This image is a better example

It's a hot take, but I agree with you.

Actually, I try to find a noise overlay that emotionally simulates the nostalgia effect, minimizes the looks-like-shit effect, but then also makes sure to impart the minimum amount of dither needed to technically have it look it's best.

Less is more, and even back in the day, a lot of these games on crappy CRTs looked like absolute trash. A lot of them were bright, colorful, and actually good, but a lot of them just looked like smeary poopoo.

If I can just squint my eyes and it looks better than your filter, you're doing it wrong. I think it takes a high nit display, vsync, with the right array of colors to hit the crt emulation just right.

Just go get an old tv at this point, damn. You'll get the buttons, the sound of it turning on, the high pitched whistle of it just being on, the smell of the burning dust, the ozone or whatever smell too, the brightness, the curve, the colors, the emotional risk of hitting the wrong channel and blasting yourself with full volume white noise and having to panic look for the volume buttons or the remote.... You can even use the in-tv speakers to output sound! Tv speakers were actually decent before flat screens.

Am I selling us all on this idea, yet? ;P

Agreed. Blowing up the image to a size that you'd never see in actual gameplay makes it look worse than it actually is.
