/* Final Crash */

/*

Final Crash is a bootleg of Final Fight

Final Fight is by Capcom and runs on CPS1 hardawre
The bootleg was manufactured by Playmark of Italy

this driver depends heavily on cps1.c, but has been
kept apart in an attempt to keep cps1.c clutter free

todo:
Add Sound (very different to CPS1)
