        ToaPlan game hardware from 1987
        -------------------------------
        Driver by: Quench
        Flying Shark details: Carl-Henrik Skarstedt  &  Magnus Danielsson
        Flying Shark bootleg info: Ruben Panossian


Supported games:

    Toaplan Board Number:   TP-007
    Taito game number:      B02
        Flying Shark (World)
        Sky Shark (USA Romstar license)
        Hishou Zame (Flying Shark Japan license)
        Flying Shark bootleg (USA Romstar license)

    Toaplan Board Number:   TP-011
    Taito game number:      B30
        Twin Cobra (World)
        Twin Cobra (USA license)
        Kyukyoku Tiger (Japan license)

    Comad Board Number:     ??????
    Comad game number:      ???
        GulfWar II (Game play very similar to Twin cobra)

Difference between Twin Cobra and Kyukyoko 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. heros are Red and Blue for player 1 and 2 respectively.
    K.T. heros 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, Kyukyoko Tiger is MUCH
         harder, challenging, and nearly impossible to complete !

7e000-7e005 read data from video RAM (see below)

write:
60000-60003 CRT 6845 controller. 0 = register offset , 2 = register data
70000-70001 scroll   y   for character page (centre normally 0x01c9)

76000-76003 as above but for another layer maybe ??? (Not used here)
7800a       This activates INT line for Flying shark. (Not via 7800C)
            00      Activate INTerrupt line to the TMS320C10 DSP.
            01      Inhibit  INTerrupt line to the TMS320C10 DSP.

            bits 7-4 always 0
            bits 3-1 select the control signal to drive.
            bit   0  is the value passed to the control signal.

            Value (hex):
            00-03   ????
            04      Clear IPL2 line to 68000 inactive hi (Interrupt priority 4)
