      N.Y. Captor - Taito '85
  
       Driver by Tomasz Slanina
  ****************************************************************************
    Hardware similar to Fairyland Story
    Cycle Shooting (Taito '86) is running on (almost) the same hardware
    as NY Captor, but MCU dump is missing.
  
  
  What's new :
   - added bootlegs - Bronx and Colt
   - Cycle Shooting added (bigger VRAM than nycpator, different (unknown yet) banking and
     gfx control , ROMs probably are wrong mapped, gfx too)
   - Sub CPU halt (cpu #0 ,$d001)
   - Improved communication between main cpu and sound cpu ($d400 cpu#0 , $d000 sound cpu)
  
  
  To do :
   - REAL bg/sprite priority system
   - cpu #0 , $d806 - only bits 0,1,2 used , something with sound control
                      (code at $62x)
   - better sound emulation (mixing ?)
   - unknown R/W
   - 13th bit in color defs (priority? bit is set for all colors in spot1,
                             for 3/4 screen cols in spot2 etc)
   - handle coin counters and coin lockout

  Stephh's additional notes (based on the game Z80 code and some tests) :
  
  1) 'nycaptor' and clones
  
  1a) 'nycaptor'
  
    - You need to press SERVICE1 while resetting the game to enter the "test mode".
      Note that the grid is always displayed, so it's IMPOSSIBLE to see what's in it 8(
    - When "Infinite Bullets" is set to ON, there is no timer to reload the bullets.
    - When "No Hit" Dip Switch is ON, damage is still incremented, but there are
      no test made if it reaches the limit (0x0a).
    - DSWC bit 2 also determines the precision of a shot
      (= range around a bullet where the enemies can be killed) :
        * 0 : small range (0x0a or 0x10)
        * 1 : high  range (0x0c or 0x12)
    - Even when "Coin Slots" is set to "1", pressing COIN2 will be based on "Coin B" settings.
  
  1b) 'colt'
  
    - Due to patched code at 0x9fd, lives (BCD coded) settings are different than in 'nycaptor'.
      Display at start will be lives-1, but it will also display "0" when you select 100 lives.
    - The game is much harder than 'nycaptor' :
        * Due to the 4 'nop' instructions at 0x0b03, you can't get any extra life.
        * Due to patched code from 0x0bea to 0x0bf4, you lose a life as soon as you get hit
          by en enemy or when you shoot at an innocent.
          Furthermore, shooting birds kills you instead of recovering 3 "steps" of damage !
    - I can't tell if it's an ingame bug of this bootleg, but the game hangs after bonus stage
      (level 4) instead of looping back to level 1 with higher difficulty.
      The game also freezes sometimes for some unknown reasons.
  
  2) 'cyclshtg' and clones
  
  2a) 'cyclshtg'
  
    - Lives (BCD coded) settings are not read from MCU, but from table at 0x0fee.
    - Even if it isn't mentioned in the manual, DSWB bit 7 allows you to reset damage to 0
      at the end of a level (check code at 0x328d).
    - When "Infinite Bullets" is set to ON, there is no timer to reload the bullets.
      However, it's hard to notice as you don't see an indicator as in 'nycaptor'.
    - There is a leftover from 'nycaptor' in CPU1 which reads DSWA bits 0 and 1 to determine
      "Bonus Lives" settings (code at 0x009b). These values are overwritten via code in CPU 0.
  
  2b) 'bronx'
  
    - Lives (BCD coded) settings are different than in 'cyclshtg' (table at 0x0fea).
    - The game is much harder than 'cyclshtg' :
        * You start with less lives with default settings (2 instead of 3).
        * Due to the 'add  a,$00' instruction at 0x1131, you can't get any extra life
          (when you get enough points, or even when you hit the "1UP" bonus).
        * Due to extra code at 0x3062, you start the game as if you had already sustained
          8 "steps" of damage. However, when you end a level, if "Damage Reset" Dip Switch
          is ON, your damage will be reset to 0.
          Furthermore, the game starts as if you had completed the 6 stages 8 times.
        * Due to the 'ld   (ix+$0e),$08' instruction at 0x32b1, you also start the
          other lives as if you had already sustained 8 "steps" of damage. However, again,
          when you end a level, if "Damage Reset" Dip Switch is ON, your damage will be reset to 0.
