Lozano Baides TODO: West Story: - sound (still has IRQ problems) - some bad sprites (2 bad sprite roms, should the actual decoded data match?) Blood Bros (c) 1990 Nihon System [Seibu hardware] ----------- The manual states: At Power On, if you touch the joystick, you will have DIP-SW setting on the screen This works for all sets and the bootleg. Fabtek licensed this game for the U.S. along with other games by Seibu and TAD. Though no Fabtek-licensed set has been dumped yet, and the program code does not appear to test a region byte, the TAD strings displayed on the title screen are both space-justified to the same length as the unused string "U.S. LICENSEE FABTEK, INC." Sky Smasher (c) 1990 Nihon System [Seibu hardware] ----------- Like some other Seibu hardware games, hold P1 right at boot to view DIP descriptions. The manual states: At Power On, if you touch the joystick or SHOOT or MISSILE button, you will have DIP-SW setting on the screen 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 MACHINE_NO_COCKTAIL despite the games being upright) If the word at 0x488 in the maincpu ROM is set to any value other than 1, the attract mode will include the "Winners Don't Use Drugs" screen. The only other change this effects is reducing the first "NIHON SYSTEM INC." on the title screen to the initials NSI. The string "US LICENSEE FABTEC INC" appears twice in the program ROM, but no code that might display it is known to exist. 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) 'bloodbroa' - 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 0x004a46, 0x014bd8 and 0x014cac) 3) 'weststry' - This bootleg has been released by Datsu in 1991. This "company" also bootlegged "Toki" (another TAD game) in 1990, and several Sega titles. - 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). 4) '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). DIP locations verified for Blood Bros. & Sky Smasher via manual & DIP-SW setting screens at power up. **************************************************************************/ #include "emu.h" #include "cpu/m68000/m68000.h" #include "cpu/z80/z80.h" #include "sound/3812intf.h" #include "includes/bloodbro.h" #include "video/seibu_crtc.h" /* Memory Maps */ static ADDRESS_MAP_START( common_map, AS_PROGRAM, 16, bloodbro_state ) AM_RANGE(0x000000, 0x07ffff) AM_ROM AM_RANGE(0x080000, 0x08afff) AM_RAM AM_RANGE(0x08b000, 0x08bfff) AM_RAM AM_SHARE("spriteram") AM_RANGE(0x08c000, 0x08c3ff) AM_RAM_WRITE(bgvideoram_w) AM_SHARE("bgvideoram") AM_RANGE(0x08c400, 0x08cfff) AM_RAM AM_RANGE(0x08d000, 0x08d3ff) AM_RAM_WRITE(fgvideoram_w) AM_SHARE("fgvideoram") AM_RANGE(0x08d400, 0x08d7ff) AM_RAM AM_RANGE(0x08d800, 0x08dfff) AM_RAM_WRITE(txvideoram_w) AM_SHARE("txvideoram") AM_RANGE(0x08e000, 0x08e7ff) AM_RAM AM_RANGE(0x08e800, 0x08f7ff) AM_RAM_DEVWRITE("palette", palette_device, write) AM_SHARE("palette") AM_RANGE(0x08f800, 0x08ffff) AM_RAM AM_RANGE(0x0a0000, 0x0a000d) AM_DEVREADWRITE("seibu_sound", seibu_sound_device, main_word_r, main_word_w) // AM_RANGE(0x0c0000, 0x0c007f) AM_RAM AM_SHARE("scroll") AM_RANGE(0x0c0080, 0x0c0081) AM_WRITENOP // ???
