Not exactly emulation but thought this would be the most relevant place to talk about the Majora's Mask recompilation, and recompilations of other N64 games thanks to a tool that allows N64 roms to be translated into PC ports.
Been playing the Majora's Mask one and it's great. 60fps, easy to use settings menus, ocarina/mask shortcuts on the d-pad.
Nerrel going into it in more detail on his video:

Its a more involved process with the other games right now but it looks like it won't be long until pretty much every n64 game is playable that way.
Outside of romhacks this is pretty much going to bypass the need for n64 emulation on anything that can run it - Windows and Linux I believe, which means it'll run on Steam Deck too.
