Most emulators have video rendering filters for this kind of concern; they have for a long time. SNES9X from more than a decade ago already implemented.
This is running Dolphin which can render 3D graphics at higher resolution. Then you can apply high res gesture packs. It ends up turning the game into a next gen game. That only really works with 3D games. snes and other 8-16 bit consoles still benefit from a CRT.
which doesnt apply to all games on said device. an example is that viewers vastly prefer the cleaner footage that comes off of streams generated by dolphin using slippi over wathing the native crt footage. unlike a single individual (yourself) generalizong the preference, this is a real life scenario with thousands of viewers on the same content, many of which is also very used to the crt as many are also players.
coming from a person who lugged a crt just for melee in college for years.
