What's going on??

[spooky]

Basicaly the guy who chipped it has done a lousy job!

I would need to know which version of PSX (SCPH ????) your friend has before i could be of more help.

My first thoughts would be that the wrong code has been used or the wrong installation diagram.

I have seen some really naff installation jobs before, melted and lifting tracks, blown fuses, short circuits and not to mention installed chips that have'nt even been programmed, but if you can supply some more information then i may be able to help further.
