I am packing and ripping my old games. Hundreds of discs.
PCE CD games - cd is flawless. These discs date to 1992?
Sega CD- same discs is flawless
Psone. Oh. My. God.
Any fingerprints / skin oil left on the discs? Even if "clean" looking
when stored? Even trace oil? HEAVILY oxidize the disc surface.
Does NOT buff out or come off, it is a change in the disc surface.
This is a big big problem.
The bottom of psone games, for some reason are vulnerable to corrosion!
