I know nothing about my new gift, PSP slim, firmware is V3.71m33-2. It's a mod set. Obviously, I've no problem playing UMD. However, may the expert here teach me how do d/l ISO games to my memory stick so as to have more fun? In fact, I tried d/l the ISO game, but unsuccessful! I really need help, would appreciate if you could guide me step by step or point me to d right forum? Thank you very much.
