New Super Mario Bros. Wii is a 2009 side-scrolling platform video game developed and published by Nintendo for the Wii video game console. New Super Mario Bros. Wii follows Mario as he fights his way through Bowser's henchmen to rescue Princess Peach. Mario has access to several power-ups that help him complete his quest, including the Ice Flower, the Fire Flower, and the Starman, each giving him unique abilities. There are some new powerups to this game, such as the Propeller Hat which lets the player ascend very quickly.

The authors improve upon the previous publication by 33.9 seconds. Many changes have been made to the route where the propeller mushroom has been swapped out with the ice flower and penguin suit, which provide overall faster horizontal speeds. We recommend reading the submission notes for more information on the changes.
