I'm going to go out on a limb here and say that BATTLE ZONE was made for the Virtual Boy from the get go. The arcade game made you look into a big engulfing scope, just like the Virtual Boy. And it used a very similar technology, so why no Battle Zone?

Well, now there is! As you can see above there are two pictures of the Battle Zone update for the Virtual Boy! Hopefully you will be able to handle all the red!
