/***************************************************************************

Excellent System's ES-9209B Hardware

Games supported:

   Grand Cross Pinball
   Power Flipper Pinball Shooting


Made from Raine source


Code
----

Inputs get tested at $4aca2 on


TODO
----

 - Screen flipping support
 - Modernize ES-8712 and hook up to MSM6585 and HCT157
 - Figure out which customs use D80010-D80077 and merge implementation with Aquarium
 - Is SW3 actually used?
 - Power Flipper reference video: https://www.youtube.com/watch?v=zBGjncVsSf4 (seems to have been recorded with 'flipscreen' dipswitch on, because it causes a jumping glitch before the raster effect, same in MAME)

BGMs (controlled by OKI MSM6585 sound chip)
  MSM6585: is an upgraded MSM5205 voice synth IC.
   Improvements:
    More precise internal DA converter
    Built in low-pass filter
    Expanded sampling frequency

Stephh's notes (based on the game M68000 code and some tests) :

  - Reset the game while pressing START1 to enter the "test mode"
