I was working on something else and randomly I came with this kind of visual that I think is good for low res systems like handhelds.
It’s called Retro-Tiles. It turns pixels into some kind of tile with a bump illusion. I think it’s much bette than the old Retro-v2 shader.
It’s already in slang shader repo, so you just need to use shader update online inside RA to get it.
And you can fix colors by using the core options or other shaders specifically for this purpose.
Here some screenshots. It gives a nice effect in sprites:
