+Blood Bros, West Story [+Sky Smasher]
+TAD Corporation 1990
+68000 + Z80 + YM3931 + YM3812
+
+driver by Carlos A. Lozano Baides
+
+Coin inputs are handled by the sound CPU, so they don't work with sound
+disabled. Use the service switch instead.
+
+TODO:
+West Story:
+- sound
+- some bad sprites, probably bad ROMs.
+- tilemap scroll
+
+
+Sky Smasher (c) 1990 Nihon System [Seibu hardware]
+-----------
+
+Like some other Seibu hardware games, hold P1 right at boot to
+view DIP descriptions.
+
+Game does not appear to have cocktail mode. The screen hardware
+is undoubtedly capable of flipscreen and layer priority flipping
+however.(which is why we have GAME_NO_COCKTAIL despite the games
+being upright)
+
+Dumpers Notes
+=============
+
+PCB is made by Seibu
+
+Sound - Z80
+ - YM3931 SEI0100BU (64 pin DIP)
+ - YM3812
+ - M6295
+
+GFX - SEI0210 custom (128 pin PQFP)
+ - SEI0220BP custom (80 pin PQFP)
+ - SEI0200 custom (100 pin PQFP)
+ - SEI0160 custom (60 pin PQFP)
+
+
+Stephh's notes (based on the games M68000 code and some tests) :
+
+1) 'bloodbro'
+
+ - When "Starting Coin" Dip Switch is set to "x2", you need 2 coins to start
+ a game (but 1 coin to join), then 1 coin to continue.
+ However, it you insert 2 coins, and press START2, you start a 2 players game.
+ Also note that when "Starting Coin" Dip Switch is set to "x2", SERVICE1
+ adds 2 credits instead of 1.
+
+ - Bits 6 and 7 of DSW are told to be unused, but they are tested before
+ entering the initials (code at 0x004a1e, 0x014bb0 and 0x014c84)
+
+
+2) 'weststry'
+
+ - This bootleg has been realised by Datsu in 1991. This "company" also
+ bootlegged "Toki" (another TAD game) in 1990.
+
+ - When "Starting Coin" Dip Switch is set to "x2", you need 2 coins to start
+ a game (but 1 coin to join), then 1 coin to continue.
+ However, it you insert 2 coins, and press START2, you start a 2 players game.
+
+ - Bits 6 and 7 of DSW are told to be unused, but bit 7 is tested when
+ entering the initials (code at 0x00497e, 0x014cf2 and 0x014dc4
+ Note that bit 8 (!) is tested at 0x0049a2, so this has no effect.
+ - Bit 7 of DSW is also "merged" with bit 6 (code at 0x0002f6 and 0x000326).
+
+
+3) 'skysmash'
+
+ - This game only has 2 buttons : bits 6 and 14 of players inputs are NEVER tested !
+
+ - When "Starting Coin" Dip Switch is set to "x2", you need 2 coins to start
+ a game (but 1 coin to join), then 1 coin to continue.
+ However, it you insert 2 coins, and press START2, you start a 2 players game.
+ Also note that when "Starting Coin" Dip Switch is set to "x2", SERVICE1
+ adds 2 credits instead of 1.
+
+ - Bit 6 of DSW was previouly used as a "Cabinet" Dip Switch (OFF = Upright
+ and ON = Cocktail), but it isn't tested outside of the "test mode".
+ Check code from 0x021abe to 0x021afc (and the "rts" instruction at 0x021adc)
+ - Bit 7 of DSW is only tested at 0x02035e and writes a value to 0x0c0100.
+ I don't know what it is supposed to do, but it could be a "Flip Screen"
+ Dip Switch as in 'toki' (same manufacturer and similar hardware).
