If no custom GameControllers were provided via addCustomDevice(), any joystick device found by SDL will be used to build a default GameController device.
Otherwise the added custom device will be checked for compatibility with the provided. A match is given when the members of the SDLControllers match the base custom GameController's
Create a generic GameController device for comparison purposes.
SDL 1.2.11 can provide the attributes of a controller at runtime.
Note that this will use the first matching custom joystick provided, and exclude all other matches.
Add a an individual joystick translator for this device type.
Since it will be translated, it's safe to register the device.
No custom device match, use the comparison GameController
Set this back to NULL so we can reuse it on the next iteration.
