Game Dodecahedron Runs Bare-Metal Pi 3 Code

From a retro gaming angle, this is the sort of build that gets attention in the UK scene and beyond. The Game Dodecahedron is a DIY console based on a Raspberry Pi 3, and it runs bare-metal AArch64 assembly games from custom SD card cartridges.

Creator [Inkbox] built the system, as detailed on Hackaday, using a Raspberry Pi 3 that had been sitting unused since 2016. The aim was to program games directly to hardware, in the spirit of early console development, including the approach Masayuki Uemura intended for the NES.

The console itself is a dodecahedron, a twelve-sided shape, which makes it stand out from the usual boxy hardware. It is a physical build with a strong homebrew feel, and it leans into the kind of design choices that retro fans tend to appreciate.

The technical hook is the bare-metal setup. Instead of running a full operating system, the Game Dodecahedron sends games straight to the hardware in AArch64 assembly. The creator even programmed a version of Pac-Man for it, which shows how far the project pushes the Raspberry Pi 3.

The cartridge idea is part of the appeal too. These are adapted SD cards mounted on large printed circuit boards, giving the system a classic console feel without pretending to be original factory media. The creator also made a RetroPie cartridge, loaded with emulators, and the source suggests that will likely be its main use.

For readers who follow homebrew and modding, this is less about resale value and more about craft. It is a one-off build that puts direct hardware control front and centre, and it is a reminder that low-level game programming still has a place in modern DIY projects.
