-general info-------------------------------------------------------------------

 A Pinball Game from Tecmo, the Hardware seems to be somewhere between that used
 for Tecmo's classic game Ninja Gaiden (see gaiden.c) and that used in Comad's
 Gals Pinball (see galspnbl.c) I imagine Comad took the hardware that this uses
 as a basis for writing their game on, adding a couple of features such as the
 pixel layer.

-working notes------------------------------------------------------------------

 68k interrupts
 lev 1 : 0x64 : ffff ffff - invalid
 lev 2 : 0x68 : ffff ffff - invalid
 lev 3 : 0x6c : 0000 1a0a - vblank?
 lev 4 : 0x70 : ffff ffff - invalid
 lev 5 : 0x74 : ffff ffff - invalid
 lev 6 : 0x78 : 0000 1ab2 - writes to 90031
 lev 7 : 0x7c : ffff ffff - invalid

 I can't use tilemap routines because they don't work with tiles having a
 greater height than width, which is the case on this game once its rotated.

TODO : (also check the notes from the galspnbl.c driver)

  - coin insertion is not recognized consistenly.
  - sprite/tile priority is sometimes wrong (see 1st table when ball in bumpers).
  - lots of unknown writes, what are they meant to do
  - verify some of the code which is from the other drivers such as sprite
    drawing as priorities are questionable in places
  - add support for blended sprites.
