This is just a curiosity. I wanted to see if anyone here might be able to explain it though.
When I run Asteroids Deluxe (any revision) through the Mame exe directly, the vector graphics have a bluish tint (compared to the original Asteroids' white vectors). But when I launch Asteroids Deluxe in Hyperspin or Hyperlaunch, it looks white, like the original.
It's not really important, but I was just wondering.
