posted so early ? I mean, pictures of theses PCBs were taken around one month ago, while preparation for one article here is usually in the half a year range, with majority of articles are canceled in the midway of their preparation Well, the reason comes from accidentally watching TV recently, and realizing that colors match a given pattern !
Gamer's Cartridge, Olympic Games Edition
That would had be the the occasion to do some fancy "Gamer's Cartridge Olympic Games (C) (R) TM Edition" advertisements on all major social networks, modifying prices during this period, make sponsorship with some whatever sportswear brands, but I don't like such kind of show business, and ... the fact PCB colors match those on the Olympic flag is a coincidence
So, I'm glad to introduce you Gamer's Cartridge at the Olympic Games colors ! There's no sponsorship, no changes in the prices, no super event (except this poor blog article), but Saturn projects are still my favorite hobby, which is the most important
PS : I unfortunately no longer have all PCB colors gathered in first picture of this article, so
it's not possible the re-take a picture in same layout as Olympic flag.
PPS : there wasn't snowball fight Olympic discipline this time too Let's hope next edition will finally feature competition of a sport which I understand the rules
According to wikipedia, it seems that Japanese version of Panzer Dragoon Saga turned 20 years old this week, so,
Happy Birthday
Panzer Dragoon Saga !
Hrm, I feel old to hear over and over that games I played in my childhood are becoming vintage ... time flies
So well, I don't want to write an article for the anniversary of each Saturn game That's too depressing, and I prefer to use this time for other things The reason for this article is to help people wanting to play Panzer Dragoon Saga, but not from level 1, and failing to find appropriate save states for use on their Saturn.
There aren't many saves for Panzer Dragoon save files available for importing from Save Data Manager, but good quality saves can be found on Panzer Dragoon Legacy homepage :
The reason why theses saves aren't added to Pseudo Saturn Kai Save
Data Manager CDROM is because the readme included with theses saves states that saves can't be hosted elsewhere than on Panzer Dragoon Legacy. I personally think this is a pity, because theses saves are really
good. (2018/02/12 : it seems OK regarding copyright See the bottom of this article for details)
Panzer Dragoon Saga is one of the few games not allowing in-game
usage of Gamer's Cartridge. A workaround to that is to use
Saturn's internal backup memory.
So, it is possible to import theses saves to Saturn's internal
backup memory by using Gamer's Cartridge and Save Data Import
feature :
1. Copy all save data folders from archive to SD card → SAVES
folder
2. Insert Gamer's Cartridge into Saturn, power on Saturn
3. From main menu, select "Save Data Manager"
4. Select "Save Data Import"
5. Browse for save data file where to import from
Example : SAVES folder → saga_01 → BKRAM1.BIN
6. Select all saves with Y button and confirm import to internal
memory device with A button
Then, it is possible to use theses saves from the game. Unfortunately, Panzer Dragoon Saga is one of the few games not supporting in-game memory cartridge support with Gamer's Cartridge, so the only workaround is to use Saturn internal backup memory. 2018/02/12 : the steps above are still valid, but work on Gamer's Cartridge only. Next release of Pseudo Saturn Kai will feature theses saves directly from Save Data Manager, so that theses will be available for Action Replay cartridges users too (See the bottom of this article for details)
I hope I will be able to make this game compatible with Gamer's Cartridge in the future ! I recently tried to find what's causing this game not working ... and realized it would be harder to fix (I thought game was re-authenticating CD-ROM just before starting to play, but I didn't found any code doing that) I'm not a genius programmer, but on the other hand, I don't give up on the first failure I meet, so hope next attempt to fix support for this game will be the good one
Update 2018/02/12 : I just received the agreement to add theses saves to Save Data Manager More details can be found on Panzer Dragoon Legacy forums, and screen copy of related posts are available here for the records. Special thanks to Solo_Wing, who solved this problem in a couple of messages ! Please keep the good work
Synthesis ... this is the kind of blog article posted at the end of December in normal blogs, but since this is not a normal blog, and that I can't respect any schedule for it, let's prepare this article at the beginning of January
Last year started well with an order of Gamer's Cartridge from IGK, who is administrator of Dezaemon DB homepage. More than administrating Dezaemon DB, he is also a dezaemoner who (among other titles) developed Biometal Nemesis, which deserves its youtube link in this blog :)
Biometal Nemesis - Click above if you like shmups
I really like the style of this Dezaemon game ! Thank you very much IGK for creating such gem
Thanks to IGK, it was possible to finish support of Saturn Floppy Disk Drive on Save Data Manager : initialization of this device is slightly different than with internal backup memory and backup memory cartridge, and consequently was causing troubles on various configurations such as no backup memory cartridge inserted, but floppy disk connected, etc. Fixing all possible patterns wouldn't had been possible without kind help and beta testing from IGK. Thank you
Save Data Manager (version around 2017/01/30)
Configuration when this screen was taken was no "backup memory cartridge inserted, and floppy disk connected", which was causing troubles because among other things, unavailable device in the middle of devices table wasn't supported.
Additionally, this was the occasion to add virtual floppy disk support on Gamer's Cartridge, making Saturn considering a floppy disk drive is available, even if not physically connected. Main purpose of this feature is to add 5 more save and load slots in Dezaemon 2, which, in addition of the 5 slots on backup memory cartridge, makes possible to manage up to 10 saves into a Dezaemon 2 session directly from a single SD card I don't remember exactly what was the trigger which started the addition of this feature, but I think that a suggestion from IGK like "it would be cool if floppy disk would be supported by Gamer's Cartridge too" and me "Ah yeah, that's a nice idea ... how many save slots do you want ?"
After that, IGK continued to surprise me by asking his friend beebaraka to draw a Dezaemon 2 themed label for Gamer's Cartridge ... As a result, I received images for two labels, which I personally consider as the masterpieces among Gamer's Cartridge label collection My preference goes to the white-themed label, but I suppose it's just a matter of personal taste.
Dezaemon 2 themed Gamer's Cartridges
Like shooting games ? Like DIY ? Theses cartridges are designed for you
In parallel of theses Dezaemon 2 adventures, generous contributors helped in dumping firmware of some exotic Saturn cartridges, and were successfully added to Pseudo Saturn Kai Save Data Manager. Most relevant dumps were for X-Terminator cartridge, and Urawaza Dataro cartridge : first one is a cartridge with extended support for cheat codes, especially with extra controller allowing in-game search of cheat codes. Later one provides special save data for several (around 34 IIRC) Japanese games. Special thanks to Madrom for providing dump of this cartridge !
All the points below contributed to prepare the "20170423" release of Pseudo Saturn Kai. Warm thanks to all contributors who could make it possible !
Second half of the year mostly concerned cheat codes addition to Pseudo Saturn Kai. It started in June (or May ... I don't remember correctly) from a Gamer's Cartridge user asking when cheat codes will be available in Pseudo Saturn Kai ... this reminded me I still had to finish that until next release
First working version of cheat codes
hander, with USB transfer support
It's not visible on this picture, but many polygons weren't
drawn because of performance issues.
Unlimited time cheat code working : it took me around
one month to fix missing polygons, because of unoptimized
implementation of cheat codes handler), but I did it
Cheat codes kept me busy for six solid months, basically in understanding to manage cheat codes in a similar way as is it done on Action Replay firmware, optimizing critical code, importing codes list, finishing cheat codes related interface, testing several games, etc. That's honestly a hard work, but this was also an occasion to add in-game USB transfer via USB dev cart. Thanks to this, the basis in order to fix or improve cheat codes is ready Proper PC software for cheat codes detection is still missing, but hopefully this will be done someday.

This game was a nasty one regarding cheat code support, with very
tight CPU and RAM left for cheat codes handler. This was an occasion
to develop many cheat codes debug features
Summer was also the occasion for me to officially end manufacturing and support of USB dev cart : after 5 years involved in this adventure, I considered it was enough, because : 1. USB dev cart interests basically nobody 2. In the rare cases USB dev cart interests somebody, it is usually used for closed-source projects (But there are notable exceptions where USB dev cart contributed to Saturn open source projects. Big thanks to theses concerned peoples for making Saturn homebrew scene brighter )
I'm hesitating about the timing for next Pseudo Saturn Kai release : should I take some extra months in order to get proper cheat codes support for most popular games ? Or should I release it under few weeks with minimal cheat codes support (around an handful of games are currently tested and working), and hope to receive some feedback from users, so that I will eventually know which games need their cheat codes to be fixed ?
That's a very difficult choice : cheat codes is a niche feature (as everything else regarding Saturn !), so I shouldn't hope a lot of feedback. On the other hand, adding a cheat codes edition screen, and allowing cheat codes input on user side is (IMHO) a mistake too : maybe a motivated user would fix and/or add codes for some games, but rarely theses codes will be publicly available for everybody else, and in the other cases, user will simply consider Pseudo Saturn Kai cheat codes as a broken feature. Let's see ... I honestly don't have any precise idea when next release should be done. Any suggestion regarding this is welcome in the comments
Generally speaking, I'm tired about Pseudo Saturn Kai maintenance : I started it around two years ago (yes, largely over than nine thousands hours !!!), edit: that was around three years ago (I though we were at the beginning of year 2017 ), am finally seeing the end of my TODO list to realize that ... majority of users shifted to hardware ODE, or simply left the scene without any last final word ...
Well, whatever it may be, I continue development of Pseudo Saturn Kai because I went too far to stop so near of the end (that's quite a pragmatic argument, sorry), but also (and that's the most important), because that's a nice hobby, which is important in order to keep a balance between private and work
Also, my first steps in Pseudo Saturn Kai maintenance were made during my hospitalization for cancer, and keeping such hobby during theses hard times was worth gold. I don't know (and don't want to know) how things would had turned without my Saturn hobbies.
BTW, things concerning my health are getting well : I'm still undergoing periodical screening, which all were OK last year Last year was the celebration of 3 years all right after surgery, which is not bad for a cancer with 50-60% 5 years survival rate
Pokemon Go still not allowed in hospital. Fortunately, usage Saturn dev laptop isn't forbidden
To finish this article on a rant note (sorry if you went here for some final positive note ), I would like to say "thank you for nothing" to Rhea/Phoebe development team rmenu author. (← updated on 2018/06/20)
Why ? Reason is that I would like to add a rmenu equivalent to Pseudo Saturn Kai, but don't have any technical information to implement it, and it's not like I didn't asked about theses informations, but simply didn't received any relevant reply from concerned developer(s).
For a semi-commercial product, I can understand to keep schematics, source codes and other development resources private. But I don't request disclosure of theses resources, and just want some minimal information for interoperability, which isn't publicly available, and that's a pity.
Why is that a pity ? Because some cheat codes will certainly not work by having rmenu running between Pseudo Saturn Kai and Saturn game. I know there's the solution to use rmenu's full boot, which does a system reset of nearly everything (except Rhea/Phoebe, obviously) after selecting a game, so that cheat codes can be enabled after that ... but I really don't know anybody motivated to do this messy setup : everybody is using the rmenu's quick boot solution, right ?
Pseudo Saturn Kai's rmenu, dated 20151214. Latest version have some major improvements, such as scrolling title of select game, etc Because of lack of Rhea/Phoebe API, this feature is disabled.
I'm personally (and honestly) not concerned about this problem : my modded Saturn + USB dev cart are enough for my development needs, and I don't want to pay for a device costing an arm and a leg (plus a kidney when buying from ebay ...) and then having to do the reverse-engineering job for it after that ! So unless I got external help, clean support for Rhea/Phoebe will be done ... without me
From what I could found from static analysis of rmenu itself, version is checked by seeking to the last available data sector of the CD track, and game is selected by seeking to sectors just before that last available one.
After that's it's difficult to guess what data should be expected from Rhea/Phoebe without testing on real hardware. And reverse-engineering is usually a sluggish and hard work (I estimate the remaining as around a two weeks course ... and hope this to be a pessimistic estimation), and really would like to spend this time to other projects funnier.
2018/06/20 update : there will be proper support of Rhea/Phoebe image selection in Pseudo Saturn Kai, and consequently an user-friendly way of enabling cheat codes when using theses ODE
Very big thanks to Deunan Knute for the great job, providing the technical informations and everything else
And also I would like to thank privateye for contacting Deunan, his patience and great help in beta testing
So I'm currently preparing next batch of Gamer's Cartridge, and am glad to introduce new PCB color
Gamer's Cartridge PCBs in various colors
I unfortunately didn't had blue Rev 3.3 (b) PCB when taking the picture above ... in fact, it's a long time I didn't soldered blue PCBs
The main interest in soldering PCBs with different colors is to make soldering activity funny, which is important for me since cartridges are assembled by hand : if making cartridges would become boring, I would prefer to stop everything rather than automatize assembly process !
My impressions after soldering a black PCB are ... a bit mixed : yeah, the PCB looks cool, but there's no contrast between tracks and isolated areas, so I definitely wouldn't use this color for new projects One example of this lack of contrast can be found in cow logo, whose rendering is terrible in black color :
Cow logo on black PCB ... playing hide and seek
Among PCB colors I tried so far, I personally prefer ... standard green color, and then maybe red color. Also, I still didn't tested yellow color, so let's try it on next batch I fear that contrast won't be better than on green PCB however
Among the boring tasks remaining in Pseudo Saturn Kai development, there was "IP header CRCs merge to cheat codes list" task remaining ... ... There was, because I finally finished to merge the CRCs I could gather here ! Well, I think there are still 20-30% of the games in cheat codes list still not associated with any CRC, but anyway that's a fair amount of work done so far
Last CRC merged, at the end of cheat codes list Left text file : list of IP headers and their CRCs for each games I have here Right text file : Pseudo Saturn Kai cheat codes list
What is that CRC thing ? That's a value I use in order to identify each Saturn games. Thanks to such CRC value, it's possible to easily associate each cheat codes to a given game, and consequently automatically select game in cheat codes list according to CD-ROM inserted in Saturn CD lid. You don't like to manually select a game from cheat codes "select game" menu ? Me too So that I added this "automagically select game" thing in Pseudo Saturn Kai cheat code feature
By the way, it's probably a bit late for a surprise effect, but I'm glad to to announce that cheat codes feature will be available in Pseudo Saturn Kai next release
Basically, cheat codes handler now works ... for a majority of games tested so far. And user interface regarding cheat codes stuff is more or less okay ... but still needs to be perfected here and there.
So as you guessed, there are still details to complete until considering Pseudo Saturn Kai cheat codes feature ready for public release, and unfortunately polishing details usually (always) require time in software development, so let's hope next release will be available in a near future, which is "this year" in my own time scale regarding Saturn projects
Nights into dream cheat codes working ! That's the first game I used in order to test assembly version
of cheat codes handler

In-game memory contents are mine ! Ph34r my l33t h4Cklng sKI1lZ
So, the next development jobs are to support multiple CRCs per game : cheat codes list have several CRCs defined for some games (this is typically used for games using several CD-ROMs), but Pseudo Saturn Kai currently supports one CRC per game. Modifying the cheats list → data conversion utility in order to support multiple CRCs will be also an occasion to add some extra verification stuff regarding CRC, such as verifying that two different games don't collide on the same CRC, which is something like around 2500 different CDs versus 4 billions possible CRCs ... hence should be OK, but who know what may happen when developing software
After that, it will be probably be the time to do some testing on as many games as possible, in order to verify that cheat code and game are correctly associated, and to verify that cheat codes are correctly working, etc. Such task will require a significant manpower, hence to find a lot of beta testers. So if you're ready to give a hand, please stay tuned
