Hi, i'm new here. i have been searching this forum for the past hour for my problem but nobody seems to have the same firmware as me. I am running on 3.60 m33 firmware. I bought it like that. i have serveral CSO game files and have tried running it at the game tab. Everytime i run it, the sony psp screen comes out. After around 5 secs, it turns off again. i have tried changing the same file to an ISO with a decompressor but it still doesn't work. Can somebody please help me? Redirect me if there's such a post as well. Other people with the same problem have different firmwares from mine =/ thanks.
