guys, i got a huge problem. i had a psp of ver. 3.51 and then downloaded the upgrade version of 3.72. i heard it could play games of iso/cso type. after downloading the new software, i also formated the mem stick and reset all settings. but the iso folder just doesnt appear on my pc after i connected it via usb. i also tried creating one in the games, mp_root and all the other folders but the game does not appear on my psp. sometimes it comes as corrupted data. PLEASE HELP!
