    You can not play ISO/CSO files on a PSP that has official firmware.

    You will need to use a Pandora Battery to downgrade.

    You will need a PSP that has 1.50 or custom firmware already installed on it in order to create a Pandora Battery. HERE is a guide for creating the Pandora Battery.

    If you have a SLIM PSP then you will need to download the below file to modify the Magic Memory Stick of the original you have created (This will work for FAT as well if you want to go stright to 3.71 M33-2 custom firmware). HERE is the file you will need. Just read the read me file which shows you how to use the application.
