Do you mean is it possible to do so or are you allowed to? The question is a bit ambiguous.

sorry,i want to use input display on my stream I know how to use input display on console but I dont know it for emu ;;;;;;;;;;;;

on obs, make a BrowserSource and enter this url : https://gamepadviewer.com/ it should make your inputs from your controller visible. if you play keyboard, i don't know how to.

or just use a program called NintendoSpy. I believe most people use this, if they have a display at all.

editing this six years later just in case somebody finds it; you're looking for Project64spy https://www.mediafire.com/file/d1ez10rsg1yycto/Project64Spy.zip
