I've installed DUO modchip on a V3 (GH-006) PAL PS2 motherboard, everything BUT PS2 backups and originals won't boot. PSX game boots fine and dvd also boots fine. My solderpoints are good. I've tried and tried again 4 times now, but each time the outcome is the same, it won't boot PS2 games, no matter if it's backup or original. It could detect that there's a PS2 games in the tray, but just at the moment it boots, the cd-rom just stopped, and on the screen it says: "please insert a playstation games...etc". Please help, anyone?
