As usual I'm not very on time for sending my best wishes but I hope that everyone spent a nice Christmas and are appreciating winter vacations To add even more fun to theses vacations, I'm happy to announce that latest flavor of Pseudo Saturn Kai is -finally- publicly available !
To be frank, there are no new major feature for Pseudo Saturn Kai in this release : the most important news is not hidden in Pseudo Saturn Kai itself, but in Save Data Manager, with a new edition of Dezaemon 2 Save Game Manager, featuring 11 new opus !
Regarding this new edition of Dezaemon 2 Save Game Manager, I really want to thank each respective contributor for their passionate work in shmup creation : - mk2, designer of DAIOH Huricane Special - WANG, designer of Houkou Tiger
Also featuring screenshots gallery of DAIOH Hurricane
I also would like to give a special thanks to Dezaemon DB (wiki) for all his support around floppy disk emulation in Gamer's Cartridge and motivating me in developing a new blend of Save Game Manager for Dezaemon 2, which then turned into Save Game Manager 3 (released on last Winter) and Save Game Manager 4, freshly releasing right now. Unfortunately I didn't received any news from Dezaemon DB for more than two years, but I continue to believe he will be back in action in Dezaemon community someday.
Regarding Pseudo Saturn Kai itself, majority of changes in this release concern fixes in automatic game loader and cheat codes list. So if previous version of Pseudo Saturn Kai installed on your cartridge are working fine with your favorite games library, then ... theses games will continue to play fine with latest version.
All theses improvements were directed by privateye, who really deserve warm thanks for this huge work !!
It's a big task to get a project working more or less correctly as it was in previous releases of Pseudo Saturn Kai. But it's an even bigger task when trying to fix all the little details around that project Without privateye, Pseudo Saturn Kai certainly wouldn't had its edges polished so well
And, Gamer's Cartridge users may appreciate that a problem sometimes happening when retrieving Saturn date and time has been fixed in this release.
This bug was introduced in previous (6.314) version because I didn't checked enough side effects of modification done at that time to add support for wireless pads.
Concretely speaking, this fixes the file time stamp of save data files as well as folder naming (which is based on Saturn date) when dumping save(s) to SD card.
Except that, Gamer's Cartridge support is equivalent to previous version, so if you don't want to brick your Gamer's Cartridge (risk is super low, but I can't assert it to be zero), then continuing using previous version may be a wise choice. After all, rather than upgrading to latest firmware, the most important is to play your favorite games
TL;DR : Gamer's Cartridge are no longer available. It's not an end of the project but if back for sale, it will likely to be in limited quantity.
This is to announce that Gamer's Cartridge are out of stock for an undefined period of time. That may look sudden, but I was scheduling this transition for around one year ... and kept it confidential until now to avoid an eventual rush of orders, or people purchasing my cartridges just for stocking "in case of" or for speculation without actually playing with their Saturn.
The reason(s) why
Why are Gamer's Cartridge out of stock ? First, this is for the simple reason that I don't have any Action Replay shell for assembling new carts : my friend who supplied shells stopped provisioning from wholesale supplier around one year ago.
So I bought all the remaining stock from that friend, and that stock kept me busy this year in manufacturing and selling last batches Gamer's Cartridge.
Now that my Action shells storage facility (which is maybe a bit pedantic term to speak about a couple of shoes box ) is empty and that I found the time and motivation to write this article, it's time to officially put Gamer's Cartridge project on pause.
That pause may be temporary or the last one ... I honestly don't know how the project will evolve, but what's sure is that it won't be available back in short term and in the case it shall become available back, this will be in limited quantities.
Another reason for Gamer's Cartridge being out of stock is the decline of public interest toward it : back on initial release in 2016, Gamer's Cartridge was relatively popular because its unique "virtual" memory cartridge feature. At that time, Action Replay flashed with Pseudo Saturn Kai was a standard to play Saturn games but unfortunately this solution didn't featured cartridge backup memory, so that Gamer's Cartridge was here to fill this gap.
But I clearly felt the recent rise of "all-in-one" red cartridges because time until each Gamer's Cartridge batch is sold became longer by longer from the beginning of this year, from "few hours" in 2016, it became "several days" recently
As of Gamer's Cartridge main developer and manufacturer my opinion is a bit biased, but I consider Gamer's Cartridge a better solution than the red cart because backup memory capacity is larger, access to Saturn floppy disk device is emulated, and also because save data contents can be easily backed up to modern media. But on the other hand, as expansion 1MB/4MB RAM isn't available and that Gamer's Cartridge are hand made by one dude during its free time, maybe customers were more in confidence in the red cart because it mass produced, or a bit cheaper, or more convenient because it's "all-in-one". Who knows.
Also, the approaching public release of Satisfier project will certainly make possible the backup of cartridge memory contents to SD card, also provide the ability to dump Saturn BIOS there too. This overlaps few of the few remaining "Gamer's Cartridge exclusive" features.
Last remaining "sales point" of Gamer's Cartridge is to offer a *reliable* in-game save data support : all the other backup memory cartridges (including Sega official ones !) are prone to corrupt save data when not correctly inserted.
This was improved with Gamer's Cartridge, which shows an error message on startup (without botching any user data) if not correctly inserted. If Pseudo Saturn Kai boots then save data are saved in a reliable way
But as typical user don't care about data reliability, there soon will be no more room left for Gamer's Cartridge in the portfolio of retro gaming devices for Saturn.
Whatever it may be, it's stupid to continue Gamer's Cartridge manufacturing if I struggle to sell theses. Maybe aggressive marketing or promoting my projects here and there on social media would had made a difference, but that's clearly not the path I want for my projects : I don't do that for a living and don't want to influence potential customers just to increase my pocket momey. If it interests someone then that's cool, but on the other case I won't force anybody to buy my homemade stuff and rather shall temporarily close the store and go on other projects.

Life-prolonging treatments for Gamer's Cartridge ?
There are some solutions to continue Gamer's Cartridge manufacturing a bit, but as the "life-prolonging" title suggest, theses are flawed and/or limited and I will explain you why.
Supplying shells from another source ? That may be a viable solution, but honestly I didn't examined it in depth : that's a significant amount of time to ask several places about my project, my needs, etc etc ... without any guarantee to get something at the end. Well, I may think about this solution someday but right now I prefer to dedicate my free time to projects other than writing tons of emails
Supplying shells from wholesale manufacturer such as EMS ? Big manufacturer have the advantage to (usually) be stable on the long term and to offer broken prices ... but the advantages stop here. On the other side it requires a commitment on my side to buy in large quantities, hence to manufacture Gamer's Cartridge in large quantities, and finally to sell in large quantities.
This "large quantity" point is clearly not what I want for my project : for me, Saturn is just an hobby which I don't want to be a source of stress (what should I do with remaining stock of unsold carts, electronic parts and shells if by example Gamer's Cartridge would be "3rd party copied" and that all customers prefer to purchase that because it's $20 cheaper ?), and I consider this was a wise choice to do such kind "limited manufacturing" because at some point Gamer's Cartridge lost interest from public. To give an idea of magnitude between my projects and mass produced ones, unit used for mass-produced things is probably (I don't know in details) around "large cardboard", or "palette". On my side, the until is "shoes box"
Cartridges without shells ? That's a big no : if that's to then hear that the quality of my carts is shabby I prefer to leave here on a good impression. Additionally, if that's to also hear that because of the lack of shell my cartridges have to be put on discount that's another NO too. Prices of my carts are decided after a long work of research and introspection () so I don't want to hear any kind of price reduction after that. If you want a cheap cartridge, the red "all-in-one" cart is all for you.
Providing shell from customer' space Action Replay ? No thanks. I have better things to do than waiting for your spare Action Replay, to mount a Gamer's Cartride inside (which includes to drill and cut the shell etc) and then stick your favorite label on it As indicated above, ideal quantity for my cartridge projects is "shoes box" : I prepare a batch of cartridges from a shoes box of parts to another shoes box of "ready to sell" carts. Doing individual manufacturing for only one user just fulfills the personal interest of that user but except that it completely counter-productive ...
Open Source ? That's completely NO : open sourcing Gamer's Cartridge project would yield around $20 price cut on user side. On my side, it would yield to the disappearing of pocket money to challenge in more complex projects.
I don't have anything against open source, but I'm completely against the ones that beg open sourcing just for their personal own interest, i.e. saving more or less 20 bucks in the case of Gamer's Cartridge. Maybe that's quick money saved for them, but on the other hand that's also innovation in new Saturn projects being destroyed : I certainly wouldn't had pushed Pseudo Saturn Kai development so far (for example around cheat codes and Rhea/Phoebe disc image selection support) if in the meanwhile of the development 3rd party manufacturers would had made profits from my hardware projects.
DIY Kit ? That's more or less same as open source solution : it's just a simplistic solution to satisfy one's personal interest. Additionally, it's a source of troubles in the case that DIY Gamer's Cartridge doesn't works : is it caused by electronic parts (= my responsibility) or soldering and assembly (= user's responsibility) ? In the case of "one man show project" as I'm doing, everything is simpler because I'm responsible of everything when a problem happens
3D Printed Shells ? It's an interesting solution, but this requires to use a completely new manufacturing process for me, with all the related matters (verifying solidity, tweaking shape, selecting appropriate color and base materials etc) ... and all the unexpected problems too : from my own experience, there are high chances of being stuck into unexpected problems when challenging in something new
To give an idea of my apprehension regarding 3D printed shells, let's take a look on Pyra portable laptop development : project started several years ago and now electronic and firmware/OS side of the project seems stable. It's however not released yet because of ... unexpected problems regarding shell manufacturing.
That's not a critic about Pyra project (in fact, I'm following it with admiration), but just an example to detail how bad development can be delayed when you're trying new process or new project.
And for theses reasons above (of extra design, tweaks and risks) as well as in regard of the limited public interest into Gamer's Cartridge this is probably not a good way to do. This would however make sense on a new hardware project.
BTW, I do have some spare 3D shells, but at theses were a generous present to me from their creator theses are not for sale and consequently it's not worth asking if I could sell a Gamer's Cartridge with theses shells.
Official memory cartridge shells ?
Very first Gamer's Cartridge assembled back in 2016 were using shells from official memory cartridge, so this is a good "B-plan solution" to continue manufacturing of Gamer's Cartridge. And on the good side, gathering some used memory cartridges would be the occasion to dump and share the saves eventually left by previous users on theses cartridges
This however needs some tuning on PCB, because status LEDs of theses very first Gamer's Cartridges are currently positioned in the area reserved for cartridge label.
And unlike 3D printed shells, the solidity and other mechanic small details around those official memory cartridge shells should not be a problem, but overall state may be a bit questionable : upper half of the cartridge may be yellow, previous label may be a mess to remove etc. I personally don't care such kind of "retro Gamer's Cartridges" might look not "pristine as new", because as the project name suggests I want my cartridges to be used for playing rather than collecting, but I'm concerned if cartridges don't sell well ... let's wait and see if that's a reasonable solution or not.
Regrets about Gamer's Cartridge
This kind of farewell article traditionally features a "this point should had be done better etc", but I don't have any regrets around Gamer's Cartridge development !!! When releasing Gamer's Cartridge, I thought the project would last for half a year and then be cloned or overtaken by a more competitive (widely available/more features/cheaper : maximum two choices possible), but this project actually lasted for more than three years This was an occasion to meet many people who then became good friends (more details in the "Thanks" sections below) and/or gave extensive help around Pseudo Saturn Kai development. Without them, the limits Pseudo Saturn Kai wouldn't had been pushed that far
This wasn't an occasion for me to become rich, and this was as expected ! Making big cash from retro gaming project requires mass production, which I'm not interested in because for me, Gamer's Cartridge was just a toy and the activity to develop and manufacture theses was just an hobby.
I don't think it's good to go over that toy/hobby limit, because if an hobby becomes a business, it's no longer an hobby
This wasn't an occasion to become famous too : I wasn't approached by famous personalities from social networks about Gamer's Cartridge (nor about Pseudo Saturn Kai too), but everything is well like that as rather than hype I simply want to contribute to a better public interest on homebrew development and Saturn in general.
Testimonies
Many project proudly show feedback from their happy customers, and now it's time to announce stock and production shortage, I realize something similar wasn't available for Gamer's Cartridge !
"All-in-one" cartridge customer feedbacks
As listing feedback from hapy customers is too mainstrean, let's show feedback from users who didn't purchased Gamer's Cartridge
- - - - - - - - - - - - -
(After explaining over several emails that Gamer's Cartridge isn't an EverDrive and giving links to Saturn ODE project in the case this fits better potential customer's needs)
"Thanks for your time"
→ You're welcome, and thank you for teaching me this expression to decline something in a clever manner It will now take a place of choice in my library of useful English expressions.
- - - - - - - - - - - - -
(After detailing about Gamer's Cartridge features and disclaimer)
"I see. I bought an USB Data Link instead."
→ Well, that's better than not replying to my email after ordering a cartridge : at least I don't need to reserve this cartridge during several days for nothing
- - - - - - - - - - - - -
"Will you release DIY kits ?"
→ NO! PCBs are publicly available, and appropriate MAX3000A CPLD can be found on ebay so that you can assemble everything by yourself. CPLD firmware isn't available, but please have fun in re-implementing Gamer's Cartridge logic inside. I learned VHDL like that.
(Note : feedbacks displayed above are the result of several individual feedbacks mixed together, so that general trend about Gamer's Cartridge is discribed, and anonymity of their authors is preserved)
Thanks

The Future
I wish Saturn community a bright future with Satisfier and "all-in-one" red cartridges. The first project shall bring ability to export saves to SD card, also contribute to homebrew games development as also shall feature a nice disk image selection menu someday too. The second project shall bring a an affordable and convenient cartridge support for "all" Saturn games.
On my side, as I now have additional free time from the pause in Gamer's Cartridge manufacturing I would like to focus on the development of old frozen projects.
As usual, I won't communicate about any ETA, development cost nor even what it is about until things are working well enough : that will be less pressure on my side, and less frustration on your side
25
years ... that's a quarter of a century ! I feel old to realize that
but shall do my best to continue loving my Saturn for the next incoming
25 years
Webou (which host PPcenter) was kindly providing HTTPS for already a long while but my homemade CMS was messing up the display of my homepage : for obscure reason (I honestly don't remember why) it was trying to load the page's CSS from an absolute URL, including the "http", and as HTTPS doesn't really likes to load something from an unsecured location, the CSS was discarded so that the page display was ... minimalistic
Saturn cartridges page before fixing HTTPS support
This is now fixed, and additionally trying to use plain HTTP should also magically redirect to HTTPS.
That's quite helpful, because all the labels for Gamer's Cartridge are referring my homepage as "HTTP" (*) and I really didn't wanted to have to re-design theses labels
Just a small article to inform that NinPen Manmaru translation patch was updated recently : I was reported that the game freezes after beating the final boss and that this could be fixed by using original (Japanese) script file instead of the translated one during that moment.
So this update of the translation patch is just a lazy implementation of what's described above : before overwriting script files with translated ones, the file used after beating final boss is renamed so that Japanese one is kept
At some moment I wanted to do something better regarding this translation project, such as translating in-game images :
Me trying to convert images to
standard format : the cut scene
In-game image correctly converted on second try
But that concerns so few screens (typically, regarding memory cartridge setup) that the game is playable as-is.
And also, I'm not that motivated to do translation work to then see physical copies for sale on some kind of stores for retro-gaming; so far I did my best to make my projects available for a large majority of players (Pseudo Saturn Kai itself doesn't costs a dime and can be installed on cheap Action Replay-ish cartridges, there are no kind of advertisement nor crowdfunding requests on my homepage, etc), so on the other side it's quite frustrating to see other retro gaming teams making cash on other people's work ...
To end on a positive note, I would like to add from the fact it could be verified that -except the small problem above- the game could work fine until last boss, it's fairly sure that the two "NINMES.DA" and "NINOMAKE.DA" are not necessary to play the game.
Consequently the "Press Enter to continue patching at your own risks" message caused by theses two files can be safely ignored during the patching process
It took one eye blink from previous article to directly arrive on today, the last day of September ... time flies
And, in application of the contract between my Saturn projects and PPCenter, I have to write at least one blog article per month (*)
My remaining free time for this month is around 20 minutes, so I'm hurrying up to write an article
(*) PPCenter is the entity which manages the hobbies I do on my spare time. As a consequence, it also manages the revenues earned from my homebrew projects, which is why I should finish this damn article if I want to eat something else than cup noodles during next month
So I hope this Q&D article will please you, and in the meantime of this page being loaded, don't forget to send me a donation ! Every little bit helps and contribute to pay my the gasoline for my car as well as three meals per day
Custom Cartridge Shells
(as indicated in the title)
A while ago, I finally decided to put public the page about custom shells for my cartridges. Theses were designed, 3D-printed and offered by Zone66x : he is the only one to deserves the credits for this hard work
Main interest of theses custom shells is to have their shape carefully designed to hold SD card on the top of the cartridge : with regular shell made from Action Replay shells, the SD card sticks out by 2-3 mm, which was improved on custom shells with have enclosure to be at the same height of SD card's.
Another good point is that theses shells were prototyped in several shapes and colors ! I personally like transparent shells like this one
About the points that put the advantage on Action Replay shells is the solidity : Action Replay shells are way more stronger, but this was expected because theses are "just" prototypes. I suppose that using commercial 3D printing service and appropriate material would provide stronger shells, but I didn't tested things this far.
IMPORTANT : theses custom shells were offered, hence the cartridges using theses shells are not for sale and for my own collection or for friends, etc.
If you want a Gamer's Cartridge and are OK to get an Action Replay shell instead of custom one, then please check their order page from time to time and use the order form when it is available
Sorry for the clickbait title, but I'm sorry to say that it's not possible to fix your Action Replay (or any similar clone) with Pseudo Saturn Kai
Below are common myths wrongly related with Pseudo Saturn Kai : theses are detailed in this blog article in the hope it will help users with similar problems, and also to -hopefully- relieve my emails inbox regarding theses inquiries ...
Q1 : Expansion RAM no longer works ! Will reflashing Pseudo Saturn Kai help something ?
A1 : It won't change anything ! Expansion RAM is a cartridge hardware feature and consequently Pseudo Saturn Kai (software side of the cartridge) doesn't have any interaction with it.
→ If your cartridge is experiencing troubles with expansion RAM, it's likely to be related to cartridge connection or cartridge itself. So rather than e-mailing me, it's more relevant to contact the manufacturer or re-seller of your cartridge about this kind of issue.
Generally speaking, all Action Replay cartridges and their clones are using legacy electronic components no longer manufactured for nearly a decade. So even if your cartridge was sold as "brand new", it may either contain refurbished chips, or counterfeit chips, or both : there's not a lot to expect regarding quality.
Q2 : Cartridge self test feature in Pseudo Saturn Kai doesn't reports any problem : does it means that the hardware of my cartridge is working correctly ? And consequently does it means that the XYZ problem I'm experiencing is related to Pseudo Saturn Kai ?
A2 : Cartridge self test feature just tests the bare minimum of the cartridge : if it fails, then there is certainly a problem around hardware. Conversely, it doesn't means anything when no problem is reported.
BTW, I developed this self test feature to quickly test the hardware of a cartridge, and not to get a proof that hardware is not guilty when a problem happens ! It's always exhausting to read stuff like "cartridge self test passed, so my XYZ problem is caused by Pseudo Saturn Kai" ...
Q3 : I heard that game XYZ isn't compatible with Pseudo Saturn Kai ? Is that true !? Hurry up to fix that !
A3 : There are many causes of incompatibility other than Pseudo Saturn Kai :
Frequency incompatibility : Pseudo Saturn Kai bypasses game region check, but isn't any help regarding frequency compatibility : if a game was tailored to work on a PAL console, it may then not work correctly on a NTSC one and vice-versa. Simple countermeasure to this problem is to use game from same region of the Saturn where it will played on. And if it is not available then complete countermeasure is to add a frequency mod on your Saturn, or eventually to use a both NTSC and PAL Saturns for playing games of each regions.
CD-R and Saturn laser affinity : Saturn wasn't developed to play games from CD-R, which may be harder to read than official CD-ROM. So if a game doesn't wants to boot, then it's worth trying with another brand of CD-R, or to burn it at different speed etc.
Disc image dump quality : iso+mp3 format was good when downloading few tenth of MB cost time and money but is an aberration regarding compatibility. Nowadays, downloading large files is not a real problem hence bin+cue format should be considered as the bare minimum requirement that usually plays well but may cause problems with some games.
And, most accurate dumps are usually found in format supported by Rhea and Phoebe and should be preferred if you want to avoid problem(s) caused by discs badly dumped.
Additionally, I would like to remind that Pseudo Saturn Kai main role is to play CD-R backup copy of games from your collection, so if you want to ask me about the not playing iso or bin dump of the game you don't even own, then you're about to knock to the wrong door
→ First, purchase the original CD-ROM of your game, and test if it works on your Saturn or not : if it doesn't play, then supported frequency and/or hardware problem on Saturn side should be considered before asserting anything about Pseudo Saturn Kai. If the original game plays correctly it is then time to copy it on CD-R and then preserve original game preciously
Finally, it would be appreciated from users (you) to report non-working dumps to the webmaster of the page where theses were downloaded from : this would help whole community regarding preservation of Saturn games.
Q4 : Are you earning royalties from Action Replay (and
other clones) cartridge manufacturers ? If yes, then hurry up to fix my
hardware problem !
Also, I never begged any crowdfunding to develop Pseudo Saturn Kai, and even preferred to nullify my donate page
rather than receiving donation related to Pseudo Saturn Kai. You paid
$0 for Pseudo Saturn Kai to be developed ? I did it during hundred of
hours of my free time and sometimes with high doses of motivation
And while restricting Pseudo Saturn Kai usage to my own projects (USB dev cart and Gamer's Cartridge)
would had significantly simplified software architecture, I did my best
to keep Pseudo Saturn Kai compatible with other legacy cartridges so
that a wide range of users can enjoy playing Saturn. Maybe that looks
simple to do, but it's really not : the more complex the
software architecture is, the more likely development becomes difficult,
or that unexpected problem happens in the meanwhile.
So if your cartridge is experiencing a problem, it would be appreciated if its manufacturer could be blamed instead of me
This Q4 / A4 is an half-joke : so far I wasn't asked about that, but it is mentioned here to put emphasis on all the time and energy it cost to develop Pseudo Saturn Kai (I started its development at the end of 2014 !), and all the returns I have from it ("fix my flaky cartridge", "fix support for that poorly dumped game") ...
It took time, but I could find a card a bit linked to customer support from my Dragon Ball cards collection, and hope you will appreciate it ... the card, not my customer support skills
Additionally, I'm also sometimes asked what kind of cartridge is required to play Dezaemon 2 games. The answer is both simple but also a bit complex too, so maybe it would be a good idea to write about it in this blog
The simple answer is "DZ2SGM3 is compatible with any cartridge providing in-game backup memory feature". → DZ2SGM3 was developed simply as an application using standard backup API detailed by SEGA and should work with any cartridge supported by this standard backup API.
Even if I'm the main developer and manufacturer of Gamer's Cartridge, that's not a reason to restrict my software projects to this specific kind cartridge I kept support for a wide range of backup devices for the simple reason that it's cool to make more and more people appreciating games on Saturn
The complex answer comes from the two following points : - There are many kind of cartridges, and not all provide in-game backup memory - As DZ2SGM3 is not an official application, it is required for the Saturn to be able to boot applications from CD-R
Rather than writing boring theory about the internals of each kind of cartridge (is there somebody other than me interested in that ?), let's simply detail the compatibility status and the pro and cons and also the additional requirements needed to get DZ2SGM working for each kind of cartridge
① Official Memory Cartridge That's the official memory cartridge, sold by Sega during the good old times Saturn was still a commercial product. Because of that, production of theses cartridges stopped around 20 years ago and consequently cartridges available today may damage easily. The only advantage is that it's an official product, made with genuine electronic parts ... but it's now a bit too late if you want any official support for repairing a broken cartridge It's not possible to install Pseudo Saturn Kai on such kind of cartridge, so additional mod (installation of modchip or ODE) is required to use DZ2SGM.
Pro : Official product from Sega. Cons : Contents may suddenly corrupt : don't use to store important save data. Additional requirement : modchip or ODE
② Action Replay The super famous Action Replay : main advantage is from being relatively cheap, widely available, and to provide 1MB/4MB expansion memory.
Disadvantage is that technology used in theses cartridge didn't changed significantly for the last 20 years and that in the meanwhile production of this technology (flash ROM and RAM) stopped. For that reason, quality may not be at the meet even if cartridge is sold as "brand new".
In-game backup memory feature is not available for such kind of cartridge : even if advertised as featuring "4M memory card", this is available only from cartridge :games aren't able to access it. Additionally, this "4M memory card" is a bit ambiguous because it refers to the best effort when save data buffer (internally stored in cartridge 4M expansion memory) can be compressed into lower half of cartridge flash ROM = 128 KB ... if data can't be compressed then an error message will be displayed. It would had been more honest to advertise that as "Guaranteed 128KB, maximum 4MB memory card not accessible from game", but this is a bit less sexy in term of advertising
Because of the lack of in-game memory feature, it is required to use a separate backup device (such as Saturn floppy disk drive) to use DZ2SGM.
Pro : Widely available, relatively cheap, and provides 1MB/4MB expansion memory. Cons : In-game backup memory feature not supported. Additional requirement : Saturn floppy disk drive.
③ Gameshark, and other clones That's Action Replay without 1MB/4MB expansion memory and usually worse overall quality : if you have one still working, it is worth trying to use it but if that's not the case then considering for (at least) an Action Replay is usually wise decision.
Similarly to Action Replay, because of the lack of in-game memory feature it is required to use a separate backup device (such as Saturn floppy disk drive) to use DZ2SGM.
Pro : Worth using if you found a spare cartridge still in working condition. Cons : No 1MB/4MB expansion memory. Poor hardware quality. Additional requirement : Saturn floppy disk drive.
④ Memory Card Plus That's more or less a Gameshark with a specific firmware installed. Main advantage of this firmware is that it allows games to directly access cartridge backup memory.
Similarly to Gameshark, hardware quality is questionable, which makes backup memory to be easily corrupted. Additionally, backup memory capacity is around 200 KB so that it usually can't handle more than three Dezaemon 2 user games. Installation of Pseudo Saturn Kai will remove backup memory feature, so additional mod (installation of modchip or ODE) is required to use DZ2SGM.
The little side story about this cartridge is that its unique way of handling backup memory gave me the idea and motivation to develop Gamer's Cartridge Back in end of 2012, I thought only mapped memory chip could be accessed as in-game backup memory. But seeing that this cartridge was featuring only boot ROM (I tried to dump backup memory ROM, but didn't found anything there and instead there was a small firmware and save data stored in boot ROM area) made me realizing that anything could actually be shown as backup memory device to a game, which was the start point of Gamer's Cartridge project.
Pro : This gave me the idea to develop Gamer's Cartridge ! Cons : Access is not so reliable : whole contents can be wiped after writing one save there. Installing Pseudo Saturn Kai removes the memory cartridge feature. Additional requirement : modchip or ODE.
Major disadvantage is that similarly to Action Replay and official memory cartridge, technology used didn't changed significantly for the last 20 years and that in the meanwhile production of this technology (flash ROM and RAM) stopped. For that reason, quality may not be at the meet even if cartridge is sold as "brand new".
Additionally, similarly to official memory cartridge there is only limited save data integrity check available (file system is rudimentary, and only the first bytes of the ROM are check to verify if a backup memory cartridge is available or not), which is a design flaw from SEGA : it works fine in ideal conditions of cartridge correctly inserted and ROM not corrupted, but will ask to format the cartridge in all other cases. That's acceptable if you just want to copy save data (there are plenty available in Pseudo Saturn Kai Save Data Manager, so have fun with them !) and play a little to a game, but not recommended if you want to play a RPG and won't stand to suddenly lose all your progression in the game.
Pro : Both official Memory and Action Replay in a same cartridge. Cons : Contents may suddenly corrupt : don't use to store important save data. Additional requirement : none.
⑥ Gamer's Cartridge Well, that's my own cartridge project, so my opinion may be a bit biased, but it's recommended if you don't want your saves to be corrupted : as SD card file system is used, it is significantly stronger than the file system used on official memory cartridge. It is also handy if you want to backup or share your save data because exporting saves to PC can be done by simply copying files from SD card.
Additionally, it features virtual floppy disk device support, which doubles the number of Dezaemon 2 user games simultaneously available : it is limited to 5 games with other backup memory cartridges (and count may be lower because of ROM size limitation) while a total of 10 games (5 on cartridge device, and 5 other ones on virtual floppy disk) can be handled by Gamer's Cartridge.
Moreover, DZ2SGM can be accessed directly from SD card so that there's no need to swap between DZ2SGM CD-R and Dezaemon 2 CD-ROM. Major lack of this cartridge is the non-availability of expansion RAM. Also, as SD card access is not super fast, save data access is a bit slower than on other cartridges.
Pro : No risk of losing saves because of data corruption. Data can be easily backed up to PC or shared with other gamers. Cons : Limited availability. 1MB/4MB expansion memory not available. Additional requirement : none, and DZ2SGM can be run from SD card.
DISCLAIMER : play Dezaemon 2 (and other Saturn games) at your own risks ! I'm not responsible of any eventual damages caused to your save data, you Saturn, your cartridge, your dog or anything else !
SMALL REQUEST : I don't have the budget nor the free time to test DZ2SGM3 on all combinations and variations of cartridge and ODEs. So it would be very appreciated to receive feedback about if it works on your own Saturn setup
Feedback can be left by simply adding a comment at the bottom of this article : it is free, doesn't requires any kind of registration, and takes something like 5 minutes to be written ♪ In advance, thank you for the feedbacks
That's a bit late for Easter, but did someone noticed the one hidden in Pseudo Saturn Kai v6.314 ?
Easter Egg in Pseudo Saturn Kai v6.314
This can be triggered by a key combo from Pseudo Saturn Kai main menu and ODE image selection menu. It's available in both lite and full versions of the firmware and can also be triggered from RmenuKai too.
Keys sequence was changed after taking the video above, so don't try to guess it from there ! Unsurprisingly, keys sequence is more complex in Pseudo Saturn Kai v6.314
Why such kind of technical demo in Pseudo Saturn Kai ? Simply because it was fun to implement
Additionally, this is also a small wink to the good old times I was daily using a TI-89 calculator : this Easter egg was ported from Voxel2Space demo by Kai Kostack.
I still keep using my TI-89, but way less more than when I was a student. It's actually quite handy to do quick math or binary to (hexa)decimal conversions at work : the more Windows evolves, the more horrible its builtin calculator becomes (seriously, my eyes are about to bleed each time I see the Windows 10 calculator ), so it's good to have a physical calculator at reach of hands
Let's play a game with this Easter egg : the first one to find the correct keys combo will be rewarded by a Gamer's Cartridge from my own collection !
- Post the correct keys combo in the comments of this article.
- This is limited to one Gamer's Cartridge, for one lucky Pseudo Saturn Kai user.
- Don't forget to indicate an email address where you can be contacted !
This is necessary for offering the reward.
- Choice of the Gamer's Cartridge shell color etc is at my own discretion.
- Application will end in December 31st, 2019 : if nobody find the key combo until that time, I shall re-use this Gamer's Cartridge for similar kind of games with my Saturn projects.
I was recently asked about the instructions to compile Pseudo Saturn Kai from sources archive provided with Pseudo Saturn Kai binaries, so let's write a short blog article to make things clear to everyone.
The simple answer is : Pseudo Saturn Kai can't be compiled with theses sources.
End of simple answer. Those who want more details can refer to the few lines below.
Technically, some sources files are missing from source archive, preventing someone from opening sources archive, making some few changes, and installing it on a cartridge.
Why ? For the simple reason nobody won't help me if ...
Some dude takes sources, change logo and credits page and then release this as "Pseudo Saturn Kai Gold Edition made by some dude".
Some dude adds a major new feature to Pseudo Saturn Kai, and start doing business by making this firmware (and the cartridges compatible with it) available for paying. This dude will eventually forget to release any source, but who care about that except me and few other nerds ...
Maybe I would be told this I'm overthinking, but case 1 and 2 above already exist. Theses are detailed in another blog entry, and deserve a look if your time allows it.
Concretely speaking, there is one model using Pseudo Saturn sources (whose sources are fully available, and with build instructions too), hacked to don't show any startup menu (why not would you say, it's more convenient for the consumer), and consequently not showing any credits nor any mention it was made from Pseudo Saturn ... why not would you say, but that's a massive NO for me, and the Pseudo Saturn team will certainly not appreciate that too.
Some other projects are using fancy case and label instead of Action Replay ones (I'm OK with that, especially because Action Replay design guidelines are completely outdated), but don't mention anything about Pseudo Saturn Kai on their covers and labels until booting the cartridge and discovering ... a vanilla version of Pseudo Saturn Kai without any mention of the fancy product name advertised on the cartridge box and label I'm sorry for the consumers who were expecting firmware design to be unified with cartridge box and label : this wasn't done because some few files are missing in Pseudo Saturn Kai sources !
This case of "some people are making money from rebranded homebrew projects" is also detailed on Segaxtreme forums, which deserves a look if your time allows it.
The thread there is not by me, nor about Pseudo Saturn Kai, so I hope how real the fact is that there are people making money from other people's hard work ... that's maybe normal in any work place (), but that's a dick move in such a small Saturn homebrew community.
To sum up the bulky paragraph above, the way of sharing Pseudo Saturn Kai source code is not how it works in free software world.
In an ideal world, everybody share source code, and everybody other make contributions, and the project is getting brighter by brighter. So if the story stops here, I'm the bad one, but in real world, people deface the credits page, rebrand the projects under fancy names and start making cash and show business from projects they didn't contributed on ... Maybe it's selfish from me, but I don't want that and consequently removed few files from Pseudo Saturn Kai source code.
And if I may add an additional paragraph about Pseudo Saturn Kai, I would like to say it is quite open in the magic world of application to play games on Saturn real hardware : modchips are completely closed-sources, ODE too. In Pseudo Saturn Kai, the sources of the exploit to play CD-Rs, as well as the ones to redirect memory devices to SD card are available. The source code of the implementation of cheat codes engine is available too. I coded it from scratch because sources of Action Replay firmware are not open source ...
To add a bit of melodramatic taste to this blog article, I would like to say I spent the last four years developing Pseudo Saturn Kai.
I didn't asked for any payment about it. The next day after I received a $5 donation for it, I changed my donation page from "send money here if you want" to "send me kind message or a comment on my blog".
I didn't begged for any kind of crowdfunding too, and just wanted to continue the project where CyberWarriorX left it.
While four years seems a long period for just two or three features, you probably may want to look at Pseudo Saturn Kai credits page, and all the people who contributed to it. Theses two or three feature are not the kind of thing someone develop, test, re-test, fix, and keep testing more and more during a weekend. From my own experience, normal people don't continue development so far and just give up development after a couple of weeks. And, I won't appreciate this credits page to be defaced. Not for my nick to be removed (I'm listed there only one time), but for the respect to all the contributors being lost.
And while I developed custom cartridge using Pseudo Saturn Kai, I kept support for Action Replay cartridge and their clones. That may sound obvious, but technically speaking it isn't, mostly because Action Replay have limited ROM size. At some point of Pseudo Saturn Kai development, I hesitated to put cheat codes feature in a ROM portion larger than current one, but unavailable from Action Replay cartridges. This would had made more cheat codes available, but the feature itself usable on Gamer's Cartridge only. I choose to keep a reasonable size for cheat codes list, so that it would be available for everyone on Action Replay cartridges
Words count for this initially expected "short" article is about to reach four digits soon (it's 827 words now), and as I doubt a lot of people will read it entirely, it's probably time to conclude :
No full sources for Pseudo Saturn Kai
If you want to make you own Saturn cartridge firmware, then feel free to use Pseudo Saturn sources as a starting point.
Feel free to technically refer to Pseudo Saturn Kai source code, and to merge whatever you find interesting there to your project.
Still begging for Pseudo Saturn Kai full source code ? No problem, I shall make it available to everyone ... if there's not a physical disaster on my dev laptop or its SSD in the meanwhile.
At that time, this will definitely be the end of Pseudo Saturn Kai development. For you, and for me too.
Just a small article to wish an happy birthday to Pseudo Saturn
I'm not sure about the exact birth date of Pseudo Saturn, but it seems to be around July 7th, 2014 as it was announced on Assembler Games forums at that date. The first commit of source code was on the next day, and as contributors of this projects are spread around several time zones, it's difficult to give an exact birth date.
It is July 6th here, so I'm one day early to wish happy birthday to Pseudo Saturn, but as I will busy at home tomorrow (with non-Saturn things), and busy at work the day after tomorrow (with non-Saturn things too), it's better to wish this now than three months late
Now that I realize this project is already 5 years old, I feel a bit old But as at the moment of Pseudo Saturn initial release I was waiting for my turn of heavy surgery, it's cool to be alive 5 years after theses dark days for me
It's not an "I'm tired to continue that" farewell nor an "Everything is perfect in this project, so it should stay eternally as-is"; in fact Pseudo Saturn Kai was a reason to live (even if chemo is painful, or scars from surgery are hurting, or dudes at day work are boring), so I don't have plans to dump this project in a near future But on the other hand, I would like some extra time for other projects : I shall return back to Pseudo Saturn Kai development if theses other projects fail, or when I will miss the good old smell of Pseudo Saturn Kai source code
I was a bit in lack inspiration when choosing a closing picture, so please enjoy one about Vegeta from my collection. I choose another picture of Vegeta in recovery machine as profile picture when registering on AG forums 5 years ago, to wish me a good recovery during relatively long (expected 3-5 weeks, but it latest 7 for me) hospitalization ... I'm still here so maybe it wasn't a bad choice
I sometimes have several nice stories about hardware/firmware/software development experiences I would like to develop on this blog, but when comes the time to write it's usually annihilated by ...
The lack of free time : my "free time" for Saturn is usually one hour or two in the early morning, or a similar duration during night
The lack of financial support : while Pseudo Saturn Kai kept me busy for around 5 years (I started by developing firmware flasher in August 2014, to then start developing my own Kai firmware from the following year), I only received 5 US dollars for it. Maybe it would had been smarter to do more aggressive show business about my Saturn projects to get more money from crowds, but while I consider development as a funny activity, show business isn't : bragging about some project super cool but shall be finished someday is not for me. I prefer to directly try finishing theses unfinished projects instead
The lack of motivation : after writing an article here, that usually ends in ... - People commenting, but about a Pseudo Saturn Kai setup trouble on their clone cartridge usually not related to the blog article it was commented from. - People commenting, but about requiring about unrelated XYZ feature in Pseudo Saturn Kai, or any kind of technical collaboration that I should definitely volunteer on. - Nobody commenting : I personally consider this is as the best option because at least it doesn't requires me to spend time writing any reply.
Okay, here is just a flaky blog about B-rank homebrew projects made by one random dude on a vintage video games console, so who care ? But whatever it may be, I continue unidirectional writing here in order to get fun stories to tell to grandchildren in the future
Back to the main topic : no motivation and no time for this blog. As a countermeasure let's write a short article
As indicated on the title, this is about installation videos of Pseudo Saturn Kai ! For the "no time and motivation for show business" reasons detailed above, I personally don't had time to do any kind of video, but Retro Sim was kind enough to prepare one
Pseudo Saturn Kai v6.314 installation video
I hope this video showed how easy to upgrade from an older version of Pseudo Saturn Kai to latest one : that's just the matter of burning a CD-R, to boot it in the same way as your favorite game, and to follow instruction displayed on screen !
The only difficult part during installation of Pseudo Saturn Kai (for example from Action Replay stock firmware) is that it requires usage of CD swap method to make setup CD-R booting correctly.
This is however not necessary when installing over an older version of Pseudo Saturn Kai, so there are no excuses to use outdated version of Pseudo Saturn Kai
This latest v6.314 flavor of Pseudo Saturn Kai was made with my heart, blood and tears as the previous ones, so I hope it will contribute to make Saturn more and more appreciated
There aren't major feature addition from previous (6.274) version, but cheat codes support was a bit improved and all control pads including third party ones should be now correctly supported. And as usual, it's free (like in free beer) to use
As indicated in the title : I'm glad to announce the release of Pseudo Saturn Kai v6.374 ! It is available for download at the usual address on my homepage.
This time, there aren't any "big" feature added, but rather a streak of small fixes as well as few minor improvements too. So don't wait to upgrade your cartridge and enjoy even more your favorite games with Pseudo Saturn
What's new :
Show error message when SD card is not inserted into Rhea/Phoebe ODE.
Added RmenuKai : enjoy cheat codes on Rhea/Phoebe even without cartridge !
Improved compatibility of JHL loader-only games with Rhea/Phoebe ODEs. (Panzer Dragoon Saga can now be correctly loaded from Rhea ODE)
Improvements in automatic selection of game in cheats codes feature.
And there's also a small Easter egg hidden in some menus ... will you be able to trigger it ?
What didn't changed :
Plays games backed up on CD-R, without the need of any hardware mod.
Comes with a bunch of pre-installed cheat codes.
Provides image selection menu for Rhea and Phoebe ODE.
Available for free and for everyone : it doesn't costs any license to install, and I didn't begged any money to develop Pseudo Saturn Kai too.
This version was thoroughly tested by same beta testers who followed development from last public release, but on the other hand it was tested by ... nobody else during beta testing phase ... this is probably a fault from me (it was announced for one week on segaxtreme forums, and ... for one day on this blog), but today is the third anniversary of initial release of Pseudo Saturn Kai as well as Gamer's Cartridge so I didn't wanted to miss this occasion
So don't worry and happy playing ! I spent last 5 months in developing this version, and my favorite beta tester spent the same period in testing around twenty beta builds so it will run fine on your Saturn ! Trust me, I'm an engineer
Not my favorite PCB,
but at least it works.
It's time to pick up the kids at their Monday evening activities but I still have many tidbit stories to relate about ! So please stay tuned in future article(s)
Edit (2019/06/10) : it should be a good idea to add links for discussions on external sites :
Once upon a night, I wanted to verify Pseudo Saturn Kai products lineup and realized PRO edition was recently added !
The PRO edition itself was based on same technology as lite one, but requiring a small subscription (in one-digit dollar range) in order to allow installation. In other words, the same contents as lite (free of charge) edition, but financially supporting firmware development and maintenance costs.
Pseudo Saturn Kai PRO edition was so popular that it was attracting enough money to cover my daily personal expenses and at some point it was even enough for apartment rent as well as family's cost of fuel and light ! On the other hand, Pseudo Saturn Kai PRO edition support team was greedier and greedier about new features, visual improvements of the firmware's UI, and the longer it went the more oppressed I was to maintain Pseudo Saturn Kai code base.
And then, the poor man's alarm clock (= in simpler words, light of the morning sun) woke me covered in sweat and experiencing high heart pulsations.
I had to verify this was a nightmare ! ... But before that it was time to start the day with laundry, because procrastinating the laundry duty delays all the subsequent tasks after that until the end of the day
So during my earliest spare moment during that day (somewhere between 6:30PM and 7PM), I could verify that everything was normal regarding Pseudo Saturn Kai project : the lite version free for everybody, and the full version also free but usable only in my hardware projects.
So no deadline, no pressure, and no impatient users ! I was relieved because I have enough of that at regular work !!
On a more serious note, I'm glad to announce that release candidate version for next release of Pseudo Saturn Kai is ready !
This RC version was thoroughly tested by same beta testers who followed development from last public release, so the risk of bricking cartridge or facing bugs bigger than an elephant are quite low.
I'm however not confident about usage in unusual configuration, so that I would like it to be tested by a few more people for my peace of mind before putting it on the wild.
On the other hand, if you just want to use latest version and don't plan to give testing feedback, then please *don't* contact me and wait patiently for one week or two until RC version becomes publicly available.
What's new in upcoming next release : basically there aren't new major feature available (like cheat codes in previous v6.274 release), but enough changes and/or improvements to make everybody wanting to upgrade.
Show error message when SD card is not inserted into Rhea/Phoebe ODE.
Added RmenuKai : enjoy cheat codes on Rhea/Phoebe even without cartridge !
Improved compatibility of JHL loader-only games with Rhea/Phoebe ODEs. (Panzer Dragoon Saga can now be correctly loaded from Rhea ODE)
Improvements in automatic selection of game in cheats codes feature.
And there's also a small Easter egg hidden in some menus ... will you be able to trigger it ?
To shortly sum up the changelog, Rhea/Phoebe ODE users will be happy to find that this release will allow usage of cheat codes without the need of any cartridge And some Rhea users shall also appreciate Pseudo Saturn Kai finally loading Panzer Dragoon Saga correctly.
There are also some fixes and improvements around cheat codes (available for everybody, not requiring ODE or any special cartridge) and I sincerely hope theses will contribute to make more people enjoying playing Saturn
Rare footage of Pseudo Saturn Kai development room.
I really like Jean-Luc love for DIY work, as well as his aversion for things too make-up to be real. Everyone should be proud of their own work rather than being a simple consumer (not to say stubborn believer) of someone else's work
As indicated in the title, I wish you an happy new year for 2019 !
Did you decided about your promises for this new year ? Personally I didn't and just plan to continue having fun with my Saturn
And, I hope that the new freshly released Pseudo Saturn Kai bringed you even more fun with your beloved Saturn If you want more rings for Sonic, or doing off-track tourism in Sega Rally without minding about remaining time until next check point, this is now possible thanks to cheat codes feature
In an unrelated note, it's funny to notice that people pre-flashing Action Replay cartridges had short winter holidays, because Action Replay with new logo on label were found around one week after Pseudo Saturn Kai release
The design is questionable : why such aspect ratio for the logo ?! I guess it's to see it when cartridge is plugged, but I personally think it's a bit too "stomped" Anyway, that's still better than the original Action Replay logo !
but I hope that everyone spent a nice Christmas and are appreciating winter vacations 
Without privateye, Pseudo Saturn Kai certainly wouldn't had its edges polished so well 
) is empty and that I found the time and motivation to write this article, it's time to officially put Gamer's Cartridge project on pause.
) so I don't want to hear any kind of price reduction after that. If you want a cheap cartridge, the red "all-in-one" cart is all for you.
