Today is some kind of special day for me : among many other things, this is the anniversary of Jean-Luc Le Ténia
, the best French singer in the world
! Jean-Luc would had be 45 years old today but unfortunately is no longer here to celebrate today with us.
Today is also the 4th anniversary of Gamer's Cartridge
initial public release. For more than three years, this project was the occasion to meet many people, to loose hair on many bug and -I hope- to have contributed in a better Saturn community
Jean-Luc Le Ténia is no longer here, Gamer's Cartridge production was frozen (not to say discontinued) last year because of enough free time lacking to assemble new cartridges. And Saturn gamers are now either using Action Replay (reliable expansion RAM but no backup memory) or "all-in-one" cartridge (backup memory but sometimes buggy expansion RAM) to play their favorite games.
To makes things a little brighter, the best I can do is to develop a new Pseudo Saturn Kai fitting more nowadays needs and situation :
- Built-in support with latest ODEs
- In-game save data access for Satiator ODE
- Save data storage on cartridge flash ROM
As a consequence of my free time being limited from this year, I thought in stopping non-priority projects to focus on other (not necessarily Saturn) ones. But on the other side, if I don't improve Pseudo Saturn Kai, I'm not sure that somebody else would do it for me !
So if the Saturn community shows enough interest, I would like to contribute to a newer Pseudo Saturn Kai
And to measure if the community is interested or not, I'm making Pseudo Saturn Kai development crowdfunding-based.
Principle is simple : the more interest (support) from the community, the more free time I allocate on Pseudo Saturn Kai. And the less interest from community, the more free time I spend on other projects.
I don't plan to make a living in developing Pseudo Saturn Kai, and for this reason all the development made so far was done on a altruist basis.
All the development made so far (cheat codes, Rhea/Phoebe support etc) was cool but honestly a lot of work. So with your help I would like to find enough energy to give it birth again

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 !A4
: I don't earn anything from
legacy cartridge manufacturers : you paid $35 for your Action Replay
cartridge ? I received $0 from it. You paid $60 for a red "all-in-one" ©®TM
cartridge ? I received $0 from it.
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

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".
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.

The kids are currently on winter holidays, I don't want unexpected and messy task at work before entering new years holidays, so today was spent at movie theater with kids
We went to see Dragon Ball Super - Broly
, and it was cool !! I really appreciated the "フリーザー！「カコク」ってなんだ！？" from Goku just after Freezer used "過酷" word in a dramatic scene
So well, it seems it's the good moment to announce a new public section in my homepage, which is about Dragon Ball cards
More than 15 years ago (but it feels like last week ... I'm really getting old !), I spent many afternoons in scanning my collection of Dragon Ball cards, and then put everything on a CD-R ... because internet was paid for each minutes connected, and my maximum transfer speed at that time was around 7KB/s, hence not suitable for uploading hundreds of megabytes of data
All theses limitations are no longer a problem, so please enjoy my digital cards collection
Broly when I was a kid
Oh, I forgot to say that everything in more or less in its original state, including the html, so in advance I'm sorry for any reaction to Comic Sans MS font and flashy image background
Also, the textual contents are left as-is in omelette du fromage
there's currently a bug so I shall re-release it soon
After everything will be fixed and verified, I shall make a proper announcement in this article, so if you don't want to flash your cartridge twice, please keep tuned for one day or two !
: version v6.274 was released a couple of a days ago
, and so far I didn't received major claims about it, so let's consider this version a stable one ! Please find below an overview of the changes and additions in this release.
What's new in Pseudo Saturn Kai v6.274
Automatic Game Loader
So far in Pseudo Saturn Kai 6.074, user had to choose which game loader to choose before starting a game, but this is now done automatically on Pseudo Saturn Kai side.
There's no magic around this feature : it just uses a list of games not compatible with CWX loader, and decides accordingly
Pseudo Saturn Kai boot menu
No need to worry about which loader to choose ♪
That's a big addition for this release. Its development spans around June 2017 to Spring 2018.
The main features for cheat codes are :
- Built-in : don't need to manually enter the cheat codes
- User friendly : just push X button when booting a game, and then select the cheat(s) to enable.
- Maintained by cafe-alpha () : rather than adding an "enter cheat codes by yourself" feature, I plan to continue improving and maintaining the cheat codes list
Back in 2015, I added a stub of alternate rmenu to Pseudo Saturn Kai, but didn't had the technical information regarding Rhea/Phoebe API so the feature was disabled in its unfinished state.
And this summer, an enthusiast friend
helped a lot to get this technical information, so that I could finally finish this feature
Development of this feature was an occasion to bring usage of proportional font in image selection menu, thus showing more information on a single screen. Base of menu module was developed around 2010 without any consideration for proportional font, so development of this side feature was a nightmare, but I don't regret for having done it now it is finished

Dezaemon 2 Save Game Manager 3
Dezaemon 2 is a shooting game maker application for Saturn. And Save Game Manager is a collection of user games for Dezaemon 2.
By the past, there were two volumes released by Madroms : SGM1 in 2007
and SGM2 in 2008
And 10 years after that, SGM3 is released and contains some new user games as well as all the games from SGM1 and SGM3 : one SGM to rule them all
Special thanks to Dezaemon DB
for gathering a community around Dezaemon 2, and dumping the user games

In-game connectivity for USB dev cartThis uses cheat codes routine, hence requires at least a valid master code to be set. It can do USB connectivity while doing transfer with PC, but that's a bit slow (because of unoptimized C running from cartridge ROM), and consequently may cause glitches on some games.
As a countermeasure, there is another mode who does only USB connectivity (hence no cheat codes) but does it fast since the code for it is written directly in assembly and running in RAM.
That may be cool for game hacking, or looking for new cheat codes ... but I still need to add a proper cheat codes finder feature on SatLink before looking for cheat codes on my favorite games
In-game USB connectivity in action.
Radiant Silvergun was one of the very first games
to work correctly with Pseudo Saturn Kai cheat codes
Virtual Memory Cartridge support via USB dev cartThis is similar to "Virtual Memory Cartridge" used in Gamer's Cartridge, but access save data files on PC via USB dev cart instead of SD card.
That's convenient for save data hacking, or testing several saves, but for normal use then using SD card is (in my opinion) a better choice.
As a consequence, full firmware can now be installed on USB dev cart. But cartridges not using SST39SF040 flash chips are not supported (because there's not enough room in flash ROM) and in that case only lite firmware can be installed.

Fixed support for 3D padIn previous version, using 3D pad would sometimes cause an emergency exit to multiplayer screen when touching analog buttons. This is now fixed, and additionally supports input from analog buttons.
Pseudo Saturn Kai is not a 3D game, so the interest of using analog buttons is a bit questionable, but at least it is supported now
And the most voluminous change is ... :Fixed many bugs everywhere, added other bugs here and there
Everything should work now ! Trust me, I'm an engineer
Congratulations, you reached the end of this long article
Last but not least, I wish you a Merry Christmas, happy new year 2019 and happy gaming

... and all of a sudden, November arrived
It's not like being under a quota of articles to write every months would stop the financing of my Saturn projects and in fact, as described on my "donate
" page or this blog article
, I don't have any interest in crowdfunding, or some kind of third party financing : if I'm not in the mood, or don't have enough free time to update this blog, then I don't update it
But well, moreover not being paid for not writing blog articles, as I actually have to pay to keep this blog alive (web page hosting is cheap but not free, but at least it's my own homepage
), I like to feed this blog from time to time even when being busy with real life things
So don't worry, I didn't stopped this blog : currently, I have one ongoing article that is waiting for its last paragraph and proofreading etc, but as I started more than two weeks ago (yes, that's my usual pace when preparing blog articles), please be patient until I finish it
I do have some ideas for future articles too, but theses are just ideas currently recorded as single lines in my TODO list, so I don't know when I actually start writing them
Regarding Pseudo Saturn Kai project, I ... didn't had a lot of free time to continue it recently
In fact, I think I just turned on my Saturn once last month just to test if -as requested by someone by email- DoDonPachi worked with Pseudo Saturn Kai or not. The game worked fine here, so I turned off my dev Saturn an put it back in my closet for better times when I will be more available
BTW, I'm currently experiencing an unexpected burst of things to do at work, so it may take a while until things return back to normal
But as I can't live without doing my Saturn projects, I promise that things will return back to normal as soon as possible
... Well, the contents in this article are a bit poor, so let's fill remaining space with random facts about my life recently
The "okra" plant I wrote about in a previous blog article
is still going well and I continue to water it regularly.
Okra in all its glory, 2018/10/18
Since summer is now finished, I no longer have to water it everyday, so that I now just do this regularly enough to prevent it from finishing yellow and burned
And yes, the kid who took back that from school completely forgot about its existence
I'm not keen on gardening (as suggested on the picture above, I don't even own a garden), but have a couple of pictures of other green things in reserve ... and I keep theses to fill future small posts
