I personally recommend Vencord, works great for me, has an installer on their github and comes preloaded with some plugins BetterDiscord simply lacks.

Also yes I am aware that "Retroarch" is the frontend and "Libretro" is the library, Retroarch is just longer and wouldn't fit as well on the image. I'm also aware some of these have libretro ports, just giving some emulators that I think are really nice standalone. Hop in the comments and ask for a console and I might have a recommendation.
