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

    Driver for Midway V-Unit games

    driver by Aaron Giles

    Games supported:
        * Cruis'n USA (1994)       [3 sets]
        * Cruis'n World (1996)     [4 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
