Oh, and if it is Just CSO's that aren't working, but your ISO's are playing, then you need to make a change while in recovery mode.

To enter recovery mode:
(1) First Shut down your PSP completely, then remove the battery.

(2) Put the battery back in, and turn the device back on, while holding down the "R" button. (You must hold down the "R" button before you flick the on switch)

You should now be at your recovery menu:

(3) Once there, Go to the menu option "Configuration" and press "X".

Now you should be at the configuration menu:

(4) Now Go to "UMD Mode" and cycle through the choices (which is done by pressing "x") until you come to the choice "Sony NP9960 -No UMD-".
After you have done that, go back to the main menu, and hit "exit".

Now your CSO files should work.
