I do realise this there is no ps2 emu was just asking as I am new to the scene and have seen videos of people playing it on the PSP from a cso file loooolNo ps2 emu on the vita lol
San Andreas is not for the psp. What you saw was most likely them mirroring their pc screen to psp. You can do that with this homebrew, just need cfw and looks like it supports newer operating systems now.
I have a old laptop windows vista or 7 maybe with not so good gaming graphics would this method still work thanks in advance
