Hidden e-Reader Levels
Through hacking, the game has 13 e-Reader level entries, 15[citation needed] in the Japanese version, built-in. The Long Way, One Shot Blue, The Thwamplet, Danger Flowers, and Climb and Fall seem to be prototypes of The Loooong Journey, Athletic, Thwomp's Fortress, Dangerous Flower, Jump Down with Caution!. Laser Panic! doesn't seem to have a prototype level.
 e-Reader mode is normally hidden at the file select screen. |

Level Editor
Before Mario vs. Donkey Kong 2: March of the Minis, there were plans to have a level editor, but were scrapped. The code remains in the game and can be accessed by cheating. Some elements are broken and saving is not possible.
