Gauntlet (Japanese, rev 12) is a localized version of Gauntlet for the Japanese market. This revision likely includes a full translation of the game's text and menus into Japanese.  The 'rev 12' designation implies that it's a later revision and therefore might contain various bug fixes and potential gameplay adjustments.  The game retains the same core dungeon-crawling gameplay as the original arcade release.  The localization showcases the global appeal of Gauntlet and Atari Games' effort in bringing the game to a broader international audience.
