ok i havn't played my psp in like 2 weeks (wtf right) well i guess its because i lost my charger and finnaly found it. i charged it and i turn it on and the background goes red, then when it goes to the menu its silver. i check what version i have and its 1.50. I dont know whats wrong with it but i guess thats pretty cool. Could you originally change colors before or something? or does it do it monthly?
