See this post over at
MacRumors PPC for brand-new native PowerPC Windows NT SP2 software, "WBTD.exe", compiled on and run from a real Nintendo Wii. Source included. It's attached to the comment, which could perhaps mean registering and logging in is required to download it, but I'm not sure. Try it out? Registration is free and non-intrusive anyway.
If you scroll up a bit on that thread, you will also see mention of a more up-to-date compiler for WinNT PPC, namely the same compiler, but
version 4.1 instead (AKA version 4.0
a).
By the way, it really wasn't hard to code for this at all: I actually used Visual Studio 2022 on a Windows 7 SP1 machine, then copied my C file over to the Wii, and then tried to compile that over there instead. The result? It worked without me having to do any code modifications, and without me having any familiarity with Visual C++ whatsoever. Even my C knowledge is super tiny and limited. If I can develop for this thing, ANYONE here reading this can! I really
do mean that.
You will not be able to get Windows 95 games running on it.
Overall it's great for science and a huge feat for the developer just getting it to boot. Is it usable for anything? Probably not. But it's cool!
Actually, we can. And later. Especially with some of the later versions of DirectX components that Rairii ported or brought over since. I ran Nihon Falcom's "Vantage Master Online" (English version of "Vantage Master V2") myself, thanks to it, as well as thanks to Motorola SoftWindows (wx86, linked in the thread, possibly would also have worked). Worked perfectly. If only we had sound drivers already, though!

Actually, it is: all modern CPUs have firmware-level backdoors, but all PowerPC CPUs are exempt from those (POWER9 aside), which is what the Wii, Wii U, GameCube and PowerMacs all sport (and PS3 and Xbox 360, although only 64-bit). So if networking was available, there would be higher privacy potential in having your Windows PC be your Wii or similar. WinNT 4.0 SP2 itself was also nowhere near as backdoored as later versions of Windows (if backdoored at all, but it might be, e.g. NSA key being present, as it was since later versions of Win95 onwards), so there's also some potential in that, as well.
Of course, I'd never recommend net banking on it due to exploits possible in such an old system, but then again, nothing beats in-person banking regardless of device or OS anyway. But for everything else? Go nuts!
If only we could also run Mac OS 9.2.2 and earlier on the Wii natively next! That'd be even more epic!
Anyway, all modern and even many oldschool ARM, Intel and AMD processors are all backdoored, on the other hand (Intel ME, AMD PSP etc.), and many even have undocumented CPU instructions to elevate access to root or equivalent. So having a PPC CPU for a personal system or device is one of multiple steps for taking computing into the right direction with regards to basic privacy, unlike cellphones, modern PCs and modern gaming devices (I'm looking at you, Switch 1/2, 3DS, Vita, PS4+, XBone+).
In other words, the Wii rocks, PowerPC rocks, and THIS rocks! Enjoy!
