Innovative Hacking: Running Windows CE on Nintendo 64
In the realm of creative technology, the act of hacking often transcends mere necessity, venturing into the exhilarating territory of pushing hardware to its limits. This is vividly illustrated by the latest endeavor from Throaty Mumbo, who has taken on the challenge of running Windows CE on the Nintendo 64—a feat that many would deem unnecessary, especially when the console is better known for classic titles like GoldenEye 007.
The motivation behind this unconventional project lies in the shared architecture between Microsoft’s Windows CE 2.11 and the Nintendo 64’s NEC VR4300 CPU, both of which are rooted in the MIPS R4000 processor family. This compatibility opened the door for the possibility of booting the operating system on the beloved gaming console, provided that the right hardware abstraction layer and drivers could be developed.
The journey to achieve this ambitious goal unfolded over a month of intense reverse engineering, utilizing a blend of antiquated Microsoft toolchains, custom hardware modifications, and meticulous debugging. Throaty Mumbo navigated the challenges posed by the original Windows CE development tools, which were designed for systems running Windows NT 4.0. To bridge this gap, he employed Wine configured for NT compatibility within a Linux environment to compile the necessary software.
To facilitate the testing process, the Nintendo 64 was integrated into a modern automated testing setup. An EverDrive flash cartridge enabled the loading of custom ROMs directly from an SD card, while a USB connection allowed for seamless uploads of new builds from a PC. In a clever twist, Throaty Mumbo soldered wires to the console’s reset button, enabling remote reboots after each compilation cycle.
As with any ambitious tech project, obstacles were inevitable. The EverDrive cartridge initially caused perplexing crashes during ROM-to-RAM transfers, prompting an upgrade to the newer EverDrive-64 X7, which boasted open-source firmware and enhanced debugging capabilities. At one juncture, the stock Windows CE kernel became a daunting black box, leading Throaty Mumbo to create a custom kernel clone to trace hardware initialization and pinpoint the source of the system hang-ups. Ultimately, the issue was resolved, allowing the project to revert to Microsoft’s unmodified Windows CE 2.11 kernel.
With the technical hurdles addressed, the Nintendo 64 controller transformed into a functional mouse, the EverDrive’s SD card served as storage, and audio output utilized the console’s native hardware. Standard Windows CE applications, including Paint and Notepad, could be launched directly from the desktop, showcasing the versatility of this unexpected port.
While the majority may find satisfaction in simply watching the demonstration of this innovative setup, those intrigued by the prospect of running Windows CE on their own Nintendo 64 can find comprehensive build details available on GitHub.
