/*
   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
     - 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
     - ROZ update causes music to stutter
