Hi, i've installed a duo 2 modchip in my v5 ps2, I also had to put a new khs400r laser in it because it wouldn't read any disks. But the problem is that it only loads ps2 original games and dvd films. It does not load any ps2 backups and any ps1 games. Have tried the different boot methods but still no look. So what do you guys think, could this be the laser or the modchip problem. Cheers.
