I am a big fan of Scanlines, as they provide a smart way to approximate the visual experience on an LCD to what an old CRT used to be. It helps to smooth out the edges and make the games look more "natural" for me. I understand this is a highly debated and personal topic, but still...
Having recently configured a RetroPi in a tabletop arcade machine, I have dabbled with Shaders, and discovered that they can even do a better job at simulating old CRT's than just scanlines.
So my question is, would it be possible to have CRT like shaders implemented in the MiSTer, or is this a feature that cannot be implemented without an operating system like Windows or Linux?
