In World 4-Castle of New Super Mario Bros. Wii, it is possible to create an infinite amount of coins. If a fence-climbing Koopa Troopa is frozen by a character with an Ice Flower or Penguin Suit, then the rotating fence activated before the frozen Koopa touches the ground, the block of ice will enter a glitchy state where it will spawn several coins every frame. If these coins are not collected quickly, the game will freeze due to being unable to display that many objects at once. Main Blog | Twitter | Patreon | Store | Source: myself, New Super Mario Bros.

Super Mario Galaxy contains models for Mario and Luigi’s skeletons, seen normally only for a few frames when they are hit by electricity. Modifying the game’s code, we can force Mario’s model to permanently change into the skeleton model. This has the side effect of allowing us to see what parts of Mario’s body that at first appear to be part of his model are actually separate objects. When Skeleton Mario picks up a Bee Mushroom, he gains wings, indicating that the wings are a different object attached to Bee Mario, not part of Bee Mario’s actual model.
