I recently got my playstation 2 modded with a Duo 2 chip, i also have backups of Gran Turismo 4 and winning eleven 8. Sometimes my winning elven works but i have to reset the playstation2 about a million times to get it to work. I have never gotten the gran turismo to work at all. I tried backups of Killzone and Grand Theft Auto Vice City and they worked fine. My plastation 2 is about 2 and a half years old. Is there something wrong with it? and by the way my original games work fine. Any suggestion as to what the problem is.
