I need some help on this one. My son has a version 4, serial # U5 PS2 and would love to get him a modchip but not sure of which one and were to get it professionally installed with less than 30 days before Christmas. Only the best will do. Also would love to be able to back up/copy some games. I have a Dell PC with a DVD+R burner. What do I need to get the ball rolling?
