Hey guys here is a simple mod i have done to my Action Replay 4M Plus cartridge so i can dual boot the Action Replay firmware as well as the Pseudo Saturn Kai Lite firmware or a different firmware, For anyone interested here is the guide i've done.

This guide is for Action Replays with 2x 29EE020 eeproms, Board may look slightly different to mine.

Why do i need this?
If you're looking to get Pseudo Saturn Kai or try some other firmware and already own an Action Replay 4M Plus or you have already flashed Pseudo Saturn Kai Lite to your Action Replay 4M Plus then this maybe of interest to you, With this mod you will be able to flash/reflash the Action Replay firmware to your cartridge and then using the switch flash Pseudo Saturn Kai Lite or something else to it as well and then have the ability to switch between the two so you have the benefits of both.

For anyone considering performing this mod, please note that @cafe-alpha has recently launched a Patreon campaign to support new versions of Pseudo Saturn Kai, and one of the planned features is backup memory storage for Action Replay cartridges. If this feature gets implemented, this mod won't be necessary for most users.

If you would like to see this (and other cool features) in Pseudo Saturn Kai, please consider pledging your support :)

lol you really have no idea

Care to elaborate? I didn't mean to cause offense as this is a cool mod but, for most users, it won't be necessary when the new firmware comes out. The whole point of this mod is to combine the features of Action Replay stock firmware (save data manager) and Pseudo Saturn Kai (CD-R support). Once PSK has a save data manager of its own, there won't be much need for Action Replay stock firmware unless you want the ability to add/edit cheats.

cafe_alpha has already stated the whole reason he didn't implement save support is because there's a chance it could corrupt PSK and prevent it from working and the only save data manager that is included and will be expanded on is for PSK on something like the Gamer's Cartridge which allows saving to sd card.
also the main reason for this mod is to allow you to keep the action replay firmware in tact whilst still being able to have PSKL on it, as well as being able to use the cheats etc.

I am aware of his stance about that, but @cafe-alpha plans on adding backup memory storage for Action Replay cartridges in Pseudo Saturn Kai Lite, if his Patreon campaign gets enough support. Here is an excerpt from his Patreon:

For several years until now, my goal for Pseudo Saturn Kai was to provide an affordable and non-invasive mod to play Saturn games.
I consider this goal being complete but there are still some "side quests" remaining :

- Add backup memory storage feature for Action Replay cartridges
- Add in-game save data support for Satiator Optical Disc Emulator
- Improve support for Optical Disc Emulators

that could be a long way off, if he decides to go through with it and it works to a point where he's comfortable releasing it but that could be a long way a way so for you to come here and advertise someone else's thread and patreon is rude at best and you're making out like that feature is coming soon when in reality it may never come you just don't know.
plus this mod isn't just for pseudo saturn kai lite, this mod will let you dual boot any two firmware that will fit on the flash chips.

I'm sorry that you took offense. My intention was to inform people about an alternative option (if the feature eventually gets implemented) for anyone stumbling across this thread, so with that in mind I would say I was being "helpful at best, rude at worst".

...and you're making out like that feature is coming soon when in reality it may never come you just don't know.

In my previous post I said that this feature will come "if his Patreon campaign gets enough support." The key word being "if".

plus this mod isn't just for pseudo saturn kai lite, this mod will let you dual boot any two firmware that will fit on the flash chips.

That's a good point, thanks for clarifying.

Sorry to pollute this thread with this unrelated post. After this one, there won't be another post from me here.

Yeah, the "let's make everyone waiting for more than three years to get the thing done and my mortgage being paid" is an extreme nobody want, including me. On the other side, I don't want the "comfortable releasing" being "95% implemented" to be done for free, and the remaining 5% to finally be crowdfunded for 10 bucks.
If you don't like me doing crowdfunding, then that's your opinion. But please stop thinking that open source software is something people are doing for free on their spare time just for the pleasure (and bank account) of hardware resellers.


Oh, BTW, let's take a tour on ebay. There is currently an auction for Action Replay cartridge with Pseudo Saturn Kai v6.324 (latest version) pre-installed. Unit price is USD 60, 7 cartridges are in stock and 74 cartridges are already sold.
Now let's go on play-asia. Price for one Action Replay cart is around USD 30.
Now, quick math time ! 74 * (60 - 30) = USD 2220 gained so far. Not bad for pre-installing a free software that everyone can download from my homepage.


Back to the main subject : if I open a cowdfunding page to get some specific features to be implemented, that's for good reasons :
- I won't implement these features for free ... see above for the reasons why
- I'm confident these features can be implemented in a reasonable amount of time : if I'm not sure about a given project then I usually don't write about it on my homepage or in my blog

You don't need to detail about Save Data Manager and Gamer's Cartridge details : @privateye knows about them way more than you.

So, I stated that Save Data Manager won't be available in lite firmware, but that was a long ago. After that, I lost time to assemble more Gamer's Cartridge and "all-in-one" carts have their own hardware issues. As a result, there are currently very few solutions to get both Pseudo Saturn exploit, cheat codes and backup memory feature available on a single cartridge.
I still have few time for firmware development, so in exchange of Gamer's Cartridge not being available I would like to provide a similar feature for lite firmware. It won't be as convenient as in Gamer's Cartridge (because of lack of in-game support, and not being able to access SD card etc), but better than nothing.


also the main reason for this mod is to allow you to keep the action replay firmware in tact whilst still being able to have PSKL on it, as well as being able to use the cheats etc.

Of course, let's install Pseudo Saturn Kai on the cartridge. You can even install it twice, which is great ! But let's no forget to claim when its developer begs for a penny.


Last but not least, a forum is a place to share where to share information and everyone's opinion; if you want to unilaterally post something, then an homepage or a blog with comments disabled shall be more convenient.
I'm taking care of Pseudo Saturn Kai official thread, where a lot of people arrive to ask why a game doesn't boots (usually a lens or CD-R problem), or why it doesn't play correctly (because expansion RAM of their cartridge is defective), and I don't kick them because "your post is rude, get out of my thread, bwah bwah !".


End of discussion from me here. Sorry for the trouble caused and I wish you an happy cartridge modding.

i don't know who privateye is so i don't know the extent of his knowledge and i'm sorry if i came across rude i just didn't appreciate him posting links to someone else's stuff here, maybe i over reacted and if i did i apologise.

as to you having crowdfunding i have nothing against it and i'm glad you do, so if you thought i felt otherwise then i just want to to know i don't.
you deserve all the support people can give you.
