I've got cfw 4.01 m33-2. All my .cso files are in my ISO folder in the root of my PSP, i have a burnout.cso and final fantasy 7 crisis core.cso, both work perfectly fine but when i try to start fifa 09.cso it says the game couldn't be started. What can i do? Please help
Try downloading another version as it could be just the game that is corrupted, however i dont think it has anything to do with the firmware as fifa 09 worked on my psp with 3.90 m33-3 firmware.
