I have found only a couple similar posts and no resolution. I bought an ebay psp then took it 2.82>3.03>1.5>3.03oe-c with no hang-ups whatsoever. I never held a psp before I received this one. Thanks goes out to all those great guides out there! The problem is... When iso files are placed in the ISO folder (in the ms root), the unit reads no games no matter what I do. Tried w+w/o game in the drive, tried enabling/disabling No UMD, tried a 4gb and a 512mb card, even reflashed 3.03oe-c because I thought I might have somehow bungled the update! I have tried more than I can remember and I have tried way past my bedtime. I registered just to bring this problem to the front and I am open to all advice - even if it requires changing my FW.
