well this has nothing to do with any mario for nintendo just saying ok.this cheat is about a seceret area in the game inside peach castle go up to the door in the middle above has a green mushroom mark go above the door and jump in and there you have it a gold star and a few green mushroom all in your pocket and you can go there and collect all the green mushrooms again and again.This is my cheat for mario 63 injoy and continue playing.
