Hey Guy's

I have my PSP and I have CSO file extension game but my PSP can read only the PBP file extension game. Is there anybody who can help me regarding this matter?

Thanks in advance

CSO files are PSP game disk images, therefore they are not legal copies of PSP games and our rules do not allow us to help to make pirated games work.

Some demos come in .cso or .iso so it's not necessarely piracy.
