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

	Driver for Midway V-Unit games

	driver by Aaron Giles

	Games supported:
		* Cruis'n USA (1994) [3 sets]
		* Cruis'n World (1996) [3 sets]
		* War Gods (1996)
		* Off Road Challenge (1997)

	Known bugs:
		* textures for automatic/manual selection get overwritten in Cruis'n World
		* rendering needs to be looked at a little more closely to fix some holes
		* in Cruis'n World attract mode, right side of sky looks like it has wrapped
		* Off Road Challenge has polygon sorting issues, among other problems
