  Dragonball Z                  (c) 1993 Banpresto
  Dragonball Z 2 - Super Battle (c) 1994 Banpresto

  Driver by David Haywood, R. Belmont and Pierpaolo Prazzoli

  MC68000 + Konami Xexex-era video hardware and system controller ICs
  Z80 + YM2151 + OKIM6295 for sound

  Note: game has an extremely complete test mode, it's beautiful for emulation.
        flip the DIP and check it out!

  TODO:
    - Self Test Fails
    - Banpresto logo in DBZ has bad colors after 1 run of the attract mode because
      it's associated to the wrong logical tilemap and the same happens in DBZ2
      test mode. It should be a bug in K056832 emulation.
