I know the 80 gig is compatible with most all, but the 40 gig is not compatable at all. That said, the 20 gig and 60 gig are comaptible with many. There is a spot on Sony's website that you can put in titles and the system you have and it will tell you if the game is compatable or not. I know for a fact GT4 works on the 80 gig. If your wheel plugs in with a PS2 cable, you will have to buy an adaptor as all the PS3 controllers use a usb port plug. I think they are aboput $15.
