I have a burned CD with some bad sectors that I'd like to recover (it's not a game, it's a rendered animation from 1999… and unfortunately, it's zipped to save 0.1% or so); this makes me want to go hunting for a couple hundred CD-ROM drives to save it…
ddrescue to image the CD. mount the image. copy off files (bad sectors will all be 0). unzip and see what you got. if its a small amount i'd bet you would have something usable if not eperfect.
slight edit: unzip with option to keep the broken file (with the hope, unsure if this is true) that unzip can be resilient in the face of errors and keep on unzipping. (I know from experience rar is).
