@krullbeast more specifically, can i map the nunchuck(as a directional pad also) C and Z buttons as select and start in emulation station or retroarch AND also have two seperate A and B buttons wired to GPIO pins on my Pi 3b? will they all communicate with the Pi? or will the A and B buttons not work after enabling 12c serial at start up?
i am very new to this, please forgive me if i sound stupid.
and thank you for any advice this is a rough schematic of what i'm trying to build
