New Super Mario Bros. Wii

New Super Mario Bros. Wii is a side-scrolling platform video game published and developed by Nintendo for the Wii. It is the first game in the Mario main series since the Mario Bros. arcade game to feature simultaneous multiplayer gameplay, and the first title to include Nintendo's new 'Super Guide' feature. The game’s plot is similar to those of other side-scrolling Mario games. 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. While traveling through up to nine worlds with a total of 88 levels, Mario must defeat Bowser's children, the Koopalings and Bowser Jr., and Bowser himself before finally saving Princess Peach.

IR > 1x Banding/Pixelated Shading
At higher internal resolutions, shading will look weird by default, almost as if it's pixelated. Turn on "Force Texture Filtering" to resolve this.
