Hi I have had my PS2 chipped a few years back and it's been working perfectly till now. I assume it's stopped working for reasons unknown to me since when i put in a backup or import it gives me the red invalid disc screen. I have a V3 PS2 and i think a magic 3 modchip. Please if there's anything i could check or do to get it working. I'm a complete noob to modchips etc and there's no one i can take my PS2 to to get it fixed, since the guy that did my chip back then doesn't seem to be there any more.
