/*

 Lucky Girl (newer 1991 version on different hardware?)
  -- there is an early 'Lucky Girl' which appears to be running on Nichibutsu like hardware.

 The program rom extracted from the Z180 also refers to this as Lucky 74..

 TODO:
 - inputs / port mapping
 - sound (what's the sound chip?)
 - reel scroll / reel enable / reel colours
 - are the colours correct even on the text layer? they look odd in places, and there are unused bits
 - dunno where / how is the service mode bit is connected (I've accessed it once, but dunno how I've did it)
 - graphics in 7smash are quite off (encrypted ROM?)

     LUCKY GIRL DREW'S

 Text underneath label

 WE 300B 1H2

 Looks like Hitachi part markings to me.

 Other notes

 Has some optocouplers, high voltage drivers, and what looks like additional
 I/O conenctors.

 Reset switch cuts power supply going to Video/Work RAM.

  C0-C3 seems to be a 4-bytes port device (maybe sound), where is written --> data, control (or channel), unknown, volume.
  If in fact it's a sound device, the last parameter (volume) is decreasing once the sound event was triggered.
  Seems to be more than one, and these devices seems mirrored along the rest of memory.
