Work in progress. Please add to it. Images needed.

CRT shaders

These replicate Aperture Grille CRTs. These have sharp images and strong scanlines. Shadow-mask CRTs are far more common. However, to replicate that that one would need a very high resolution display (4K or around there). For this reason, shaders replicating Aperture Grille CRts are all that we will see for the time being.

Use integer scaling. This means either using windowed mode (x2,x3,x4) or setting an integer scaling option in the video options. The reason is that non-integer scaled scanlines will result in uneven lines with artifacts.

NTSC filteers

These replicate the cables used to connect the system to the tv. They are created by blargg.
