Hi I have a psp 2000 I its on OFW 5.03 I want to downgrade it to 5.00 m33-6 so I can use its use a certain plugin to play my psp games thought component cables on the big screen in full screen mode. My understanding is 5.00 m33-6 is the only one that supports the plugin. I remember hearing about a program that can check what kind of motherboard you have. Does anyone know what I am talking about?
