I've searched the forums here, including the official N64 forum, as well as eBay and Google. But I can't seem to find any kind of joystick for the Nintendo 64. I'm not interested in the standard controller, I want to know if anyone actually made (makes?) a regular joystick for this system.

Don't ask me for what games I want it, as I don't even own an N64. My dog's groomer is actually looking for one and has had no luck.
