Another edit after the one above:Wipeout pure i believe has a safety mechanism to stop this, as when the race starts, if you dont have the umd it doesnt work(very unfortunatly.) And gretzkys doesnt work either(less unfortunatly ps if you have gretzlys turn down the game speed to zero, much smother animations, no more head aches!)
