This is a revision (Rev A) of the US release of Mike Tyson's Punch-Out!! for the NES. While retaining the same core gameplay loop—the unique rhythm-based boxing mechanics—this revision likely features minor bug fixes or technical improvements over the original US release.  It still offers the same challenging boxing experience and memorable roster of opponents, making it another highly sought-after NES classic.  Nintendo published this version of the game.
