working game emulator that doesnt run on classic

[cambo2121]

has anyone found a way to get a game emulator to run on the pre withought using classic. I found this http://moppixmovies.com/wordpress/?page_id=414 but im no good with code, and have no idea how i would go about doing it. i know that people have gotten things like doom working but an emulator that you can just drop roms into would be much simplier than that i think. hope someone can help.
