 Super Cobra hardware

NOTE:  Eventually to be merged into GALAXIAN.C

TODO:
----

- Need correct color PROMs for Super Bond

- Dark Planet background graphics

- Explosion sound in Scramble/Super Cobra repeats

- Armored Car probably has some other effect(s) during an explosion.
  It uses both POUT1 and POUT2.


Notes/Tidbits:
-------------

- Armored Car sets Port C as well, but it's input only and the games uses other
  bits for the 2nd player controls.  Maybe the games was meant to use 2 joysticks
  at one time.

- Video Hustler and its two bootlegs all have identical code, the only
  differences are the title, copyright removed, different encryptions or
  no encryption, plus hustlerb has a different memory map.

- In Tazmania, when set to Upright mode, player 2 left skips the current
  level
