A few years ago I got 3 of those retro-bit n64 controllers (with the ps2 style joystick). They all work fine for Mario Kart 64 and Diddy Kong Racing but none of them work well for Smash Bros.
A few weeks ago I tried getting a couple of the Tomee controllers which had similar problems with the buttons (and the joysticks to a lesser extent). I also tried the Cirka controllers (the ones that actually look like official knockoffs) which were almost entirely poor.
The question i'm having difficulty with is why on earth is the n64 controller so hard to replicate? I haven't really had this problem with 3rd party controllers for more recent systems, or even the 3rd parties from back in the day like the Superpads. Is it because of the smaller market for retro so quality control is not as good? The control stick in particular seems to be particularly tricky.
I'm looking for answers as this has some pretty big implications in terms of those recently kickstarted retro fighters pads. They look awesome and if I could trust that they worked I'd just get 4 of them. But my faith in these companies that I believe have good intentions has been shaken
It may be because the N64 was part of the genesis of analog joysticks, so the tech is just so dated and weird, people are not making N64 joysticks for N64 controllers. Rather, they implement a modern joystick, which in its own right works perfectly fine, but then convert its signal so the N64 can understand it. Both N64 joystick and modern joysticks are highly sensitive, but in different ways.
Or at least that's how I see it.
