I just bought a PS2 and Grand Theft Auto 3 for it, first off the connector in the back for power wouldnt go in the slot so i sliced it with a knifw until it worked. Finally i got it to turn on but my game wouldnt play, it says Please insert a playstation or playstation 2 disc, well i tried my regular playstation games and they got the same message, but i put an audio cd in and it worked! whats goin on
