Hi guys, I have one of the first version PS2 with a magic 3.1. My PS2 for some reason now can not play my backed up PS2 games. It can't play DVD or cd backed up PS2 games. But it can however it can still play my orginal copy games and backed up psone games. My question is what do you guys think is wrong with my PS2? I thought it was the laser at first but it is still capable of playing backed up psone games. Could it be the modchip? I checked the wires and nothing looks wrong. Thanks in advance to whoever can help me out.
