I'm a bit rusty on this subject, but, You need custom firmware, denoted by M33 on the end of your firmware version.
Your PSP needs to be a 1000 generation, phat, or 2000 generation. Most 2000's that is. Later ones got a new uncrackable motherboard. (things might have changed there too).
A .cso file is unzipped, and the psp will play them, and .iso's which are a compressed .cso, these play fine too.

gen B is the latest, and yes you can run .cso files Ocram.
