I'm about 95% sure they are working. I do have the wires and stuff to test them out. They are at my old house across the street, so I'll get around to testing them in the near future.
I have Models 1 2 and 3 and maybe a 2nd 2 (I at least have 3, not positive on the 4th), can't remember the conditions, and I also have 2 3rd party controllers.
From your list I'm interested in Super Smash Bros Melee and Mario Kart Double Dash. I can provide more information if you're interested.
