They weren't Arcade only at the time. Pikachu & Ness however were SNES & GB only at the time.
Okay so, Pikachu was a Game Boy rep once and literally has nothing to do with it's original Game Boy appearance these days or in Smash, in fact it's design has been slightly changed as well.
So the Game Boy is obviously well represented.
But Mario and Donkey Kong don't help rep the Arcade because they had games on other systems during the existence of Smash games, despite them doing things inspired or actually done by them in the arcade games.
Obviously, the arcade is being very neglected.
That's probably the dumbest argument I've heard you say in a while. "Gameboy and the SNES were represented in one game! So there is no need for any retro characters from those systems even those characters no long represent the system!" while you go ahead and say, "The Arcade needs a character! The existing ones aren't arcade only and therefor aren't arcade characters!"
Come on, you can't be serious.
I also edited my post after you quoted my post because you didn't respond by that time, so here it is again.
EDIT: The arcade has been referenced in each game through the Hammer, so that's another thing. I mean you can represent things through stages, items, music, trophies, and even stickers. Sure you're saying that the arcade needs representation, but's had a fair share of it through the years by other means. It doesn't need a character when the memorable ones are already playable (and with Pac-Man possibly making it in, that just helps represent it more right?).
So that's something to consider too. Representation isn't limited to just the characters, but to all content in Smash. I'm sure you're aware of this, but you gotta keep that in mind too.

In Unrelated news, Mighty No. 9 funding is done, we actually reached $4 Million to get Online Battle Race Mode, HURRAY!
Call F made it the next round~
Can't say I'm surprised though. But I do have to admit that I do kinda like Call H a bit (My second choice was A).

Snake or Layton?
Snake.
Going to be hard pressed to find a 3rd Party choice that I would want Snake bumped out for.
Agumon or Leomon.
