Enter a level with Yoshi, Cape Mario, and a Fire Flower in reserve. Position yourself under a berry in a way that you can get the fire flower and get the berry at the same time. If you happen to eat the flower and the berry at the same time, the game will freeze. Several things have been reported while using this glitch. Sometimes when the game freezes, your coin count will rise until you quickly have 99 lives. Press Start and Select to exit the leve. One person's game froze, horizontal lines appeared on the screen, and weird music kept looping over and over again. Then came a buzzing noise, and he was returned to the file select screen, with his file deleted. Thankfully, that's not normal. Even so, this is an interesting glitch to exploit every once in a while.
