I love the Ace Combat series. You probably figured that out by my name. But if not...I do. So naturally I'll be wanting to play the new game for PSP. I'm on 5.50 Prometheus right now but with large games I tend to just buy the UMD's because my memory card is only 4GB and I like to keep as much on there as I can. Games like Valkyrie Profile, Crisis Core, etc. What I want to know is: A) Will ACX2 work on Prometheus as an ISO/CSO? If so, what sort of file size should I expect? B) If I buy the disk, will it work on Prometheus, or will it require an update? If so, is there an update on the way to CFW to bypass the issue? C) I have a spare battery kicking around. Is it true I can make a Pandora Battery using just my existing flashed PSP? How is it done?
