I have a PSP 1000 (phat) with 5.00 m33-6 CFW. I ripped some of my games to my memory stick to play without UMD's, but now when I go to save or load a save file (I found this happening in ALL of my games) 75% of the time the XMB-looking saves menu pops up and I can do what i need to do. But sometimes it will go to a black screen, not showing the saves menu. This is really annoying and I would really like some help. Thanks.
