Some games won't work. For instance, Manhunt doesn't work on mine, it just hangs when the auto save kicks in when trying to start a new game. It then leaves a 109k file on the mm16 card which is smaller than what it should be. But this game also doesn't work with my 16meg Joytech expansion card. It only works with my Original Sony card.
