How to Reduce the Size of PSP Games

When backing up your Sony PSP games, an ISO file is created on your computer. The ISO file is the entire retail game backup file. When placed into the "ISO" folder on your PSP memory stick, the ISO file becomes playable on the PSP without the game in the PSP disc drive. This helps make the PSP much more portable. The only downside to this is that your memory stick gets filled up very quickly as the ISO files can reach up to 1.8GB in size. There is a tool that can compress the ISO files while retaining their playability.
