Hi
When you first hover over PSPuae it automatically changes the screen to the first screen with A500, computer and the small window with A600 boot screen (disk moving in). Ok then a option box with a the triangle button flashes up. So hit the triangle button and a information screen comes in from the right with (start, internet search, delete, information) and at the Top, Group Content, select, then select By Format, it then shows the list of formats (psp, mims, playstation, pcengine, neogeo)
Cheers
Don
ps, Have ordered a pandora battery and magic memory kit.
