Not all patches actually work on real hardware. A lot of times, patches are built using ZSNES, not realizing that ZSNES utilizes a lot of hacks to get games to run such that hacks designed for ZSNES often won't run on an actual SNES. That's part of the reason byuu is so devoted to accuracy with BSNE...

Use the one with the good checksum. If it doesn't work, see if it has a header or not. If it does, try removing it, if not, add it (in NSRT, right-click on it and add or remove header, it doesn't matter what type of header you add). The checksum might be bad after patching, some ROM hacks don't both...

I have a feeling that the epoxy blob on your board is the decoder (in combination with the 139), so that board of yours is next to useless for design REing. My board will be significantly smaller than the official ones anyway due to smaller chips, the lack of a battery, and better PCB tolerances. Ye...

It shouldn't have mattered that you applied the patch to an .smc file, chances are that between the .smc and the .sfc, one had a header and one did not. Applying a patch intended for a headered ROM to an unheadered ROM or vice versa will corrupt it (that's why I said to check the README for the patc...

The Sanyo ROM appears to be discontinued, and I already have a better alternative in mind for SRAM (although it's a 3.3v part, so level shifting's gonna be a pain...). I'm also looking into Micron FlashROMs which, although they are also 3.3v parts, they have a significantly large x8/x16 parallel Fla...

You need to check the readme on the patch file. Some patches are meant to be applied to headered ROMs (because some people are ignorant and continue to use headered ROMs >.<). Just be sure that the final ready-to-burn file has the header removed. Also, filename doesn't matter AT ALL when it comes to...

Depends. What game is it?

I've been working on a project to build an SNES cart board from scratch (no special chips, MAD-1 decoder), and the one thing that I've been putting off for last is the MAD-1 decoder. I found neviksti's post in this thread http://nesdev.com/bbs/viewtopic.php?t=4450&sid=0a852e0496df6c70188b08a7cfd8eec...

Yes, you can use a SFC cart as a repro donor for an English translation of the same game. Depending on your region, you might need to swap out the CIC for one from your region though. A lot of people here have very strong opinions on repros, especially if you're using a good game as a donor. Persona...
