-Normally happens right before a loading screen. This error is thrown when a file requested for loading isn't found in the CD table of contents (should never happen on an original CD, except if the TOC zone is physically damaged).
-If the CD is an original one, it's certainly dirty or scratched.
-If the CD is a copy, it's certainly re-authored (not an exact copy of an original). Even if the files are the same, the CD image structure can be altered and detected.
-This is the case for games using file versions in their ISO 9660 structure, like [[Metal Slug 2]]. Most Windows ISO image editors strip the versioning info which is needed by the game to identify the files. Use [[mkisofs]] or edit the loading tables in the main PRG file.
