I have a duo2 chip installed my ps2. When I boot with the chip disabled, it boots orginals perfectly. However, booting backups is a different story. I keep getting the red please inserts ps2 disc screen. Randomly the backup will boot but it usually takes 6-7 tries. At one point they were working first time but now it takes a bit. Any suggestions? i checked the wires but they look ok, any specific wires I should check to make sure?
