Installing PSP ISO games onto your PSP
1. Connect your PSP to your Computer.
2. Enable USB connection on your PSP.
3. Copy the CSO/ISO file into the ISO folder on your memory stick.
If you don't have an ISO folder you will need to make one
The ISO folder needs to be created on your 'Memory stick' next to the PSP and MP_RT folders.
4. Close the USB Connection and disconnect the USB Cable.
5. Insert a Game or Demo UMD into your PSP. (It must be a Game or Demo UMD, you cannot use a UMD Movie)
The UMD is needed in your PSP to pass the 'UMD Check' the PSP does when starting the ISO.
6. Scroll the 'Game' > 'Memory Stick' menu and you should see your ISO as one of the games on the menu.
7. Highlight your game and press 'Start'
