New Super Mario Bros. Wii gets a native Windows recompilation with 8x resolution and 180 fps

NSMBWiicompiled turns the 2009 Wii platformer into a native Windows program through static recompilation, adding widescreen at up to 8x resolution, frame interpolation, HD texture packs and four-player gamepad support.

New Super Mario Bros. Wii now runs as a regular Windows application, without an emulator. The project, called NSMBWiicompiled and made by ral1009, is a static recompilation: the game's PowerPC code is converted ahead of time into a native PC program, while the levels, graphics and sound are read from the player's own disc. The latest release, version 0.2.2, came out on November 7, 2026, and the author reports more than a thousand downloads so far.

Nintendo released the original on the Wii in 2009. It brought four-player simultaneous play to a 2D Mario game for the first time, along with new power-ups such as the Propeller Suit and the Penguin Suit.

What it does

The game can render at up to eight times the Wii's resolution in 16:9, while its logic keeps the original 60 fps timing. Optional frame interpolation generates extra frames for 120 or 180 fps displays, though the two highest resolution settings are off while interpolation is enabled. Existing Dolphin HD texture packs for the game work unchanged and can be toggled during play.

Settings live in a new options menu built from the game's own windows, fonts and sounds, opened with F10 or from the pause and map menus. It covers display mode, resolution, bloom, separate audio volumes and controls.

Controls and multiplayer

Any gamepad supported by SDL works, as does the keyboard, and buttons can be bound separately for levels, the world map and menus, including button combinations. On-screen prompts change to match the controller in use. Up to four players can join, each on a gamepad, or several on one keyboard. A few quality-of-life tweaks are included too: a full save from the world map at any point, an Exit option in courses that haven't been cleared, and skippable intro and hint movies. Wii Remote input is not supported.

What you need

The download contains no game data. Players need their own copy of the European (PAL) disc, revision 1 (SMNP01); the US version does not work. The port requires 64-bit Windows 10 or 11, a processor with AVX2 and a GPU with Direct3D 12 or Vulkan. It builds on the WiiCompiled recompilation of Mario Kart Wii and the aurora graphics layer, and the author describes it as a high-school learning project written with AI assistance.

What's next

Planned work includes support for other versions of the game, lower hardware requirements, Linux, Mac and Android builds, and character selection for player one.

To try it, follow the instructions on the official GitHub page with your own copy of the game.
