If one is bored, and just looking to make a new arcade stick for the hell of it, or maybe your absolute favorite game is Killer Instinct or one of the other 5 arcade friendly N64 titles, then why not, but generally speaking... The N64 is the worst choice for an arcade controls, as far as consoles go anyway.
So the U360 did not work well for you with Project64 or a console, or is your argument all theoretical?
Well a U360 isn't going to do crap for you on a console, so no not theoretical.
As for its usefulness as an analog control...
Not really my point. The N64 does not have a great line-up of titles that are arcade control friendly.
The only reason I use arcade controls for any game is because I find them to be better suited for the game. If a gamepad or other control style is better suited, then I won't be using an arcade stick.
I can play Forza on the Xbox with an arcade stick. Just because I
can, surely doesn't mean I should.
I never said there were no games on the N64 that would benefit from or be decent with arcade controls. My basic point was just that out of pretty much every other console ever made. It has the least amount of games that would.
The N64 did not have a very large library of games to begin with. Whittle that down to just the ones that would be good with an arcade stick and you have a pretty tiny selection.
