Alas, Critic, they're almost all ripoffs of established games
Busy Police = Keystone KapersChallenge - original/unique
Circus = Circus Atari
Dragon Treasure = Dragonfire
Earth Attack = Defender
Farmer Dan = Gopher
Freeway = Freeway (Activision)
Frontline = CombatInca Gold = Pac-Kong, Spider Kong, etc.
Laser Volley = Laser Gates
Ocean City Defender = Atlantis
Pinball = Video Pinball
Radar = Cruise Missile aka Exocet
Scuba Diver = Sea Hunt (Froggo), Bi! Bi!, Skin Diver, etc.
Sea Hawk = Sea Hawk by Froggo
Space Adventure = Flash Gordon
Time Warp = original/unique
Turmoil = Turmoil (20th Century Fox)
So the only two of those games you haven't covered yet are Challenge and some version of Inca Gold. It'd be great to see both of those reviewed! The latter game has a dizzying array of alternate titles
, including Donkey Kong (!!!).
Of course if you want to try the Zellers ROM variants, they're all available in that ROM Hunter set I PM'ed you about a while back. The big trick there is that the "original" versions of games, i.e. the ones believed to be the ones that companies like Zellers ripped off
, are usually marked with a tilde character.
yup and here are the differences from the originals
Busy Police (AKA Keystone Kapers by Activision) - The Activision logo has been erased while the Activision color bars and copyright still remain the same.
Challenge - NTSC version of a suspected Funvision PAL original. Challenge also exists in an ultra-rare NTSC Halley's Comet cart. AFAIK it exists nowhere else in NTSC.
Circus (AKA Circus Atari by Atari) - Hacked to use the joysticks instead of the paddles.
Dragon Treasure (AKA Dragonfire by Imagic) - None
Earth Attack (AKA Defender by Atari) - © 1981 Atari has been erased.
Farmer Dan (AKA Gopher by US Games) - Copyright 1982 U.S.Games has been erased.
Freeway - (Freeway by Activision) Activision logo has been erased.
Frontline (AKA Combat) - None
Inca Gold (AKA Spider Maze) - The Funvision logo has been erased. Spider Maze (K-Tel) NTSC is exactly the same game, but with Funvision logo still intact. Funvision is probably the original company, but this game has been pirated so many times that it's hard to tell.
Laser Volley (AKA Laser Gates by Imagic) - When you die © 1981 Imagic has been replaced with the word "END".
Ocean City Defender (AKA Atlantis by Imagic) - The ufo sprites and some city sprites have been changed. The © 1982 Imagic has been replaced with the Funvision symbol and logo. Might be a few more changes.
Pinball (AKA Video Pinball by Atari) - none
Radar (AKA Cruise Missile, pirated by Froggo) - none
Scuba Diver (Scuba Diver, pirated by Froggo) - none
Sea Hawk (Sea Hawk, pirated by Froggo) - none
Space Adventure (AKA Flash Gordon by 20th Century Fox) - none
Time Warp - NTSC version of a suspected Funvision PAL original. I've seen other NTSC Time Warp roms, but I am unsure of what carts/built in game consoles they belong too. The Zellers version is a good one to pick up. I don't know of another NTSC cart of it.
Turmoil (Turmoil by 20th Century Fox) - The game name "Turmoil" has been erased.
