you have a rom burned onto a cartridge by someone who made off with a lot more of your money than he deserved
Maybe, I don't know. All I know is that it's a nes cartridge of Mother that plays well. Even if that is what happened, it's still pretty rare to find one of those and worth it to me because I'll take a cartridge over a rom any day. I hate roms. FFIII is the only one I have.
