If it's already been done i'm sorry ! I have cracked it, i made a image of the game using alcohol 120%, then used dvd decrypter to burn the image at x2 speed only. it plays on my sons ps2 with matrix infinity chip, but not on my daughters new slim style ps2 with similiar chip. i tried first of all using alcohol to create and burn image but it would not play. i am using datasafe dvd+r discs. Now for gran turismo 4 !
