Roms are legal but you are supposed to already have the game you download.It is like a backup if the game breaks.One good place to get emulators and roms is www.nowhere.com.<this is a link to it.Good luck finding good roms.
EDIT: Sorry, you are violating U.S. Copyright laws.
U.S. Copyright laws allow you to make one backup copy of software you own. However, that backup copy is tied to your original. Even if you own the original game, you are not entitled to download a copy of it. Copyright law clearly states that the only copy of software you are entitled to is the one you make yourself. Furthermore, the is no such thing as a "24 hour rule", where you have to delete the rom within 24 hours. There is no such rule, as downloading a copy of copyrighted software not intended for distribution is always illegal, no matter how long you have it.
Closed.
