yea, I have 3.90 M33-3 firmware and i'm trying to play ironman without the UMD and I created a ISO folder in the root of the memory stick and put the ISO/CSO in the folder and tried to play it. it starts out fine but has a (80020321) error. What do i need or is the ISO/CSO just corrupted?
P.S.: if it helps I used pandora to get 3.90 M33-3 and still have pandora battery. if that helps my case at all.
