How to Reduce the Size of PSP Images

Using game image backups (ISOs) with your Sony PlayStation Portable (PSP) tends to fill your memory stick up rather quickly. An average PSP game image takes up about 1GB of memory, and the largest PSP-compatible memory sticks available are 16GB. Factor in the fact that you may have PSN titles and homebrew on your memory stick, and 1GB per game leaves you with not much room. There is a program that compresses the ISO image into a CSO file, which is also playable on the PSP. The compression rate can be as much as 50% with some games. This means you can have twice as many games on the memory stick without losing any quality of gaming.
