There are a host of PSX mod chips. (I'm not involved personally but I have a friend who is). From the 1000 series up to the, I think, new 9000 series, 12C508's are the preferred PIC but I've seen installation instructions for F84's. There are standard, "stealth", and some other new one now. If you really want to know about them there are plenty of sites that offer the software.
