With 6.20 pro b-4 you dont actually have an iso loader or its build in whatever it is, but all games run off of the xmb screen. if i load my games into an iso folder on the memory m2, they dont run when i select them from the memory stick option. do i need to also put in an iso loader? i want to be able to run them off the xmb still just store them on the memory stick, i read other posts that people do it but no one sayd how they do it or whats needed
