Hey everyone, So I just got a 3DO FZ-10 from Ebay and it works great however, the discs are getting scratched as the games are spinning. You can hear it and the discs show a light circular mark left by one of the pegs just inside the cd tray. Any ideas how to fix this like raising the spindle maybe? I know first thought would be just file the peg(s) down, but I'm looking for other ideas that doesn't harm the system. Thanks.
