Illegal distribution of ROMs is against the site rules.

like pear said, sharing ROMs is illegal and will probably result in a site ban. You can either do a quick google search or rip it from a disc of your own.

Also know that emulator runs are banned from the leaderboard, but you can still do runs and submit to the unofficial emulator leaderboard.

ok thanks
