How to Create ISO-CSO Games For PSP

The Sony PlayStation Portable (PSP) uses universal media discs to play its video games. These universal discs can be backed up to a computer and used in case the disc becomes damaged. The backed up game is saved as an ISO or CSO file. The CSO is simply a compressed version of an ISO file. Backing up the PSP games is very simple as you only need a universal serial bus cable to transfer it to the computer.
