Re: ZVG special pricing

There are 2 different colorization options to MAME developers, Overlay and
Background, where as in a Game like Asteroids Deluxe, you don't want that
color transfering to the Vectors, and Battle Zone to change the color of the
vectors..... Mame will pass the vectors as the "Colorized" vectors for
BattleZone already... works like this for LaserMAME at least...

Star Castle is at least one of the Exceptions... Whomever wrote the Mame
Emulation of Star Castle, they used the Background option of MAME to colorize
this in Raster, and it won't transfer to colorizing the Vectors currently...
Should be a quick fix probably a single line in the Header, I just havn't found
it yet
