    Brilliant =D I like the idea of byte swapping the ROM there to make it easier to fit a 27C801!

      Thanks. Most of tutorials doesn't really explain why doing it. I though explaining it would be intresting, especially when you only need to do it in this type of repro.

      Yes, I've already answer to that to "Sarben Minariil" in the bottom comments. I tried a 1A1M game (Stanley Cup) on a 1A5M game (Sim City) and it saves.

    Hello. good video, for beginners like me. Can you say, If i have a PCB with 256k sram, can i use it for games with less sram?

    • @TheRealPhoenix_Retromods
      @TheRealPhoenix_Retromods  8 ปีที่แล้ว +1

      Mmm I've never tried, but theoretically, it should. I now the wiring of the between 64k and 256k are slightly different (RAM chip have direct link to the MaskROM's I/O), and it sould be ok since we don't need to access to the memory block from 64k to 256k. I could test that quickly this week end.

    Hey, thanks for the video. I want to replace the eprom of my japanese games with english translated version. Would I follow the same steps but instead of using a donor cart can I just use the original cart? Do I just desolder the old eprom, apply the english translated rom using the gq-4x then resolder as you did here?

    • @TheRealPhoenix_Retromods
      @TheRealPhoenix_Retromods  7 ปีที่แล้ว +1

      Hi, Yes you can reuse the original cart as donor of course, but you cannot reprogram the original maskrom. Those chips are one-time programmable so you'd still need to burn the game on a 27C801 and manually swap OE and pin 31.

  • @StickPeopleAndPuff
    @StickPeopleAndPuff 3 ปีที่แล้ว

    So if I wanted to make the game "Sailor Moon - Another story" as it was never released in America, I would need to use this chip (m27c801)? According to the SNES database The game is HiRom, has a 64Kb SRAM, and has a size of 24Mb. I would just need to find the appropriate donor cart? the 24Mb is the actual size of the ROM correct? and the m27c801 is 8MB so it should be sufficient?

    • @TheRealPhoenix_Retromods
      @TheRealPhoenix_Retromods  3 ปีที่แล้ว

      No, it won't be enought. The game is 24Mbits (24Mb) so 3 MBytes (3MB). A 27C801 is a 8Mb (1MB) so it would need at least 3x 27C801 eproms to work. Your only options for make a repro of this game would be:
      - A) using a 29F032b on a DIP adapter on a SHVC-1J3M (HiROM/Saves/64Kbits of RAM)
      - B) find a SHVC-3J3M (which is very rare, used only on early version of FFIV in japan, then replaced with the BJ3M ) and split the rom in 3x 27C801
      - or C) find a custom DIY PCB supporting 27C322 (like retrostage.net/index.php/product/snes-megarom-2-0/ ) since this eprom is 32Mbits (4MB), assuming your burner can program this chip.

    How can I use the EPROM 27c4001 to make games using 1Mb ?
    I have only this eprom and I wanna to repro Zelda, is the possible?

    • @TheRealPhoenix_Retromods
      @TheRealPhoenix_Retromods  8 ปีที่แล้ว

      The 27C4001 is a 4Mbits (512ko) while Zelda is a 8Mbits game (1Mo), so you'll need 2 of them. Also, VPP pin should be linked to VCC pin, NOT on the board.
      I'v never tested a repro with this EEPROM. You'll also need to find a LoROM donnor car with 2 Maskrom + saving features + at least 64Kbits of Sram (2A3B).
      I don't think the byteswap will work (it's designed for 27C801), so just splitting the ROM file and wire manually the two EEPROMs. Not sure this will work though, it's possible that you need to rewire some additional pins to the LS139/MAD mapper (you don't have an A19 line on a 27C4001).
      If you don't have a compatible donnor cart, it's possible to make your own memory mapper by adding an LS139 between the 2 EEPROM or rewiring pins on the LS139 on the cart.

    • @TheRealPhoenix_Retromods
      @TheRealPhoenix_Retromods  7 ปีที่แล้ว

      There's no really just one place where everything is explained. On some retrogaming forum people explains some stuff, and you'll have regroup differents sources. The thing is doing a repro is seens as a bad thing by the retro community especially if you're using a donor cart, since you're sacrificing an original hardware. I have to make a video about non-donor repro which are way easier nowdays.

    • @TheRealPhoenix_Retromods
      @TheRealPhoenix_Retromods  7 ปีที่แล้ว

      If you alraedy used snes rom utility to binswap, removed the header and split the game into 2 files of 1Mo (8Mbits), then it's juste your two eprom who are inverted. Try to desolder them and invert their position.

      I've never tried something like this. 12mb is mostly using 2 Maskroms, and a 8mb will only use a single 27C801. I'd say it is technically possible, but you'll have to check if the MAD mapper (or the LS1349) handling the two eeproms need some routing.

    • @TheRealPhoenix_Retromods
      @TheRealPhoenix_Retromods  7 ปีที่แล้ว

      Well it depends of the repro but it is definitly doable. You'll have to unsolder the Eeprom (or the two Eeproms, IIRC Metroid is a 24Mbits LoROM game), then reprogram them. After that it'll depends of what's inside the repro. It could be a AM29F32B on an adapter if the PCB is a donor, or if the PCB is a new one it could use a 27C322 or (two 27C160), etc...

      I don't think I'm going to to the 4 x 27c801 solution. The 27C322 + two 74HC255 is way simpler. A few years ago the AM29F032B solution was the best, but now the chip is too expensive. I honeslty think using brand new PCB for 16/32Mbits games is a better, simpler and cleaner solution (and no donor).

    Hello!! This is a very interesting way of how to program your carts. Congrats!!! :) It seems that you have weld everytime you need a different game. Is there an easier way of how to reprogram the memory? I mean not welding. Anyway thanks for your clues :)

    • @TheRealPhoenix_Retromods
      @TheRealPhoenix_Retromods  8 ปีที่แล้ว +3

      Thanks! Yes this is more for a permanent way to have a custom game, then use it as a normal one.
      If it's just for testing you EEPROM, you can solder pin sockets (don"t forget to swap pin 23 and 31) so you can plug/unplug your EEPROM. But this will be too thick to close the cart shell.
      There are others solution like the reprogrammable reproductions on www.infiniteneslives.com/snessupplies.php, but you'll need their custom programmer.
      If you just want to play a game the Super UFO Pro 8 is the cheapest solution, where you can store game on a SD Card www.emuparadise.me/reviews/SuperUFO/.
      More expensive solutions with a better support of games and additional features also exist, like the Super Everdrive or the SD2SNES.

    Hello, your video is very good. Could you explain me better the PCB cart code: SHVC - XXXX - XX. What I really want to understand is the fourth X: Type of the memory (B, M and N). Are PCBs compatible with each other? Or will the burn of a game only work on a card of the same type of memory? Thanks!

    • @TheRealPhoenix_Retromods
      @TheRealPhoenix_Retromods  7 ปีที่แล้ว +1

      Hey.
      The 4th digit is the memory mapper. You only need to know if it's a B or M (which means there is a save system) or N which means no save system.
      There are some games like Legend of Zelda (I think) which exists in both XXXB and XXXM: 1A3M (1 maskrom, LOrom, 64Kbits of RAM and MAD mapper) and 1A3B (1 maskrom, LOrom, 64Bits of ram and LS139 mapper).
      If you a game which needs a save system on a XXXN PCB, it's possible it won't boot, or at best you won't be able to save. You can put a "non-saving" games on a XXXB or XXXM PCB it will work, but the saving will be useless.
      Just be sure whatever you're doing to respect LOrom or HIrom (XAXX or XJXX).

      The Real Phoenix Cool. But I'm a bit worried about FFV as the translation makes it 20megabits. I guess it's why I gotta get a TSOP III based chip right?

    • @TheRealPhoenix_Retromods
      @TheRealPhoenix_Retromods  7 ปีที่แล้ว

      Ouch, yes. Since FFV is a HiRom with a save system of 64Kb, a 16Mbits is doable on a 2J3M. But 20Mbits this is going to be tricky. If you still want to use a 2J3M donor, here's how I used to do them back in the days:
      - Remove the header,
      - Expand the ROM file to 24Mbits,
      - Split manualy the ROM into a 16Mbits (2Mo) file and a 8Mbits (1Mo),
      - Burn the 16Mbits into a 29F016B put on TSOPIII adapter (NO SWAP),
      - Burn the 8Mbits inot a 27C801 (NO SWAP),
      - Since Manually wire the 27C801 swapped pins.
      It's tidious, and honesly, I strongly recommand to use PCB like the ones from RetroStage.net for simple repros. (retrostage.net/index.php/product/snes-megarom-2-0/ unfortunaltely out of stock right now)

    first of all thank u for the awesome Video. Now I got a Question:
    I want to repro a game with 64kbits of Sram. the games I got flying around only got 0kbits sram and 16 Kbits.
    What are my Options here? Do I need to search for a game with fitting sram or can I mod it in any way?
    Thank You in Advance

    • @TheRealPhoenix_Retromods
      @TheRealPhoenix_Retromods  7 ปีที่แล้ว

      Well, it's always possible to hack a donor to fit your needs. With no ram on your donor you'll have to recreate the saving circuit (meaning at least a LS139 and a bunch of resistors, plus the battery). Then put everyting on a perfboard and a lot of wire to link everything.
      The 16Kbits ram will be way easier with just some traces to re-route. The only differences between Sram size on the PCBs are the additional addresses to be linked properly to the memory mapper and the maskrom. I don't have the scematic in mind, but I've already did it for Shiren the Wanderer (256Kbits sram on a 64kbits donor). If you have a 64kbits you can compare the traces and you'll see you'll something like like 4 traces to rewire.

      La première étape serait d'ouvrir pour voir les PCB que tu as
      Ensuite c'est de regarder sur SNESCentral snescentral.com/system.php quels jeux tu peux faire avec.
      Par contre je vais être franc, si tu chercher à faire des jeux type "32Mb + sauvegarde" (genre Secret of Mana 2) je te conseille d'acheter direct des PCBs tout fait (par exemple chez Retrostage, je sais pas les frais de ports vers la France, y a ptetes des équivalent en Europe)
      Ca sera beaucoup moins la prise de tête. Si tu as des donors, c'est toujours possible mais attends toi à ce que ca devienne chaud à un certain point (ne serait-ce que pour trouver des AM29F032B à bon prix).
