Mario Kart Wii is an unreleased enhanced port of the original Wii game, specifically designed for the Nvidia Shield console. This version aimed to offer an improved gaming experience by supporting 1080p resolution and adapting gameplay mechanics to eliminate the reliance on motion controls. This adaptation allows players to enjoy the classic racing game in a more traditional format while maintaining the engaging elements that fans expect from the franchise.

Part of a collaboration between Nintendo and Nvidia, this port was developed using a special version of the Dolphin emulator, enabling the necessary modifications. Although it was part of a series of Nintendo titles intended for release in China, this particular version of Mario Kart Wii ultimately never saw the light of day, leaving fans anticipating what could have been an exciting addition to their gaming library.
