I recently modded my PSP and put a few games on it, I am using a microSD with an adapter which I am assuming may be the problem, but I'd like to go through everything first. I have a PSP 2001 running 6.60 pro c2. I added about 8 games that all work perfectly, then I added a lot more new games, booted everything up, and they all show as corrupted data. The original games I put on still show up and play though! I can not understand why some work and some don't! I tried some sort of "fix" I found for pro c2 but it didnt help. I tried getting rid of a lot of games and trying just individual corrupted data games to see if it was a memory issue but they still show up as corrupted where the first few games still show up as working. I don't know what to do!
