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

   Run and Gun / Slam Dunk
   (c) 1993 Konami

   Driver by R. Belmont.

   This hardware uses the 55673 sprite chip like PreGX and System GX, but in a 4 bit
   per pixel layout.  There is also an all-TTL front overlay tilemap and a rotating
   scaling background done with the PSAC2 ('936).

   Status: Front tilemap should be complete, sprites are mostly correct, controls
   should be fine.


   Change Log:

   (AT070703)
   drivers\rungun.c (this file)
     - mem maps, device settings, component communications, I/O's, sound...etc.

   video\rungun.c
     - general clean-up, clipping, alignment

   video\konamiic.c
     - missing sprites and priority

   Known Issues:
     - no dual monitor support is broken
        - games seem to think they're in dual-monitor mode when they're not
        - speed in some sets is incorrect (for dual monitors I'm guessing it should
          output alternate frames to alternate monitors, but due to other bugs it
          just causes the game to run twice as fast as it should?)
        - synchronization and other oddities (rungunu doesn't show attract mode)
        - swapped P12 and P34 controls in 4-player mode team selectet (real puzzler)
        - P3 and P4 coin chutes not working in 4-player mode


     - sprite palettes are not entirely right
