Super Dodgeball / Nekketsu Koukou Dodgeball Bu

briver by Paul Hampson and Nicola Salmoria

TODO:
- sprite lag (the real game has quite a bit of lag too)
- double-tap tolerance (find a way to dump + emulate MCU?)

Notes:
- there's probably a 63701 on the board, used for protection. It is checked
  on startup and then just used to read the input ports. It doesn't return
  the ports verbatim, it adds further processing, setting flags when the
  player double-taps in one direction to run.(updated to edge-triggering)

- video timing is probably similar to Double Dragon and other Technos games
  of that era.  The rowscroll of the title bar is done with raster IRQs, I've
  removed the 'scroll value buffer' hack that the driver was using before and
  used partial updates instead. (DH, 29 Sept 07)
