[ching]

Will the games usually fit on a cdr if extracted to hard drive and burned on a cdr, and what is a ps2 patcher what does it do can anyone please tell me were i could get one. How big are ps2 games, do you need a dvd burner to burn and how do you burn them by using a normal cd burner. Your help is appreciated thanks.
