Stupid Battlezone Question

Hi all,

   Well, I've decided to give, um, "Stupid" Color Battlezone a whirl since I
am out of 15" BW tubes for my newly aquired mini. I have some 15" tubes
from some old CGA monitors I plan on playing around with. A friend of mine
said that they should work....we shall see...

   Forgive my ignorance as I am not familiar with the hardware, but are
there signals on the BZ board that would let me know if a bad guy is being
drawn (i.e. tank, missile, saucer)?

   The red portion of the screen should be straightforward seeing that I can
simply wire up a comparator on the Y axis (i.e. if Y voltage > some
threshold, then drive red, else drive green).

   It'd be great to make everything "bad" related blue or cyan or
something...just for something different! Is this possible, or do I need
better medication? If not, looks like it'll be native green and red
Battlezone only until I can find a 15" BW chassis.

   Sorry about this post if it is lame, but the "true color" Star Castle
post got me thinking...

Ed

Mark Perreira did a great job of all of these things and I believe they have
been incorporated into the newest versions of DOS MAME.

In the MAME.CFG file add:

zvg_artwork = yes // to turn on art work (walls for Armor Attack &
Warrior)
zvg_overlay = yes // to turn on overlays (colorize the B&W games)
zvg_menu = yes // keeps vm_menu.exe from crashing between games
