    Battle Rangers                  (c) 1988 Data East Corporation
    Bloody Wolf                     (c) 1988 Data East USA

    Emulation by Bryan McPhail, mish@tendril.co.uk

    This board is a modified PC-Engine PCB, differences from PC-Engine console:

    Input ports are different (2 dips, 2 joysticks, 1 coin port)
    _Interface_ to palette chip is different, palette data is the same.
    Extra sound chips, and extra processor to drive them.
    Twice as much VRAM.

    Todo:
    - Priority is wrong for the submarine at the end of level 1.
    - There seems to be a bug with a stuck note from the YM2203 FM channel
      at the start of scene 3 and near the ending when your characters are
      flying over a forest in a helicopter.
