Difference between Twin Cobra and Kyukyoku Tiger:
    T.C. supports two simultaneous players.
    K.T. supports two players, but only one at a time.
         for this reason, it also supports Table Top cabinets.
    T.C. stores 3 characters for high scores.
    K.T. stores 6 characters for high scores.
    T.C. heroes are Red and Blue for player 1 and 2 respectively.
    K.T. heroes are grey for both players.
    T.C. dead remains of ground tanks are circular.
    K.T. dead remains of ground tanks always vary in shape.
    T.C. does not use DSW1-1 and DSW2-8.
    K.T. uses DSW1-1 for cabinet type, and DSW2-8 for allow game continue.
    T.C. continues new hero and continued game at current position.
    K.T. continues new hero and continued game at predefined positions.
         After dying, and your new hero appears, if you do not travel more
         than your helicopter length forward, you are penalised and moved
         back further when your next hero appears.
    K.T. Due to this difference in continue sequence, Kyukyoku Tiger is MUCH
         harder, challenging, and nearly impossible to complete !


Stephh's notes (based on the games M68000 and Z80 code and some tests) :

1) 'twincobr' and "clones"

  - There is no real "test mode" : only a grid with colors ("Cross Hatch Pattern")
    is displayed. There is a separate "Dip Switch Display".

1a) 'twincobr'

  - No notice screen.
  - Game uses TOAPLAN_COINAGE_WORLD (code at 0x0bfd in CPU1).
  - Press any players buttons on startup to skip some tests (code at 0x025ed8).

1b) 'twincobru'

  - "FOR USE IN U.S.A. ONLY" notice screen.
  - Game uses TOAPLAN_COINAGE_JAPAN (code at 0x0bfd in CPU1).
  - Press any players buttons on startup to skip some tests (code at 0x025ed6).

1c) 'ktiger'

  - "FOR USE IN JAPAN ONLY" notice screen.
  - Game uses TOAPLAN_COINAGE_JAPAN (code at 0x0bfd in CPU1 - same as in 'twincobru').
  - Press any players buttons on startup to skip some tests (code at 0x0259d0).
  - "Bonus Lives" settings are different than the ones in the other sets.
  - See other differences with 'twincobr' and 'twincobru' above.

1d) 'gulfwar2'

  - No notice screen.
  - Game uses TOAPLAN_COINAGE_JAPAN (code at 0x0bfd in CPU1 - same as in 'twincobru').
    Surprisingly, when Dip Switches are displayed, it shows TOAPLAN_COINAGE_WORLD.
  - Press any players buttons on startup to skip some tests (code at 0x025ed8).
  - VBLANK bit is inverted (ACTIVE_LOW instead of ACTIVE_HIGH).


2) 'fshark' and "clones"

  - There is no real "test mode" : only a grid with colors ("Cross Hatch Pattern")
    is displayed. There is a separate "Dip Switch Display".

2a) 'fshark'

  - No notice screen.
  - Game uses TOAPLAN_COINAGE_WORLD.
  - When cabinet set to "Upright", you can use joystick and buttons from both players
    (code at 0x002434).

2b) 'skyshark'

  - "FOR USE IN U.S.A. ONLY" notice screen.
  - Game uses a unique coinage.
  - When cabinet set to "Upright", you can use joystick and buttons from both players
    (code at 0x002436).

2c) 'hishouza'

  - "FOR USE IN JAPAN ONLY" notice screen.
  - Game uses TOAPLAN_COINAGE_JAPAN.
  - When cabinet set to "Upright", you can use joystick and buttons from both players
    (code at 0x002456).

2d) 'fsharkbt'

  - This bootleg is heavily based on 'skyshark', so they share the same infos.
    However, the values written to the DSP (0x030004) are the same as in 'hishouza'
    and the chars ROMS (gfx1) are the same as in 'fshark' !

Only the first two lines of the MCU label seem to be significant;
Flying Shark, Sky Shark and Wardner MCUs are all interchangeable.
Demon's World also uses an MCU interchangeable with Twin Cobra.

68K writes the following to $30000 to tell DSP to do the following:
Twin  Kyukyoku
