Hey everyone, Today I'm going to mod two Playstations one is a SCPH-7502b and one is a SCPH-9002. The SCPH-7502b was one of the last revisions of Playstation to have the parallel port and is going to be my main PSX now. The chips I'm using in this video are 12C508A PIC Chips and they are being burnt with the MultiMode3 hex. Please see below for links to the hex, install diagrams, info about the mod and hi-res pictures of my install.
Enjoy :)
