It wont run with Rival schools and thats my favorite game. Would someone please tell me where I could download a fix to make mame faster. Extra says it wil make "game play" faster but RS is not compatible.

Not compatable with all MAME games as stated. Compatable with many, yes, perhaps even most. But occasionally you run into games, even popular games, that don't work. Such as Bust-A-Move and Pacman. Overal a very clean and easy product. Recommended for most.
