Some Dynax games using the first version of their blitter

driver by Nicola Salmoria, blitter support based on work by Luca Elia

CPU:    Z80-A
Sound:  YM2203C
        M5205
OSC:    20.0000MHz
Video:  HD46505SP

---------------------------------------
Year + Game                 Board
---------------------------------------
87 Hana Yayoi               D0208298L1
87 Hana Fubuki              D0602048
87 Untouchable              D0806298
---------------------------------------

Notes:
- In service mode, press "analyzer" (0) and "test" (F2) to see a gfx test

- hnfubuki doesn't have a service mode dip, press "analyzer" instead

- untoucha doesn't have it either; press "test" during boot for one kind
  of service menu, "analyzer" at any other time for another menu (including
  dip switch settings)
  Note: screen asking to press test during boot does not show if machine contains credits.

TODO:
- dips/inputs for some games
- untoucha: player high scores are lost when resetting

15-July 2016 - DIPs added to untoucha [theguru]
