i was woundering if i can change a .fds (famicom disk system) rom (image) to a nes rom. so i can burn it with my epprom burner and play it on the nes and/or also be able to play it on my GBA (pocketNES). the game i like to do this with is super mario bros. 2 (J). or, i don`t think we are suppose to link roms here but if we can u guys/gals just link the image. or the main dir.
thanks,
ryan

You have to hack the game manually to use one of the mappers supported by an emulator. I believe there is such a mapper hack floating around (try searching eMule).

Msg me if you want a MMC3 hack of SMB2J. Most other pirate versions of the game you'll find on the 'net use obscure mappers that probably won't be of much use to you.
