Shaders for 480i/p aren’t much popular, but they still can provide improvements. Here’s a quick sample:

Those Marios look awesome…
I’ve played a few EGA titles lately, trying to get those 16 colors moirés patterns smoothed out with Guest-advanced and trying to get the fuschia closer to what skin look like. Only got a CGA 4 colors back in my youth so I rediscover games, but with my idealized version of EGA/Composite. Here’s a preset for 4K. The image I uploaded here is larger in size than the game I played really… And the whole video playthrough of Larry 2 (270Ko) was 17Go. XD https://www.youtube.com/watch?v=SecuQpcFOb4

@mas The screenshot collection looks great!
When posting Sony Megatron Color Video Monitor screenshot it might be a good idea to include some viewing tips, for example, brighten screen or zoom in until it looks good for users who might not have calibrated displays or they might just see them and think too dark and move on.
These look like they’re from my Megatron NX preset pack, am I right? Which presets if you don’t mind me asking?
I will reupload them, when I get home today.
I think, it is a PCE Bad Composite preset with some little changes.

Still tweaking Presets-ng/Monitor-Screen_Hmask-Screen_SlotMask_Taller_Brighter.slangp
The intent is to preserve as much slotmask as possible at higher brightness:

What are the minimum requirements for this preset to look as intended? Would a standard 1080p screen be sufficient?
Yes definitely; 1080p is my target since that’s what I use 99.9% of the times.
Edit:
I tested it deeper, and it seems to be a lucky one with regard to moire.…

After a few weeks with EGA games, I went back to SVGA territory.
I think scaling 480p to 1080p is greatly improved by your shaders. They are amazing tools really, thank you so much! For Warcraft 2 in example here with a preset for CRT-Guest-advanced, I would say it looks even better than the remaster.
The goal was to even out the upscaling and smoothen the uneven chekerboard of the dithered fog of war and various shadows. Also get some color correction and very thin scanline and mask for texture.
Here are the raw pixels :
Here it is with the shader :
You can zoom in on this section for the fine details. There’s still a barely noticeable moiré effect that will completely disappear with integer scaling at 1440p or 4K, but 1080p is looking good IMO.
I also played through the cancelled win98 Warcraft Adventures point and click with the same shader, you can watch it in motion here :

@RetroGames4K, your shots are always an inspiration and a challenge 
Also:
Screw the mask! What if we could just paint it regardless of any screen alignment rule, let’s just draw it and see what happen. curve everything!
Results expectedly look like s**** if you look too near, but surprisingly they give a nice effect from a proper distance.
…of course it happens that there is moire everywhere, just like it happen in photos, so here is a less curved version with some mitigations to the mask; also no green casting and properly more saturated:
-EDIT- Maybe this is ok too, letting just the “rgb” mask to bleed more:
