Play with luigi: When you return to the game selection screen, press and hold L and R when you choose it by pressing the A button. Unlimited use of mushrooms: If you want to make unlimited use of the Mushroom Houses you just have to meet the following requirement: complete the Star World. Unlimited lives: Go to level 1 of the Mushroom World, the place where the first star coin is. Wait at the top of the stairs until the noko noko (the turtle) appears. Go down to the second or third step and let the noko noko go for you. Jump lightly on it, this should make it bounce against the wall and get 3 crowns. If you do this as a golden Mario, the Noko Noko will disappear after 25 strokes. After collecting a million coins: A second main game screen is unlocked. In it you will see a Golden Mario surrounded by a ton of coins. It is no use but it is curious.
