Even more vintage: releasing music on a custom-built Game Boy cartridge!
summary
Project builds a custom Game Boy cartridge that plays a full album as CD-quality audio by putting a modern MCU (an STM32F4 at 180 MHz) and flash on the cartridge, using the Game Boy’s unused audio-in pin and a memory-mapped protocol to switch tracks; Super Mario Land is stripped of its audio and re-skinned to select songs. Toolchain includes C, Python, Makefiles, KiCad and a PCB run that produces five boards with four of five boards worked, and the cartridges play the pusher album.
