"Cathodemer is a realtime video production instrument with a CRT display simulator. It features analog-style RGB signal oscillation synthesis, input source mixing and manipulation, recursive color shape synthesis, sprite animation engine and various classic video effects."
Also possibly of interest is CLK aka Clock Signal, an emulator that outputs a composite "signal" instead of pixels:
> Consider an ordinary, unmodified Commodore Vic-20. Its only video output is composite. Therefore the emulated machine's only video output is composite. In order to display the video output, your GPU must decode composite video. Therefore composite video artefacts are present and correct not because of a post hoc filter but because the real signal is really being processed.
This is fun and all, but I'm not sure why one would go to the effort to simulate so much of the CRT experience, but not force the window to be the right aspect ratio?
Maldita Castilla sports a very sharp, almost Trinitron-like appearance. The emulated display mask appears to have horizontal slits and is layed out like brickwork (see screenshots near the middle of the page, you'll have to zoom in a little): https://locomalito.com/maldita_castilla.php
Does anyone know which type of CRTs had this look?
It would need some blurring and low res pixelation to be convincing. Also, double images could be implemented to emulate signal reflections on obstacles.
Maybe it's the fact that it isn't really a tube screen, it's in fact a simulation of one through a modern screen. But thanks for such a constructive comment.

Here's the demo: https://www.youtube.com/watch?v=bcez5pcp55w
The RF artifacts completely overwhelm the NTSC artifacts. It looks like a fairly weak RF signal plus other RF noise/harmonics in band.
Did someone touch the VCR again!?!?
