8BitDo FC30 Pro & Rpi3
I'm tearing what little hair I have left out trying to make this thing connect and work.
I've gone through the setup and it find the controller in Bluetooth, binded the keys and they work.
But each tim I go into a game in Mame and try to insert coins it stops working.
I've watched a load of videos on youtube but they are all for the older versions of Retropie. I am on Version 4.1.16
