    Dacholer    (c) 1983 Nichibutsu
    Kick Boy    (c) 1983 Nichibutsu

    Driver by Pierpaolo Prazzoli

    TODO:
      - is the background color pen correct for both games? (Dacholer probably
        just use a different color prom data)

    Mods by Tomasz Slanina (2008.06.12):
      - fixed sound cpu interrupts (mode 2 (two vectors)+ nmi)
      - added sound and music.
      - ay/msm clocks are arbitrary
      - just a guess - upper nibble of byte from port 3 _probably_
        contains sound command (sound cpu writes it to port c)
