It shouldn’t be an issue, I mean, they work on real hardware. I have a fairly large collection of hacked cartridges. I seem to remember trying out a megaman rom that I hacked myself when I first started messing with retropie. The same rom works on an actual cartridge in a real nes.
..actually come to think of it, that particular rom was hacked twice. I hacked somebody else’s hack. lol
It could be. I’ve had to pad some roms, by duplicating them, then splicing the files together to get them to work on hardware. But I think that’s only because the chips I bought were large enough for the biggest nes roms.
The guys over at nintendoage may have some advice. That’s where I learned to hack cartridges.
ok, made a break thu!
i found another completely new SMW rom and alls good!
ok so this means even if all checksums etc are ok, the patch still may mot work, it just finding that correct rom! out of 6 SMW roms I’ve now tried to patch, only one rom has taken any patch add
