    Space Firebird hardware

    Memory Map figured out by Chris Hardy, Paul Johnson and Andy Clark
    MAME driver by Chris Hardy

    Schematics scanned and provided by James Twine
    Thanks to Gary Walton for lending me his REAL Space Firebird

    There is an undumped bootleg of this named 'Fire Condor', see
    http://solarfox.triluminary.net/arc_spacefirebird.php for info

    Known issues/to-do's:
        * Bullet colors are incorrect.  The schematics cannot be right, so
          I am using pure red for now

          "MAME has the bullets and missiles as red, the real pcb shows them as
           yellow with red tinges, they are overall yellow/orange in appearance."
           (Andrew Welburn 24/12/10)

        * Analog sounds


    0000-3FFF ROM       Code
    8000-83FF RAM       Sprite RAM
    C000-C7FF RAM       Game RAM

    IO Ports

    IN:
    Port 0

       bit 0 = Player 1 Right

       bit 1 = Player 2 Left
       bit 2 = unused
       bit 3 = unused
       bit 4 = Player 2 Warp / Escape
       bit 5 = unused

    Port 2

       bit 0 = unused
       bit 1 = unused
       bit 2 = Start 1 Player game
       bit 3 = Start 2 Players game
       bit 4 = unused

       bit 7 = Coin and Service switch

    Port 3

       bit 1 = Dipswitch 2
       bit 2 = Dipswitch 3
       bit 3 = Dipswitch 4
       bit 4 = Dipswitch 5
       bit 5 = Dipswitch 6
       bit 6 = unused (Debug switch - Code jumps to $3800 on reset if on)
       bit 7 = unused

   OUT:
   Port 0 - Video

       bit 0 = Screen flip. (RV)
       bit 1 = unused
       bit 2 = unused
       bit 3 = unused
       bit 4 = unused
       bit 5 = Char/Sprite Bank switch (VREF)
       bit 6 = Turns on Bit 2 of the color PROM. Used to change the bird colors. (CREF)
       bit 7 = unused

   Port 1
       bit 0 = discrete sound (Enemy death)
       bit 1 = INT to 8035
       bit 2 = T1 input to 8035
       bit 3 = PB4 input to 8035

       bit 5 = T0 input to 8035
       bit 6 = discrete sound (Ship fire)
       bit 7 = discrete sound (Explosion noise)

   Port 2 - Video control

      These are passed to the sound board and are used to produce a
      red flash effect when you die.

      bit 0 = CONT R       Changes contrast of the red/green/blue part of the stars. This is used to make the starfield flicker
      bit 1 = CONT G
      bit 2 = CONT B
      bit 3 = ALRD         Turns background red on
      bit 4 = ALBU         Turns background blue on
      bit 5 = unused
      bit 6 = unused
      bit 7 = ALBA         Turns off star field (no star field)
