hey guys! i wanna go through and update to 3.03 oe-b to get to play psx games, but i dont know where to start. Do i have to update to 3.02 oe-a first and then go update to 3.03 oe-b? I have a 1.50 psp non mobo. Links would be nice. And i think this is why they need a custom firmware guide thread arghhh! thanks guys!
