DU Faith Genesis Raven from the DarkUmbra team created the Super Mario Bros: 2.1 Madness Returns hack, which is based on the New Super Mario Bros. Wii video game.
When Mario first enters the game, he finds himself in front of a large, dark mansion that is located on the outskirts of a forest. Toads, who make their home in a modest workshop adjacent to the mansion, are conducting research on the mansion, which is said to be haunted by a number of ghosts, among which are Boos. WHAT IN THE WORLD HAVE YOU DONE, MARIO?
