Zaxxon
Pooyan (loved this game!)
Klendathu (although, I thought it was under another name, or maybe it was a combo-cartridge with a chopper game where you shoot out fires. Was Klendathu the game where it would say "Nyah, nyah, nyah na! We gotttttt youuuuuuuuu!!!!!"?)
Dallas Quest (never could get past that stampede when the thunderstorm came...)
One on One (Didn't care for it much other than trying to make the glass break).
Outhouse (Don't know, but this one was funny at the time)
Sea Dragon
The Factory (my friend had this game for the Apple ][e)
Dungeons of Daggeroth (my dad liked this one)
Lunar Rover! (couldn't get past this one double jump in the later stages)
Buzzard Bait (I had the one where the pterodactyl made a sound)
War Kings (another favorite. Best round was when a cannonball bounced around my "castle" a dozen times, scraping the king in the process. I think I eventually won that game.)
Ninja Warrior (I think there was a double jump with a bonfire in the middle that I could never get past. Obviously, my hand-eye coordination wasn't developed yet between 5-8). Granted, the graphics are a bit bigger than what I remember, unless I had another version.
Crystle Castles
Color Baseball (this game had a bug where you could touch the pitcher's mound and the runner would be out)
Dancing Devil(/Demon) (never quite got the purpose of that game. I guess it was the first "Dance Dance Revolution" game for its' time)
Fire Copter
