/***************************************************************************
VIC Dual Game board
Games supported:
* Depth Charge
* Sub Hunter
* Safari
* Frogs
* Space Attack
* Space Attack / Head On
* Head On
* Head On 2
* Invinco / Head On 2
* N-Sub
* Samurai
* Invinco
* Invinco / Deep Scan
* Tranquillizer Gun
* Space Trek
* Carnival
* Borderline
* Digger
* Pulsar
* Heiankyo Alien
* Alpha Fighter / Head On
* and a few clones and bootlegs
Notes:
* Head On and Space Attack had both color and monochrome
versions. There is a game configuration option to
switch between them.
* There existed a vertical version of Head On as well.
* According to the manuals, Borderline has the same sound
board as Tranquillizer Gun.
* The relationship between nostromo and startrks isn't clear:
is one a bootleg of the other or are both bootlegs of an unknown
original?
Known issues/to-do's:
* Analog sound missing in many games
* Missing color PROM for "Alpha Fighter / Head On"
* A few of the games have an extra 18K pull-up resistor on the
blue color gun, Carnival, for example.
Colors inaccurate? Blue background?
* Do other games have coinage hardware like nsub?
brdrline and tranqgun have one too according to the manuals,
but hardware details aren't known yet.
* DIP switches need verifying in most of the games
* DIP switch locations need to be added to some
