I programmed my own Onechip and put it into my PAL SCPH-102(1).
I attached the hex I read from empty chip, the onechip hex I used and the dump of the programmed chip.
Installation worked fine, imports and backups are played.
It ataached the diagram i used, too.
I inserted a original copy of Guitar Freaks and get the antimod-screen.
Does anyone have any idea what could be the cause?
