I'm selling my Nintendo 64 with two controllers. I've upgraded the controllers to use hall effect sensors rather than the original optical mechanism, so they won't degrade over time. Also including the OEM joysticks in case you want to swap back to those.
It worked flawlessly last time I used it, but that was 5 years ago or so, and I no longer have a display to verify whether it works, so I can't confirm its function now.
