/* Ken Sei Mogura: Street Fighter II
  aka Street Fighter II Whack-a-mole game */

/*
  this game uses a CPS1 board as the 'Video board'
  the main game is driven by an additional PCB containing a TMPZ84C011 and MB89363B
  moles + hammer are physical non-video parts

  https://www.youtube.com/watch?v=wk71y7OGU-k
  https://www.youtube.com/watch?v=mV00MMyBBXM
  https://www.youtube.com/watch?v=yQpMvRL0FfM

  todo:
  - we have no way of telling the physical order of the moles on the control panel vs. the reads / writes
    so our moles could be in the wrong positions - maybe there are fixed patterns in the video we can use
    to figure it out? * the big mole appears to be worth 2 points so that one we can identify
