Another Nintendo exclusive escapes to smartphones: New Super Mario Bros. Wii gets an unofficial port with co-op support

Another Nintendo exclusive has fallen victim to reverse engineering.

A developer known as WitherBlitz has released an unofficial Android port of New Super Mario Bros. Wii. It is a 2D platformer where Mario, Luigi, and two Toads set out to rescue Princess Peach, navigating obstacle courses, battling Bowser’s minions, and collecting power-ups. Levels can be tackled cooperatively, but teammates can also interfere with each other: bumping into one another, picking up partners, and throwing them right into danger.

The mobile version supports touch controls and four-player co-op, with smartphone and PC users running the same app version able to play together over a local network. Tailscale support is provided for connecting over the internet, though the author warns of potential connection instability.

According to the developer, the port delivers 60 FPS on tested smartphones, including the Google Pixel 3 XL with Snapdragon 845. However, stable performance across all devices is not yet guaranteed. In particular, owners of smartphones with Mali graphics report performance issues, as such chips require dedicated optimization.

Running the game requires Android 11 or newer, a 64-bit ARM processor, Vulkan support, and files from your own US copy of New Super Mario Bros. Wii with the identifier SMNE01 (first revision).
