I always thought of Roms no diffrent then downloading mp3's, and I wouldn't have mentioned emulators if I didn't know for certain they were legal.

No one cares about old playstation and n64 games, no one looses money on that anymore, those games arn't made anymore, the people who created them have gotten all the money they will ever get from them.

Plus I heard that owning a game allows you legal ownership of that rom, specually if you dump it yourself.
