: The first release might have accidentally excluded cutscenes, audio files, or specific levels.
: Errors that prevented the game from installing or loading correctly.
: The initial release's bypass or "crack" didn't work on certain operating systems or hardware.
: A PROPER release is issued when a previous release by a different group is "nuked" (invalidated) because of technical errors like out-of-sync audio, missing frames, incorrect aspect ratios, or installation issues.
