How you delete a game on a psp go?

1. Turn on your system (with NO device or game in it)

2. Click X. There will be a list of icons that are your saved stuff. Eg., An Ogre head for a Shrek game.

3.Just click on one, press it, and select the option DELETE. Do this to however many you want.

(NOTE: This works on PS2, so I'm not sure if it'll work on PSP. But it's worth a shot. Good luck!!!!!!!!!!!!!!!
