Alpha One == Major Havoc prototype
Asterock == Asteroids bootleg
Bradley Trainer == Battlezone variation (not really a true game either)
Delta Race == Omega Race clone
Lunar Battle == Gravitar prototype
Meteorites - not on KLOV, not in MAME
QB-3 - only recently added to MAME, little info on KLOV, will add what I can find
Stellar Castle == Star Castle clone
Tempest Tubes == Tempest bootleg
I did the list as an offshoot from one of the topics where the ZVG and the concept of a vector only cab was brought up. With a Space Duel cab you can support a high percentage of the vector games, but it would be next to impossible to support all of them without a frankenpanel or modular controls.
