    TODO:
    - PAL is presumably inverted with address bit 11 (0x800) for 0x6000-0x7fff area
      between Libble Rabble and Toy Pop.
    - Proper sprite DMA.
    - Flip Screen;
    - Remaining outputs;

    Notes:
    ------
    - Libble Rabble Easter egg:
     - enter service mode
     - turn off the service mode switch, and turn it on again quickly to remain
       on the monitor test grid
     - Enter the following sequence using the right joystick:
       9xU 2xR 9xD 2xL
