On the World Map pause screen after finishing the game, if you press L/R/L/R/X/X/Y/Y, a secret Challenge Mode will be enabled that disables scrolling backwards in levels, making the gameplay more similar to Super Mario Bros., Super Mario Bros.: The Lost Levels, and Super Mario Land. Inputting this code again on the World Map pause screen disables this mode.

Tapping letters as the credits roll will make unique sound effects play. These effects are heard throughout the game, and each letter has its own sound (except for letters D and E, which share the same sound). The letter Q is never seen during the credits and thus has no sound.
