maybe someone can help me? After formatting memstick to fat32 on pc and then formatting on psp I end up with the same issues. certian games were added first to the ISO folder such as parappa and manhunt2 and patapon they did not show up in the xmb. I left those there and put the known working iso games from before (rockband and jackass) on there and they showed up and work!! I have been told its because of the fake mem stick but how can that be when it apparently works?? Im thinking maybe the ISO games are corrupted and are not showing up like the others. ANY SUGGESTIONS!! in the meantime I will try with an authentic sony stick.
