    Driver by Bryan McPhail and David Haywood.

    Todo:
        Sprite priorities aren't verified to be 100% accurate.
        There may be some kind of fullscreen palette effect (controlled by bit 3 in priority
        word - used at end of each level, and on final boss).
        A shadow effect (used in level 1) is not implemented.
