n64 and ds dont need gecko you can replace the rom with cafiine just fine and you dont have to deal with rom bigger thanoriginal and whatnot, only nes,snes and gba need gecko becuase you need to inject the roms since there is no rom folder they are fused with the executable tahts why you cant use bigger roms or while injecting you will break the executable.@FIX94 Do you think similar injection apps like Snesinject could be made for injecting N64, GBA, etc ROMs?
