Old Gameboy Shell As USB C Rechargeable Controller
Still very much a work in progress but it works reasonably well (about 8ms of lag). I want to ultimately create an easier to install PCB rather than the perfboard I used.
Thanks. I was looking at these carts and thought about hard it would be to make something similar that you could use a old shell with. I recently made a SNES to Bluetooth adapter so the code was pretty similar. I really like projects that recycle parts like this.
