/*******************************************************************************
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.
Music (HuC6280 sound)
