with my fingers
It is supposed to be able to play the PSP games, but the PSP can not play the Vita games
Yes, but only downloaded ones. The psp go doesn't have a driver for UMDs.
you have to download psp go games from the playstation store, you cant use the psp discs (UMD's) because there isn't a slot on the psp go.
if u mean can u play ps3 games on psp no the psp doesnt support that graphic settings
