This is a revision of Secret of Mana for the Super Nintendo, the original game being developed and published by Square. The 'Rev A' designation likely refers to a later revision of the game cartridge, perhaps with minor bug fixes or improvements compared to the earlier version. The core gameplay remains the same as the original action RPG.
