An Open-Source HardWare (OSHW) Famicom expansion audio interfacer.
Currently a work in progress, completed but untested!!! 28/FEB/2023: this repo is now archived, i may have to start from scratch with what i learned since i started this.
Note that this project is optimized for JLCPCB manufacturing, so you may have to modify the gerber export, remove the "JLCJLCJLCJLC" silkscreen text, etc. Please use the gerber exports in each release.
