Hi today i picked up a cheap PSPGo and i was looking to add custom firmware, i connect it via USB to my pc and it recognizes it but it does not show up in Computer on Windows 7 (My Computer for older windows).

I dont own a memory card but as it has 16gb internal memory i wanted to utilize THAT instead of getting an expensive memory card.

I read in "downgrading" threads to put certain files into ms0: (older PSP model) or ef0: on the PSPGo...but how do i access this ef0:? i take it ef0 is the internal memory of the PSPGo yes? but i just cannot for the life of me find a way to open it so i can drag or copy files onto it =/

Any help would be great, cheers Stephen!
