I just bought my first fire tv 3rd gen and installed retroarch and using MY OWN LEGALLY DUMPED CARTS for the games. I bought a bluetooth controller that seems to work fine. When I go to launch a game it loads up and goes through the demo but then I have no controller response at all. I have to hit the home key on my fire remote to get out and force stop retroarch. If there a fix out there for this I would much appreciate it.
