Nintendo GameCube Converted to Run PowerPC Windows NT and Play Doom

Earlier this month, an intriguing new version of the long-abandoned Windows NT tailored for PowerPC architecture made its appearance. This version has surprisingly been optimized for Nintendo’s GameCube and Wii consoles, which are powered by similar PowerPC technology as the original Windows NT releases. Dubbed “Entii for WorkCubes” and available on GitHub, this build also technically supports the Wii U. However, it doesn’t take full advantage of the Wii U’s additional PowerPC cores, larger RAM capacity, or its superior AMD GPU, relying instead on the Wii’s virtual console function. Unfortunately, early development boards are either not supported or only theoretically so, as they haven’t been thoroughly tested.

For those interested in the homebrew scene and curious about how Windows NT runs on a GameCube, YouTuber @emukid_id has showcased the installation process, some basic operations, and even some gameplay from The Ultimate Doom at an incredibly low 320 x 200 resolution. Sadly, the video lacks sound.

Despite this, the Windows 95 functionality on this setup is surprisingly reliable. You can configure classic NT wallpapers like the 3D Maze, use Notepad, and access the basic Internet Explorer homepage. The system also supports a variety of peripherals more akin to PCs, such as GameCube controllers that double as oversized keyboards, turning the handles into distant controls. Meanwhile, the standard USB ports on the Wii and Wii U facilitate the connection of different USB devices.

While there are limitations—modern web browsing is virtually impractical even with compatibility for GameCube or Wii Ethernet adapters—this setup acts as a fascinating snapshot of the old PowerPC days before Windows NT 3.5. You can still play Doom on the GameCube, which is quite impressive. The Wii, being a souped-up GameCube with enhanced processing and graphics capabilities, runs it even better.

If a version of NT 3.5—or something newer—could be adapted for the Wii U, it could leverage its more substantial 1GB of DDR3 RAM and its three-core PowerPC CPU, making it a powerhouse compared to the single-core systems of the GameCube and Wii. The GameCube, remember, operated on only 24MB of system RAM but had additional small RAM allocations for video and I/O components.
