i know the swaping umd trick works with ATV Offroad Fury Blazen Trails ac-hoc mode. the online almost always looses connection but its still fun with the halo 2 like fetures such as chat room, buddy game search, and making friends online.
and if u get the game put me on your friends list: Evil007

other then that, i do not know of any other games that work. ATV works because it loads the whole level into the ram and u can take the disk out in single player and still play the level.
