NTSC filters
These replicate the cables used to connect the system to the TV. They vary in quality, with the lowest being RF, then composite, then s-video and RGB (scart) being the highest quality. Many emulators have NTSC filters built into them. They can also be separately downloaded in .filter format. They were developed by blargg. Possibly others? More history.
The level of blur in RF and composite cables are needed for dithering to work. S-video, and RGB are too clear to produce dithering.
SNES games make use of the color correction in these cables.
