NEW PSone

I've been told that if I get my new psone chipped, that some games have masks on and the program needed to remove this is very expensive. (I think it's tosh).
Can anyone help, What is this program called, where can I get it or will the psone work when it's chipped.

Cheers All

there two ways to chip a psone one way you need a boot disc to play imports and the other way plays any game go to www.kanection.co.uk for the wiring diagram
