Hi. I got my hands on what was said to be a prototype. The disc won't play on console and won't open on PC, so I don't know what it is. The seller couldn't clearly remember/state where the disc originate from, and had a fair amount of other assorted identified and unidentified discs. The disc says: "ETG V0.0.1 The very first working disc" My first guess is Gex: Enter The Gecko. There are two distinct spots on the disc that I think are causing trouble reading it. So I wonder what's the most solid program or method for making perfect backups of almost broken discs? I also wonder what's the best of the best methods of backing up PS2 prototypes? Thanks a lot in advance.
