In the SNES game, the player can only save after completing certain stages or finishing any Ghost House or Fortress. In the Game Boy Advance game, the player can save inside of a course or on the world map; the Game Boy Advance game also saves the player's power-ups and life count, whereas the SNES version starts the player out as Small Mario with 5 lives each time a saved file is loaded.
