well i have a psp 2000, and i had CFW on it so i could have game son it and all that jazz. and i got rid of it because i was tired of it, and now all of a sudden i cant play games from a UMD on the PSP, and i know it has to do with the CFW that was on it. i know cuz i researched it, but my question is, how can i remedy this problem? is there a way to reset the PSP or do i need it to be taken in?
