This instructable will hopefully teach you how to create a .iso to play on your PSP. This tutorial only applies to people who are running custom firmware on your psp.
This is to only be done to backup a game you already OWN not one that you have DOWNLOADED.
For this tutorial I will be using a copy of 'Star Wars Battlefront 2' that I own. This also work on any other PSP game.
Step 1: What You Will Need
-A PSP running custom firmware
-A UMD of any PSP game
-Active ISO File Manager 2 (link will be provided [software is FREE])
