they both work great. i checked every game they all work. i only have one set of the thing to hook it in tv and to plug it in the wall. the wireless mini controller works on both but the black one only works on the ps2. there are 11 games for the ps1 and 6 for the ps2. and the ps2 comes with a 8mb memory card. i only want to sell $110 OBO. no trades or emails. just call or text for more information
