Depends on what you use to emulate and how much you want to hurt the device.
I usually emulate using RetroArch and it got all the CRT shaders you might want. Unless you get really into it. Look for CRT shaders with words “hylian glow”, geom and royale. There even exist some advanced shaders for high refresh rate monitors that try to emulate CRT beam.
You can also check out Retro Crisis on YouTube to get started.
