I was playing a game (SCT3) and then I used my card reader with my memory stick to modify some savedata. I put the card back in my PSP and all of a sudden SCT3 shows but with no background or icon pic. I deleted it, put the iso back on the psp and then it didn't show up. Now none of the iso games work and all the savedata has vanished. The iso's show up on the comp and the psp with background music and pic (apart from SCT3)but the savedata doesn't! I'm using 3.71 m33-2.
