1. Open the UMD drive.
2. Insert a game UMD.
3. Turn on the psp
4. The game may auto-start, if not then go to "Games" and press the X button. Then select the UMD disk shaped icon and press the X again.
I am brilliant! But seriously, what firmware version do you have? That makes a big difference with how to go about running non UMD games.
