Things You'll Need
Instructions
Install a PSP emulator on your PC. The vast majority of emulators are free and can be readily found on the Internet. Each one is different, though, so read the instructions to learn how to operate your emulator.
Plug your PSP into your PC using the USB to mini-USB cable.
Download the supported PSP game files from the Internet. Each emulator supports only a finite number of PSP games. To play the games, you must download the necessary files in UMD or ISO format. Check with the developer of your emulator to find out which games are supported.
Load the UMD or ISO files in your emulator while your PSP is connected to the computer to play the games.
