i just bought psp1003 model, got someone to downgrade to 5.00 m33-6, i have put games on 4gb genuine sony card, they just won't play, however a mate of mine gave his backup games which are over 2 years old, they are playing fine, mp4 is also temperamental, some films work fine others don't. is there a way round this, maybe downgrade to different version.
problem fixed, apparently it was corrupt files.
