Hello, I'm sorry if this was already requested, I've searched a lot for it but found nothing.
It would be awesome to have a few video CRT/DOT filters added to PICO-8 console. It's something I experiment in Fake-08 and it really changes the vibe of the game, it's like adding texture/details in bland colors. It could even be something games could activate/deactivate automatically. Here a few examples with dot, scanlines, geom crt and off:
Dots (my favorite)
GEOM CRT
I personally think this kind of filter works particularly well with low pixel density content, like PICO-8. What do you think?
