An alcove was added into the castle exterior, directly above the door. There are three Brick Blocks on the right side, which Mario, Luigi, or Wario can break to enter Battle Fort. The remake has a few additional features within the courtyard.
Any character except Yoshi can defeat the Boos. The Big Boo and three additional regular Boos appear when the player has at least 15 Power Stars, with the Big Boo replacing the regular Boo in the hallway. Once the Power Star is obtained, Yellow Coins replace the Red Coins. In Super Mario 64 DS, at least 3 Power Stars are needed for a Boo to appear in the hallway and eight Boos to appear in the courtyard, each containing a Red Coin obtaining them causes a hidden Power Star to appear behind the fountain.
