nCine::Backends::LibretroInputManager class

#include <nCine/Backends/Libretro/LibretroInputManager.h>

Input manager exposing the RetroPad of the frontend as a standard mapped gamepad.

The frontend provides neither a mouse nor a keyboard, every port is reported as a connected gamepad instead, so that local splitscreen multiplayer works out of the box.
