Relevant knowledge/discussion which I have drawn upon

https://forums.overclockers.com.au/threads/n64-thumbstick-repair-or-replacement-whats-best.1170136/ (the problem is more complicated than just the gearing. By design the base of the joystick is in constant contact with the spherical bowl it sits in. Unsurprisingly over time plastic joystick rubbing on a plastic bowl eventually creates wear on both the bottom of the joystick and the bowl. I have seemed ppl use a hard curing putty to repair the surface of the bowl by shaping it with a ball bearing and letting it cure but there is little you can do with the bottom of the joystick.)

(like many of you said, the replacements are for 3rd party controllers. I wound up with a couple of those sticks myself. the problem with the 64 is that used a light-shutter wheel design to measure the position of the stick, instead of the more accurate potentiometer that all modern sticks use. another problem with most replacement sticks is that they are mechanically designed exactly the same, so they too will wear out from heavy use. if not wear out faster due to cheaper plastics.

a potentiometer (commonly referred to as a "pot") is a variable resistor. turn it one way, resistance goes up, turn it the other and it goes down. it is the exact same part as a volume knob, only they use two to measure both an x and y axis.

regretfully, the technology is completely incompatible. other replacement sticks you buy on eBay with the 6-wire plug are ALSO designed using pots, however, these come with a small circuit board inside that converts modern pot signals into the older shutter wheel signals. regretfully, cheap products were used, and the modern replacements suffer from some pretty bad input lag/skipping. an example of this skipping can be seen on this video.

that video is also showing the solution. guys way smarter than me programmed an attiny microcontroller themselves that managed to convert the light wheel to a pot signal.

to replace my stick, i bought one of the replacements sticks off eBay, but one of the more modern, GameCube style sticks. these are designed more like modern sticks and will not have the mechanical wear that even normal replacement sticks will suffer from. i then took out the stick’s converter board and soldered in one of the attiny chips i had to program

.

the result is a controller as good as the original, and a stick on par with a hori mini. additionally, the guys that made the program made it so that if you add an extra wire, you can hold down "B" when you turn the 64 on and get an extra 5% sensitivity.

the USB programmer is only about $15, and chips are $2-3 depending on where you buy them. only a small purchase, but for a stick that will last far longer than an original, and work like it should, there’s no better solution.)
