For those of you that are interested, here are the Sega Saturn games that support my 1MB/4MB RAM carts. Most of these games require the RAM carts in order to play them.
The ones that have (OPTIONAL) do not require the cart, but will have better performance with the cart

    Awesome! Too bad I already have 5+ various carts for Saturn… It’s a great deal. I paid 2×25$ + about 12$ shipping for two such carts from Jandaman, and it was a good deal!

  2. Is this cart a MOD cart? will it play Japanese imports?

    Is this similar to the 5in1/4in1 carts?

    Do you sell the above 5in1/4in1 carts?

    His RAM carts are not any kind of multifunction cart, aside from the fact that you can switch the cart ID between 1MB and 4MB, which is just a compatibility hack (I’ve never run into a game that actually needs this, but it couldn’t hurt to have it available). It’s a pretty decent price for a 4MB RAM cart in any case, especially when you consider shipping compared to some of the other places that would carry them.

  4. racketboy says:

    the games that need this are on this page — many of which are very good. Good luck playing them without a RAM cart.

    Does this fuction as a memery card as well? If so, how much can it store.

  6. racketboy says:

    No, it’s just for video RAM

  7. Zed says:

    A RAM cart isn’t optional to run Waku Waku 7, it’s mandatory. The game won’t run without at least an 1mb cart. Try it and see.

    pocket fighter is OPTIONAL for the 4meg ram cart. I play it fine on mine with jut pro action replay

    Hi, I have a question. I have Pocket Fighter and a 4MB ram cart, how do I know that I’m taking advantage of it? I mean, when I turn on the console and when the game is booting it appears a black screen with two options in japanesse letters, the first option has the word RAM so I assumed that woukld be the correct one, but I have chosen the second one many times and I see no difference withing the game, is there a way to identified the correct use of the 4MB cart? thanks in advance

    Marvel Super Heroes is OPTIONAL, the cart just decreases loading times and adds smoother animation, i am playing it right now without a ram cart.

    i have two Problems

    First Problem
    I own a Action Replay 4 in 1 plus Cartridge.
    This work fine with my unmodded PAL-Saturn, but the voice of Vampire Savior cames out with a reverb (every thing wich is talked comes 2 times out of the loadspeakers)
    The other Sound effects works fine.
    All other games wich i had tried, runs very well
    (Marvel Superheroes, X-Men, SF-Zero 1+2 and many others…)

    Second Problem
    can anybody scan a image(as jpg) of the backcover from Fatal Fury Real Bout(not Special)?
    I own the original game but these Cover is missing

    please send to

    Thanx and Greetings from Germany

    I also have a question:

    i have the official 4mb cart that came with vampire savior. will it play games that need 1mb to play also? or do i need the 1mb cart separately?

    also, would it be wise to buy the action replay 5 in 1 (aka 4m plus) to replace my st-key and my 4mb cart?


  13. salinas says:

    I got one of the 4mbram carts, It worked fine for a few hours, then my graphics got all jumbled up, now with or without the ram cart the saturn splash screen, dashboard, and games are all jumbled graphics. Did my machine get fried? or is there some way to reset, I tried taking out the battery for a while, but this didn’t help. any ideas?

  14. racketboy says:

    I would first make sure that the cartridge slot on your machine is clean (get rid of dust, etc)

  15. plincko40 says:

    I have an ST-Key to convert imports, and the 4MB RAM cart that came with X-Men vs. Street Fighter. So to play this game, I quickly swap the ST-Key with the RAM cart after the game is converted (before the intro screen).
    I recently bought Metal Slug, and I use this same method. The game works, but is a little slow at times. Is there any way to get the game to play at faster speed (like as fast as Metal Slug 3 on XBOX)? Or is this slowing a normal, unavoidable feature?

  16. racketboy says:

    That’s just the ways it is as far as I know…

  17. andrew says:

    i have the import version of marvel super heroes for the sega saturn and noticed it is a lot slower than the U.S version for the playstation. I tried using the 4meg ram cart and checked the options to see it was turned on but the game still plays the same. Hardly any difference at all. Should I have gotten the U.S version for the sega saturn instead of the japanese version? I read great reviews about how the saturn version is superior to the playstation’s but is this true only on the U.S Marvel Super heroes?

  18. racketboy says:

    I wouldn’t assume there is any difference between regions, but maybe you are correct.

    Maybe you should ask in the forums — somebody there might have a better idea.

  19. anon says:

    I got the action replay 4/1 plus and on xmen vs street fighter the intro screen shows, but when it says hit ‘start’ it kicks me out into the saturn bios screen and says “cartridge unsupported” or something like that. wth?

  20. D_H says:

    When you need a 4MB cart on most jap games (X-men vs SF for example) it comes up with jap writing and 4MB, then when its plugged in a screen with jap writing and 16 on it comes on. what does this mean, just curious as game works 😀

  21. anon says:

    Im wondering if the AR 4/1 Plus cart is defective (i just bought it).
    It works when i go in the menu and select “boot game w/out cheats” and i put an USA game. But if I put XmenvsStreetfighter it runs only upto the intro and keeps running if i let the game run, but if i hit start to beging playing, it kicks me out to the saturn bios screen and says something like ” cartridge not supported”

  22. racketboy says:

    I don’t recall the “16” message, so I can’t really help you too much there….

  23. Mike says:

    I want to reply to the guy with the Marvel Super Heroes slowdown with the 4MB cart. It’s a known problem that the 4MB cart actually slows down the game – something with the added frames of animation or something. Better to play Marvel Super Heroes without the RAM cart. Just thought you all should know.

  24. Ano says:

    Hello, I recently bought a RAM cartridge from here but so far I’ve tried different games (Vampire Savior, Dungeon and Dragons Shadow over Mystara) the game just says “Expension memory cartridge 4mb not inserted etc…” basically a message in japanese that says no expension cart found please turn off the system and insert RAM properly.

    So I don’t know what is wrong, could it be the RAM catridge I received is defective? Is there a settings in the Saturn’s bios to test whether a ram cartridge is found or not?

  25. racketboy says:

    Have you flipped the switch on the cartridge? That toggles between 1MB and 4MB mode.
    Let me know if that works 🙂

  26. Ano says:

    Yes, I tried turning on the console and booting the game with both the switch left and right. Left is for 1MB, right?

  27. Ano says:

    Ok, it works now! Don’t know why it didn’t before but I’m not complaining.

  28. racketboy says:

    OK that’s weird — glad you got it working 🙂

  29. Brian Riddick says:

    Okay…I looked at your cart, and was tempted to buy it…but it says to save shipping costs combine it with a mod chip…whats the mod chip…answer me this straight up…is your cart a 1 and 4 MB cart that will play Japanese imports such as most of the games above that are not American, or is it simply just a 4 and 1?

  30. racketboy says:

    Hi Brian — As mentioned in the comments above “His RAM carts are not any kind of multifunction cart, aside from the fact that you can switch the cart ID between 1MB and 4MB”

    It’s just for RAM, nothing else like booting imports.
    A Mod Chip is for booting burned discs, but I am currently out of them.

    Hope that helps 🙂

  31. Nick says:

    Hi Racketboy. Does your RAM cart work ok with King of Fighters ’96 without any gfx glitches?

    The Action Replay 4-in-1 doesn’t work properly with the game and some of the characters turn into black blocks or dissapear etc when they perform certain actions.

  32. Nick says:

    Never mind the above question. Turns out my 4-in-1 was faulty 🙁

  33. Arick says:

    Can this cartridge make a US sega saturn sega system play
    X-men Vs Street Fighter and other Import games that need a RAM cart.
    Does this work with regular imports as well.

  34. racketboy says:

    It won’t get your around the Region Code (booting imports) — just the RAM part.

  35. Arick says:

    Can this cartridge make a US sega saturn sega system play
    X-men Vs Street Fighter and other Import games that need a RAM cart.
    Does this work with regular imports as well.
    Please E-Mail me back

  36. Arick says:

    So this is not made to play imports then?

  37. racketboy says:

    Not the one I sold — you would probably want an Action Replay 4-in-1 Plus

  38. jollie says:

    heres some helpful info for anyone using a 4M1M Action Replay Plus, and trying to play King Of Fighters ’95: you are going to need to swap the Action Replay with the ROM cartridge during the screen that says licensed by sega. wait three seconds and then switch them quickly. because it is ROM not RAM it will not work without it.

  39. Harley says:

    Rats, out of stock. If this is something you make/manufacture, any ideas when/if more will be in stock? BTW, great job with the modchip. Didn’t work with a model 2 64 pin Saturn (I know I know, not guaranteed to work, but I tried anyways since it’s what I had first before buying a 32 pin model 2) , but was a breeze to install on a model 2 32 pin Saturn. My backups boot flawlessly. I’ve even played some with changing the music to my own choices.

  40. joe says:

    hey, im getting ready to purchase a saturn, and from looking at the list, im glad sonic jam was not on there. it’s one of the various reasons im getting the saturn, but would anyone know if sonic jam needs a RAM cart of any type?

  41. Carlo Olivar says:

    Re: Marvel Super Heroes – it uses the 1MB ram cart (optionally), and NOT the 4MB ram cart. This is the reason why the 4MB ram cart causes it to slow down.

    With the 1 MB ram cart in place, go to options screen of the game and turn on the 3mb ram mode.

    Additional frames of animation for all the characters will be added, making the game look smoother. Loading times are somewhat decreased as well. Its still not arcade perfect, but it is noticeably better that both the PS1 version and default Saturn configuration without the 1mb ram cart.

  42. Mark says:

    I did have both ST-Key converter and Capcom’s 4MB RAM cart that came with X-Men vs. Street Fighter, and I did use that method to swap the ST-Key cart with the RAM cart to load this game and other Capcom imports (Marvel Super Heroes vs. Street Fighter, and Vampire Savior). I believe along the years (5+) this method destroyed the cartridge slot. So I believe the 4-in-1 or 5-in-1 (whatever it is called) is the best chance to play Japanese imports that requires either the 1MB or 4MB expansion.

  43. Eduardo says:

    I’ve bought one of these 1MB/4MB RAM carts from you 10 years ago, and it never got to work. Do you know why it happend?

  44. Racketboy says:

    Hi Eduardo
    It’s honestly a bit hard to say — especially 10 years later…. I don’t sell that same model anymore.
    It could be the cartridge, but it is actually somewhat common for that slot of the Saturn to go bad. The only way to know for sure is to try another cartridge.

  45. Eduardo says:

    I have an official Sega 4MB cartridge and it works great.
