How to Use ISO & CSO Files on PSP

The PSP is a handheld game console with many of the same features as the PlayStation 3. PSP games come in the form of a UMD disc, which is inserted into the back. As it is inconvenient to carry around a large amount of discs, you may wish to install downloaded games directly to the device. Downloaded PSP games are either ISO or CSO file types and can be acquired from various websites online.
