- * Using the SDL_HINT_GAMECONTROLLERCONFIG hint or the SDL_GameControllerAddMapping you can add support for controllers SDL is unaware of or cause an existing controller to have a different binding. The format is:
- * guid,name,mappings
- *
- * Where GUID is the string value from SDL_JoystickGetGUIDString(), name is the human readable string for the device and mappings are controller mappings to joystick ones.
- * Under Windows there is a reserved GUID of "xinput" that covers any XInput devices.
- * The mapping format for joystick is:
- * bX - a joystick button, index X
- * hX.Y - hat X with value Y
- * aX - axis X of the joystick
- * Buttons can be used as a controller axis and vice versa.
- *
