If function fails to find specified joystick, it will create a dummy joystick. It will represent virtual non-functional joystick. It will accept all joystick operaitons, but will not carry out any of them. Dummy joysticks do not yield any output. Function cock.reloadJoysticks will happily override dummy joysticks with real ones.
