A developer has ported Super Mario 64 to the Microsoft Zune HD, the 2009 media player that competed with the iPod. The port runs natively on the device's Nvidia Tegra APX 2600 chip using the unofficial OpenZDK homebrew kit, and it does not modify the firmware. The game renders at 480x272 in landscape, with a touchscreen overlay providing an analog stick and the standard button layout.
The build is based on sm64ex, a fork of the decompiled Super Mario 64 PC port, and requires a ROM dumped from the user's own cartridge. Game logic runs at 30 ticks per second with some lag, while audio is handled on a separate high-priority thread to avoid stutter. The developer notes that the port should be used at your own risk and has only been tested on firmware 4.5.
The technical interest lies in the graphics workarounds: the Zune's graphics driver cannot compile GLSL shaders, so the port uses prebuilt shader variants built with Nvidia's cgc and shaderfix tools, and blending is compiled into fragment shaders because the GPU lacks fixed-function blending hardware. The repo's first commit also credits Claude Opus 5.5, indicating AI assistance. The project highlights what the Zune HD could have been had Microsoft been less restrictive with third-party development, and it joins a growing list of Super Mario 64 ports to unconventional platforms.
