Ok, so I've been able to extract my VC saves using FE100 and get data.bin files. Renaming these files make them work OK as emulator saves in case of SNES games, but does not seem to work with other systems. I've read that you have to byte flip and pad N64 saves, but I can't seem to find detailed instructions on how to do so, so if anyone can explain that, I'd be grateful. Also, for NES saves, I haven't found a single topic on how to make them work on emulators. Anyone can help with that?
