Throaty Mumbo successfully ran Windows CE 2.11 on the Nintendo 64 by leveraging the shared architecture of both systems, which are based on the MIPS R4000 processor family. The project involved a month of reverse engineering, using Microsoft toolchains, custom hardware modifications, and debugging techniques. An EverDrive flash cartridge was used to load custom ROMs, and a USB connection facilitated uploads from a PC. Challenges included crashes with the initial EverDrive cartridge, which were resolved by upgrading to the EverDrive-64 X7. A custom kernel clone was created to troubleshoot issues with the stock Windows CE kernel, ultimately allowing the project to revert to the unmodified version. The Nintendo 64 controller was repurposed as a mouse, and standard Windows CE applications could be launched from the desktop. Comprehensive build details are available on GitHub.
