    In test mode, to test sound press 1 and 2 player start simultaneously.
    Punch + 1 player start moves to the crosshatch pattern.

    To enter test mode in Funky Fish, keep the service coin pressed while
    resetting

    TODO:
    - There is a custom MB8841 microcontroller on the original Kangaroo board which
      is not emulated. This MIGHT cause some problems, but we don't know of any.
