My autistic son was given a game for his old psp and we have totally lost touch and forgotten everything we knew about how to use it. He has a psp1003 which is able to have homebrew. When we put the given umd game (TRON EVOLUTION) into the player we got the message. The system software of your psp system is version 3.52. To start, you must update to version 6.31 or later. Could somebody point us in the right direction, we are guessing there is probably a guide somewhere but we really don't know where to start!! Thank you for your time.
