Is there a way to play all Xbox games on the 360. I don't mean burnt games I mean the real copies. I know they aren't all compatiable most of the games i want are but a few aren't I really want Riddick which isn't. The guy at Gamestop said it was possible to play them all with some kind of program off the internet. That sounds kinda reasonable to me since people know how to hack everything now a days. Is there such a thing?
