****************************************************************************

    See also sega.c for the Sega G-80 Vector games.

    Many thanks go to Dave Fish for the fine detective work he did into the
    G-80 security chips (315-0064, 315-0070, 315-0076, 315-0082) which provided
    me with enough information to emulate those chips at runtime along with
    the 315-0062 Astro Blaster chip and the 315-0063 Space Odyssey chip.

    Special note (24-MAR-1999) - Sindbad Mystery does *not* use the standard
    G-80 security chip; rather, it uses the Sega System 1 encryption.

    Thanks also go to Paul Tonizzo, Clay Cowgill, John Bowes, and Kevin Klopp
    for all the helpful information, samples, and schematics!

    TODO:
    - locate Pig Newton cocktail mode?
    - verify Pig Newton and Sindbad Mystery DIPs
    - attempt Pig Newton, 005 sound
    - fix transparency issues (Pig Newton, Sindbad Mystery)
    - fix Space Odyssey background
    - figure out why Astro Blaster version 1 ends the game right away

    - Mike Balfour (mab22@po.cwru.edu)

    26/3/2000:  ** Darren Hatton (UKVAC) / Adrian Purser (UKVAC) **
                Added a 3rd Astro Blaster ROM set (ASTROB2).
                Updated Dip Switches to be correct for the Astro Blaster sets.
