Hello guys, i just bought a psp for about two month and i'm still a bit noobish at this kind of thing. at first i used 5.50 gen-d3 and i had changed it to prometheus 2 and i'm wondering if there's any update on this prometheus cause i've seen prometheus version 4,5 and so on. Do i need to update it? And if so how? could you direct me to any guide telling me how to update them?? PS : And is it possible to play MGS : Peace walker on prome-2??
