Smoothing shaders for Snes/genesis games?

[dirthurts]

This is probably sacrilege for many, but are there any pixel smoothing shaders for these emulators?
The reason I'm asking, is I have some eye sensitivity issues and jagged edges tend to give me migraines. My brain just isn't good at auto correcting the pixel art and turning it into images, as much as I love it.

I've been searching, but I'm having no luck. I would like something that produces an image something like this:

Is this possible?

@dirthurts that example is closer to remastering than smoothing/shading.

But anyways see here:

Thanks for the reply.

I found the bi-linear filtering option, but it didn't do what I was hoping for.
I've also not been able to identify/find definitions of what these various shaders do...
Is there a list somewhere? The names are...less than descriptive.

@dirthurts did you try setting

video_smooth = true

In the retroarch.cfg for the system you are trying to play?

[dirthurts]

@edmaul69 Indeed it is.

@dirthurts if you have video smooth on you wont see a single sharp pixel. So if you still have sharp pixels there is something wrong

There is a shader preview repository with examples of how many shaders upscale a test image here. It doesn't include crt-pi but herb's link has examples of what that can do.

Note that many of those shaders will not run well or even at all on the Pi. In particular, the sort of algorithms used to upscale images in the way you want use techniques that are poorly suited to the Pi's GPU (i.e. they run very slowly).

Thanks davj. This is exactly what I needed. I'm checking it out now and it seems very helpful. Even if not all of them will run properly.
