X-Men Mutant Academy Back-Up

[CJackway]

I got my UK ( SCPH - 102)psone chipped the other day and copied some games for it. I copied a back up of X-Men Mutant Academy which worked fine on my friends chipped playstation (not Psone) but doesnt work on mine. After inserting the disc it attempts to read it and fails it loads tho the screen where you can choose to play music or view memory cards. The psone one keeps trying to load the cd but fails.

Can anybody PPLLEEAASSEE HELP

Thanx CJackway
