How to Make a CSO Game Work on Your PSP

The primary advantage of using a disk image file for your PlayStation Portable is that it preserves battery life. PSPs can accept two disk image formats: CSO and ISO. For CSO files to work on the PSP, you must place them in the correct folder, and the correct firmware driver must be selected.
