la compravendita di rom č illegale , ti allego alcune delle regole dell'emulazione estratte da mame.dk :
Remember, the purpose of an emulator is to preserve games (so that they don't disappear), to have all your games on your PC and to keep a backup of games you own in case the game (or arcade/home console) fails or has already failed.
It's for educational purposes only (in case you are an emulator programmer).
You will NEVER sell ROMS for profit. Most game companies don't mind the distribution of their game's ROMS because they no longer exist, but they WILL mind if someone sells them.
You will NOT distribute ROMS together with emulators as a package. And again, NO selling.
