Hi guys
I want to make a PAL repro of Metroid Zero Mission for SNES and looking around my head is spinning
Would a FIFA 96 cart make a good donar cart and what is the easiest method of wiring in an EPROM? Would I be better off buying an adapter PCB and TSOP? I have an EPROM writer so no problem there, or if TSOP I can get it programmed when I buy it.
Any help would be appreciated, I'm doing this as a gift for a friend for xmas.
Whether or not it will work on that board, you will need to patch the ROM with uCON64 or the game's anti-piracy checks will fail and you'll get a piracy screen when you turn the game on.
As long as the donor cart he uses has a 64Kbit SRAM then the piracy check won't activate, even without patching. AFAIK its only triggered when a sram size other than 64Kbit is found.
And even if your donor has a bigger SRAM, like a 62256, you can ground the SRAM's A13 and A14 and the check should pass.

Not true. I used a SHVC-1A3M-30 board for mine, and had to patch it. I have a feeling there may be mirroring.

That could very well be.... but i've made both a Zero Mission and a Redesign hack using NBA live 96 (single chip versions) as donors and they worked fine without patching, so that's where my conclusion came from.
That's weird. According to snescentral, the 1-ROM version of NBA Live '96 is SHVC-1A3M-30, same as mine. Not sure what's up with that...
Made a few Metroid rom hacks for the super nintendo and as long as the ram size was correct anti piracy would not kick in. I had a few instances where it did, but after cleaning the pins on the game it would work which is weird.
Well, in any case, patching out the check doesn't hurt anything, so it's probably worth it regardless...
