Thanks, it all makes sense now!! It will start with T because it is MMC3, S is MMC1. SRAM is additionnal RAM on the cartridge, usually battery-backed to handle save games in RPGs, but there also is games that have SRAM and no battery backup, so this just expands usual RAM, for example Kid Icarus, Me...

ok, so i understand the first part about the letters and the mappers, but the variants are confusing me. i dont know what SRAM is. So say that Batman returns is 128k PRG, 256 CHR and the mapper is MMC3 (4), what board is this? I assume it would start with S so it would be a SNROM, SLROM or SVROM. Th...

Thanks for the info!! That clears up alot Most companies that sell electronic components still sell EPROMs. I recently paid 3.11 USD per chip for some erasable 27C256s from Digi-Key. They were a little more expensive than the ones you linked, but they were also twice as fast, new, and came from a re...

ahhh, i see. i wasnt planning on doing that anyway, so it wont be a problem. ok now eproms, say i want to use Super Mario Bros. 3 for the donor cart, which has 256k PRG / 128k CHR, which type of eproms should i use? if i could have a list of all types (128k PRG, etc) that would be great.

so why cant you solder the eprom to the board? what is the best way to get the eprom in there without having to cut the cart? Notice that he didn't solder the EPROMs directly to the board (which would be a bad idea anyway) -- he soldered two DIP carriers that he can snap the EPROMs into. However, th...

wow that is an awesome list. but what does okCHR mean? You have to use a cart that has the same (or extremely similar) board. The Bigass NES Mapper list can help some: http://tuxnes.sourceforge.net/nesmapper.txt So if you're trying to make a FF2 cart (UNROM), you can use Skate Or Die, Pro Wrestling,...
