Super Mario 64 DS Cheats

Never lose all of your lives against the third Bowser
If you lose to the third Bowser, you will be thrown out of the warp-pipe that you came in. If you back down the blue stairs about where the heart is, you will notice four pillars. Go in front of the top left pillar and you will recieve a free life. If you do this every time you lose, you will never run out of lives while fighting him.
