3. Button maps

Now we return to controller profiles. Each emulator requires its own set of controllers, each with their list of features. These are mapped to the underlying driver primitives provided by the joystick driver using a button map.

In the code, the button map is abstracted away behind a button map interface. This additional abstraction adds some code, but it allows button maps to be managed by an add-on.

The current add-on for button maps, peripheral.joystick, can only recite button maps it has been given. However, it could be made smarter by using existing button map data. For example, if the add-on knows the most popular way to map a 360 controller to a SNES controller, it can generate a SNES button map knowing only the 360 one.
