Well I suggest you return it to the Guy who sold it and fitted it for you and ask him for a refund and get it removed then get one of the Latest DMS3 Mod Chips Fitted as it is the chip of choice among PS2 Gamers and it will :-
1>. Allow you to direct-boot all PS2 games including backups, imports, originals, silvers and DVD9.
2>. Can direct-boot PSX games including backups, imports, originals, and silvers.
3>. Plays any region DVD movies without Macrovision or RGB (green-screen) fixed.
4>. Boot applications such as the PS2 Reality Media Player from memory card as soon as the system starts up
But in the end the choice is yours !!!
