Saturn-DaemonbitePCB_MISTER
Uses Authentic Saturn controller ports from a Sega Saturn along with MickGyver's Daemonbite firmware to use a Sega Saturn controller with MISTER FPGA. You will need an Arduino PRO micro.
Take the ZIP file to your favorite fab house such as JLCPCB.
V2 will likely have a version with cannibalized extension port cable connector. Until suitable springs can be used on a card edge connector this will have to do.
Any other questions @ me on twitter. @cyothevile
Soon I will have photo of it assembled.
