Nintendo GameCube modified to run PowerPC Windows NT and Doom

Earlier this month, a brand-new build of the long-deprecated Windows NT for PowerPC surfaced. It's now optimized for the Nintendo GameCube and Wii families of Nintendo consoles, of all platforms, thanks to their reliance on PowerPC architecture supported by the original Windows NT PowerPC releases. This build, called Entii for WorkCubes and on GitHub, also technically has Wii U support, but not in a sense that utilizes its two extra PowerPC cores, higher RAM pool, or more powerful AMD GPU— only through the virtualized Wii function. Early dev boards are either unsupported entirely or "theoretically" supported but not tested.

Fortunately for homebrew enthusiasts interested in seeing this Windows NT software run on a Nintendo GameCube, YouTuber @emukid_id has recorded footage of the Windows NT installation process, some basic use, and even some incredibly low-resolution (320 x 200!) The Ultimate Doom gameplay. Unfortunately, there is no sound in any of these videos.

    The article said:
    Unfortunately, there is definitely some compromise here—but even a user employing a standard Windows NT PC here in 2025 would be unlikely to find any usable web pages on the modern Internet. Even if compatibility with GameCube or Wii's Ethernet adapters is intact, online uses would seem supremely limited.
    If it had proper GPU drivers, this could provide a good avenue for people to develop homebrew games for GameCube/NT. Yes, the GPUs don't support most modern features, but at least you could use PC development toolchains and libraries of the era.

    I think Linux is a better avenue, because you actually could run newer kernels and software on it, but I do think this NT hack is cool.

    But aside from lacking sound Windows 95 largely seems to work as expected
    What is "Windows 95" doing here? NT is completely different to 95.

    However, the system can still be a snapshot of Windows NT and PowerPC in the pre-Windows NT 3.5 days of PowerPC support on Windows...
    ...
    Proper Wii U support for NT 3.5 or a later version of Windows could up the ante...
    Wha...? This is Windows NT 4.0 already; going back to 3.5 or 3.1 would be pointless.

    Articles like these remind me a lot at what was published at anandtech its last 1-2 years - the article seems more or less just rephrased from somewhere else and a bit augmented with seemingly inconsistent/wrong information (windows 95, pre NT 3.5 comments).

    Can't wait to read the next "Raspberry PI turned into XYZ" article.
