Hello at all,
i am new in the retroarch world 
I really enjoy the RetroArch project on my fire tv box so far. super nintendo games are running great with the fire tv gamepad. Now i wanted to try a few n64 classics. for a better n64 feeling i would try a controller with the typical n64 layout (via usb connection).
is it possible to use such a controller including configuration (z button) stuff?
As i tried the input mapping config for the amazon fire tv gamepad, i had no message to configure the z button mapping (maybe because the fire tv gamepad does not have the related unmapped button)
thanks alot for clearing this question…
