Hello this kinda seem like a weird question but i used to have a modchipped Slim PS2. I burned many DVDs without ESR and my Slim broke. Today i bought a new Fat PS2 but it seems it isn't modchipped, and i have many burned PS2 games. Do i really need to do all of those esr things from the start or can i just esr patch a dvd that has already burnt. I don't know anything about esr and stuff so i hope someone can help me.
