While digging around for more x86 software to test on Windows NT 4.0 PowerPC for the Wii, I stumbled upon something interesting: NT4 Visual Update.
This was a graphics mod released on a forum about 15 years ago (coincidentally on 9/11!). The original author overhauled most of NT 4.0’s icons and textures, giving the OS a facelift that looked more like Windows Vista (See pic 2 for their preview) instead of the default Windows 95 aesthetic it originally launched with back in 1996. The original download links were long since dead, but I luckily managed to track down a working download through archive.org.
There was just one snag: the mod requires Service Pack 3, which the PowerPC build of NT 4.0 never received since it stopped getting updates after SP2. While x86 programs can technically run under Motorola SoftWindows 32, emulation only gets you so far before errors and compatibility quirks start appearing. From my testing, installing components like Microsoft Visual Basic 5.0 seem to improve x86 program support on the machine, but those benefits also hit a ceiling since newer revisions often expect later Service Packs that PPC NT simply doesn’t have.
Since the installer wouldn’t even run on the OS (and there weren’t any compatible binary editors for NT 4.0 PPC), I had to get creative. Using Resource Hacker, I manually ported the updated assets into NT 4.0 one by one. It was a tedious process, and some assets weren’t injected since NT 4.0 PPC SP2 was missing certain functions and callbacks. However, enough of them worked to bring the OS closer to that Vista look the mod was going for.
Since NT 4.0 supports TrueColor, you can actually drop in most of the Windows Vista wallpapers and they’ll display with full color just fine, icons too. By setting the login background to pure black (0,0,0) in the registry editor and swapping out the default NT 4.0 boot graphic with a custom .BMP of your desired wallpaper in 640 x 480, also via a quick registry edit, the entire login process starts to feel much closer to the “Vista spirit.” Since Windows 7 is the sleeker, more beloved evolution of Vista, I swapped in a Windows 7 wallpaper for both the desktop and login screen.
All of that being said, keep in mind this setup is not perfect. It’s more like a bunch of gum, duct tape, and spit holding the whole thing together. In spite of that, this still manages to pull off a convincing illusion and cozy vibe of the Aero era that newer OS's don't have.
TL;DR
>dug up an old NT4 to Vista skin pack (dead links, found it on archive.org)
>needs SP3, which NT 4.0 PPC doesn’t have
>manually hacked the assets in with Resource Hacker
>used TrueColor + custom wallpapers, and cobbled together a fake “Vista/7” vibe. >it’s hacky, but it works and feels comfy
This is compatible on the Gamecube and Wii U as they also have the Windows NT homebrew program.
