Interesting. I just checked out Orbitron and I get the impression it's a graphics hack of Victory, not the other way around, because notice on the radar screen it shows what looks like three ships rather than the one big spaceship you're controlling. Also in attract mode right before the title screen it seems to show the same logo for Comsoft that's printed on that black security module. If it is a hack of Victory I wonder if there's anything that can be learned from the code?
