hello peeps, i just fitted in a MXL2 in a ps2 v6. this is the first time i'v done this. all the bios wires seems to be okey, because psx backups boot. i cant boot any ps2 backups cd-r and dvd-r. backups used to work in other ps2's. is it the modchip or did i install something wrong. do i need special wire for some of the connections?
