I am using the MPH firmware launcher, and whenever I launch 2.0, the web browser works fine, and so does the mp4 player. But I can't launch a UMD game, even if it is a game that works for 1.5! Also the "2.0" PSP says that I have no pictures or mp3's when I really do.
I tried re-installing the eboot onto my memory stick, but I have the same problem. Please Help.
