    Coors Light Bowling/Bowl-O-Rama hardware

    driver by Zsolt Vasvari

    Games supported:
        * Capcom/Coors Light Bowling
        * Bowlorama

    Known issues:
        * none

****************************************************************************

    CPU Board:

    0000-3fff     3 Graphics ROMS mapped in using 0x4800 (Coors Light Bowling only)
    0000-001f       Turbo board area (Bowl-O-Rama only) See Below.
    4000          Display row selected
    4800          Graphics ROM select
    5000-57ff     Battery backed up RAM (Saves machine state after shut off)
               Enter setup menu by holding down the F2 key on the
               high score screen
    5800-5fff       TMS34061 area

               First 0x20 bytes of each row provide a 16 color palette for this
               row. 2 bytes per color: 0000RRRR GGGGBBBB.

               Remaining 0xe0 bytes contain 2 pixels each for a total of
               448 pixels, but only 360 seem to be displayed.
               (Each row appears vertically because the monitor is rotated)

    6000          Sound command
    6800            Trackball Reset. Double duties as a watchdog.
    7000          Input port 1    Bit 0-3 Trackball Vertical Position
                                Bit 4   Player 2 Hook Left
                                Bit 5   Player 2 Hook Right
                                Bit 6   Upright/Cocktail DIP Switch
                               Bit 7   Coin 2
    7800          Input port 2    Bit 0-3 Trackball Horizontal Positon
                               Bit 4   Player 1 Hook Left
                               Bit 5   Player 1 Hook Right
                               Bit 6   Start
                               Bit 7   Coin 1
    8000-ffff       ROM


    Sound Board:

    0000-07ff       RAM
    1000-1001       YM2203
                Port A D7 Read  is ticket sensor
                Port B D7 Write is ticket dispenser enable
                Port B D6 looks like a diagnostics LED to indicate that
                          the PCB is operating. It's pulsated by the
                          sound CPU. It is kind of pointless to emulate it.
    2000            Not hooked up according to the schematics
    6000            DAC write
    7000            Sound command read (0x34 is used to dispense a ticket)
    8000-ffff       ROM

                This portion: Mike Appolo with the help of Andrew Pines.
                Andrew was one of the game designers for Capcom Bowling,
                Coors Light Bowling, Strata Bowling, and Bowl-O-Rama.

                This game was an upgrade for Capcom Bowling and included a
                "Turbo PCB" that had a GAL address decoder / data mask

    Memory Map for turbo board (where GR0 is on Capcom Bowling PCBs:
