  Dragonball Z
  Banpresto, 1993

  Dragonball Z 2 Super Battle
  (c) 1994 Banpresto

  Driver by David Haywood and R. Belmont

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

  Status: DBZ2 is playable with music and sound and proper controls/dips.

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

  TODO:
	- Gfx priorities (note that it has two 053251)
	- Self Test Fails
	- Some offsets/colours in DBZ1

PCB Layout:
