Dezaemon 2 Save Game Manager 3 : test on CD-R

Written by cafealpha no comments
As indicated in the title of this article, I tried to verify if Dezaemon 2 Save Game Manager 3 (DZ2SGM3) is working correctly from CD-R on an unmodded Saturn.


Dezaemon 2 Save Game Manager 3 (Beta v6.212)

The reason this video was taken is that somebody contacted me to know if DZ2SGM3 works correctly with an "all-in-one" ©®TM red cartridge. But as I don't own such kind of cartridge, I did my best with the few things I can use here.

Initial goal was to test public version (v6.274, 2018/12/28) with official memory cartridge on Saturn with modchip installed, but ...
  • My modded Saturn was buried too deep in my closet; I was too lazy to exhume it ...
  • The CD-R on which I burned public version of DZ2SGM3 didn't wanted to be read from Saturn; I was too lazy to re-burn it ...

So this ended in testing on an unmodded Saturn with Gamer's Cartridge  I couldn't test it by myself, but I'm confident DZ2SGM3 can be used on official memory cartridge and on "all-in-one" ©®TM red cartridge too. "It works, trust me I'm an engineer !"

I did my best to develop DZ2SGM3, but as of a self-produced project (developed on my free time, didn't begged any money for it and on the contrary, I pay my homepage provider to host it), I don't have the budget nor the time to test on all combinations of backup memory cartridges and modchips/ODE/Pseudo Saturn cartridge/whatever with this application.
So if someone is owning an "all-in-one" ©®TM red cartridge and appreciating shooting-up games, that would be cool to receive some feedback about DZ2SGM3 compatibility in the comments of this article



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.


⑤ "all-in-one" ©®TM red cartridge
That's the equivalent of Action Replay and official memory cartridge blended in a single PCB. Main advantage is to feature theses two cartridges in a single one, which is convenient for playing a wide range of games.

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

Pseudo Saturn Kai v6.314 : Easter Egg !

Written by cafealpha no comments
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 !

During the last years, I was gathering Gamer's Cartridges with custom 3D printed shells and PCBs from various production batches and different times of the development of the cartridge.
Rather than just putting on sale, theses are kept for good occasions, and finding this keys combo is one of such kind of good occasions
Custom cartridge shell .
Thanks to zone66x for designing
and printing them


Rules :
 - 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.

Pseudo Saturn Kai v6.314 - The newer the better

Written by cafealpha no comments
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.
  • Improvements regarding Virtual Memory Cartridge automatic settings.
  • Fixed support for some third party wireless pads.
RmenuKai for Rhea/Phoebe : test with cheat codes for NiGHTS
If you prefer hedgehogs, there is also a similar video with Sonic 3D.


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 :

Pseudo Saturn Kai PRO edition - RC1

Written by cafealpha no comments
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 !!

~ Development of Pseudo Saturn Kai PRO edition ~
By Mr Quino, from Mafalda  #1212


"Wow, look at what I saw in the newspaper :
a millionaire died from overwork !"
"Yeah, there are such kind of stupid people who
get accustomed to millions and then can't stop."


"And they want more ! Again !"
"Again ! Again millions !"


"Again ! AGAIN ! AGAIN !"





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.

So if you are volunteer for testing (and reporting me testing results) please contact me by PM on segaxtreme forums, or by email from my contact page.

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.
  • Improvements regarding Virtual Memory Cartridge automatic settings.
  • Fixed support for some third party wireless pads.

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

Various Pseudo Saturn cartridges

Written by cafealpha no comments
Long time no see ! It's a super long while I wanted to write about several kinds of Pseudo Saturn cartridges (other than the usual Action Replay/Gameshark couple) but as a lot of things in this blog, always postponed it.

But recently I discovered a cartridge that breaks all records in term of extra cheap design and appropriation of other people's work that now I really want to terminate this article

(Note : it's already 10 13 14 29 days after the creation of this article, and it is still not published yet ... but I do my best to finish it )


Disclaimer : I am not affiliated with the designers or developers or sellers of the cartridges below. The reviews below are just my personal opinion and may not reflect the exact contents or behavior of the cartridges. And in case of questions regarding theses cartridges, please contact their sellers instead of me.
Also, please try theses cartridges at your own risks : whatever it may be, I'm not responsible about any damage caused to your Saturn, your cartridges, your dog, your house or anything else !

And let it be clear : the first purpose of this article is to inform users that such kind of not so usual cartridges exist, so that potential users can consider about theses cartridges for their own usage.
But if a cartridge deserves to be flamed, then I don't refrain about that, especially when it concerns the appropriation of other's people work.



Saturn NinjaDrive


From what I could see, that's an Action Replay cartridge with custom label and Pseudo Saturn Kai pre-installed. The "deluxe" edition features a stylish box for the cartridge.
It probably would had been appreciated to indicate that Pseudo Saturn Kai is installed rather to rebrand everything under a different name ...

Pros :
 - The price without stylish box is not that bad
 - Pseudo Saturn Kai is pre-installed
Con :
 - It would had been fair to indicate that cartridge is made from Action Replay cart
 - There's no indication about which firmware is installed



Saturn Unlocker



That's in the same range of contents (and price) as NinjaDrive : Action Replay with Pseudo Saturn Kai pre-installed. At least there's no attempt to hide about what is installed.
A description video at the lower half of the cartridge's page shows that Pseudo Saturn 0.832 is installed, which doesn't works at all on some Japanese model 1 Saturn The video itself is quite old, so let's hope that latest version of Pseudo Saturn Kai is installed on the cartridges now

Pros :
 - Classy box and label, a must have on your collection shelf
 - Pseudo Saturn Kai is pre-installed
Con :
 - It would had been fair to indicate that cartridge is made from Action Replay cart
 - Maybe a bit expensive ?



All in One RAM Backup Cartridge


All in one cartridge, front side.
Picture credits : SaturnGuru.

I couldn't find an official homepage for this "all in one" cartridge, but this is paradoxically the most valuable cartridge in this article
This cartridge model features both Action Replay support (boot ROM and 1MB/4MB expansion RAM) and 512KB backup memory storage. In simple words, it is the result of Action Replay and official memory cartridges blended together.

The backup memory is implemented with its own flash ROM chip, in the fashion as official backup memory cartridges, thus shall provide a 99% compatible (I keep the last 1% just in case of any eventual picky game that would cause problem, but this would be surprising such one exist) and in-game support for cartridge backup memory.

Using dedicated flash ROM for backup memory unfortunately means that it will be corrupted and finally no longer accessible after many write cycles, but ... this is how official cartridges worked too
However, since boot ROM and backup memory are stored in physically different flash ROM chips, the cartridge will still boot Pseudo Saturn Kai even if backup memory chip is damaged, which is one point over Action Replay where damage of backup memory ROM means the loss of nearly all other features.

Regarding firmware installed, the ebay pages selling this cartridge model I could see so far clearly mention that latest Pseudo Saturn Kai version (v6.074 at current time) is installed, and even explain the basis regarding cartridge usage such as loading a game, or accessing Save Data Manager, etc, which is quite a fair and remarkable way of doing

A review with only praises may look a bit biased (and no, I didn't received any money nor even any email from seller of this cartridge), so I would like to critic about the electronics parts used in this cartridges : theses are the same as used in Action Replay or official backup memory cartridges.
As a consequence, the technology used is no longer produced, thus probably coming from shady old stock, or counterfeit chips factory, or recycled from vintage devices. In each case, this means that in the long term, quality may not be at the meet.


An interesting related question is "Why releasing such cartridge around 20 years late ? This could exist at the time Action Replay cartridge development was still active !".
My guess about this question is that Action Replay development and/or sales team wanted to put everything (boot ROM and cartridge memory) in a single flash ROM chip, giving birth to the "if a ROM feature breaks, the whole cartridge is bricked" cartridge architecture used in Action Replay carts.

I personally like to write to flash ROM only when upgrading cartridge firmware, so that I dropped backup memory support on Pseudo Saturn Kai lite.
So my second guess is that it motivated someone to finally merge Action Replay and backup memory cartridge in a single one ? If this guess is right, then I'm glad to have indirectly contributed to the development of this cartridge

And yes, I am the only one responsible of this backup memory feature no longer available after installing Pseudo Saturn Kai. That's a deliberate choice to avoid cartridge bricking and I will never add a feature for that, so don't hesitate to share your hate towards me in the comments of this article 


As an extra note, I could notice that several hardware variation for this cartridge model may exist, so anyone interested in purchasing such "all in one" cartridge should carefully verify it's item description page as well as features list indicated at the back side of the cartridge.

And finally, please enjoy a picture of each sides of the cartridge PCB Theses pictures clearly indicate how the cartridge works, and were a great help when preparing this article.

Pros :
 - Supports basically nearly all the Saturn games library
   (Except the couple of games requiring their own ROM cartridge, and those others eventually not compatible with Pseudo Saturn Kai)
 - Pseudo Saturn Kai is pre-installed
 - There's no attempt to hide that Pseudo Saturn Kai is installed
Con :
 - Cartridge backup memory may deteriorate after heavy usage.


Edit (2019/01/09) : there is also some kind of "dual boot" cartridge that seems to allow to select among two firmwares which one to boot.

Saturn PASS

You're full of all theses cartridges to digest in a single article ? That's bad for you, because I kept the most greasy dish for the last time

Saturn PASS cartridge

This is a very simple cartridge with only boot ROM, and nothing else : no cartridge shell, and not even decoupling capacitors near the ROM chip ...
The decoupling capacitors protect neighboring components against voltage spikes : as theses apparently don't have any functional purpose, they are sometimes removed by cheap device cloners ...

Additionally, ROM chip used seems to be a UV EPROM, easily identifiable with the small round window at the center of the chip.

UV EPROM chip detail
Yes, I did hit the snapshot key around 10 times to get
the right moment when UV window is visible
(Screenshot from this video)

As a consequence, firmware update requires dedicated device to illuminate the chip with UV light prior writing of the ROM and basically can't be easily done on user side.

Additionally from being technically difficult to upgrade, Saturn PASS users will also have to enjoy the custom firmware pre-installed : apparently it's a stripped version of Pseudo Saturn (or it will be an huge coincidence that log message under "Loading CD" is the same in both firmwares) with only the bare minimum remaining :
 - No boot menu
 - "Pseudo Saturn" name changed to "Saturn PASS"
 - Addition of URL to Saturn PASS homepage
 - Removal of Pseudo Saturn credits

Saturn PASS boot screen
For unknown reason they left as-is the
log display in is_audio_cd function.
(Screenshot from this video)

Pseudo Saturn is open source, so anyone with enough skills is free to change things in the firmware to their preferences. But rebranding the whole thing and trashing credits to original development team is not how open source works.
So if someone wants to thank somebody for Saturn PASS to exist, they should refer to credits displayed in Pseudo Saturn :
Copyright 2011-2015 Pseudo Saturn Team
http://github.com/cyberwarriorx/pseudosaturn
At a glance, removal of boot menu and only keeping the Pseudo Saturn exploit sounds a good idea, because that's one step less to do on user side before playing a game.
But except that point, it's complete crap : extra features (to verify if cartridge is working correctly or not, or to verify version of Saturn internals, etc) are no longer available, as well as credits page too.

Personally, I derived Kai from Pseudo Saturn specifically for adding features other than Pseudo Saturn exploit : memory cartridge support in previous releases, cheat codes in next release(s), and probably something more in future release(s). So removing all the menus and extra features just to spare the push of one button to play a game is "no, I won't do that"

Pseudo Saturn Kai credits page is probably just a feature to boost my own ego, but I am not the only one listed there, and everybody credited contributed for free : done on their free time and without financial compensation. So muting them is definitely not an option. Also, I made several graphic improvements when displaying credits, so I hope you will enjoy them in next release

To finish on a positive note about Saturn PASS, it should be mentioned that its price is relatively reasonable : 350 Thai Bath = around 10 US Dollars, which makes this cartridge affordable for Thailand users

Pro :
 - Affordable for Thailand users.
Cons :
 - Poor hardware design.
 - Can't upgrade firmware.
 - No credits to original firmware developers.

PS : I heard about this cartridge from furrtek. Special thanks to him for the information
