Modders Install Windows NT 4.0 on Nintendo GameCube
Hobbyists have installed the 1990s-era Windows NT 4.0 operating system on Nintendo's GameCube using its PowerPC architecture, as shown in new modding videos.
The project traces back to last year when a new build of Windows NT for PowerPC emerged. Because the GameCube and Wii share a similar PowerPC architecture, modders were able to adapt the operating system to run on the console. While practical uses remain limited, the effort demonstrates the advanced capabilities of the modding community.
In February 2025, YouTube creator emu_kidid released a video showing the software-side installation process. This year, Jiga Tech and Michael MJD posted videos focusing on the hardware side. Their method requires removing the GameCube's disc drive, installing a mod drive in its place, and booting the system using an SD card hidden inside a memory card adapter. Both modders got the system running; Michael MJD played Solitaire, while Jiga Tech managed to get the ASCII GameCube keyboard controller and, to a degree, the DK Bongo controller working.
The GameCube's continued relevance in modding stems from its shared hardware with the Wii, which makes such experiments feasible. The growing popularity of modding older consoles also reflects how Nintendo's aggressive legal approach against modifications on current systems has driven enthusiasts to vintage hardware, where they can freely assert control over the technology they own.
