Thats a great list you've got so far. All quality games that you'll enjoy.
As far as other games besides those, I think Street Fighter 2: The World Warrior is a great game. The best fighting game on the VC so far. Its 800 points and its a genesis game, so you'll need a GCube or VC controller to play it.
Other personal favorites of mine:
Mario Kart 64(even thought you said that you didnt like the most popular games from each system)
Bomberman 93' for the TurboGrafix16. Thats 5 player, you can use the wiimote, or the GC and VC controllers, plus its only 600 points.
I'll edit if i think of any others.
Hope that helps,
