Thanks Darius and Hunter!
You can create a custom 240p resolution in windows with any new gpu. Some games I have noticed gets screwed up graphicly even if you set it at it’s native resolution. So this is what I do.
- Start the game.
- Go to setting / video / scaling.
- Let aspect ratio be at custom.
- Turn off integer scale, then on. Or just on.
Now you can see the games native res at width and height.
Set width to x2 and height to x1. Why you ask? Because I have discovered (and this is probably not new to many here) that if you run certain games at it’s native res and with width at x1, graphics, escpecially text, can get messed up. I dont know why. So i always run width at 2 times. Anyway, there is the resolution you should create for that game in nvidia control panel. For instance, every N64 game I have played is 320x240 so I run those games in 640x240 resolution.
I would recommend using an ultra-wide “super” res, like 1920 or 2560 or 3840 by 240/480 and then set the custom width to match. That will eliminate all visible horizontal scaling artifacts.

That is probably easier instead of having one res to every damn console

It does look better with Blargg’s filter enabled, however I see this as a limitation - only handful of emulators implemented this filter. Also what is a point of having grade and Blargg enabled at the same time - both of them used for gamma tinkering I presume ?!

Blargg’s filter does something to the image that grade alone doesn’t do, something to do with blur or scaling or some such.
I started a thread about it, but still haven’t gotten to the bottom of it. We need to figure out what Blargg’s RGB filter is doing, precisely, so it can be replicated via a shader. So far the topic hasn’t generated enough interest, though

Sometime a long time ago I have contacted Blargg as I wanted his RGB version of his filter to be ported to KEGA fusion. He told me -if I remember correctly- that he could provide me the source code or something and that I would have to compile it myself in order to create it. Here is the link to his site if you would like to contact him. I hope this helps!

We have the source already. It’s in each of the core repos that supports it and in the RetroArch video filter tree

Hahahahahaha 
I see you’ve decided to go to the low sharpness side.
It’s still quite sharp where it needs to be. That’s why Blargg’s filters look good, IMO. NES “feels right” with ntsc emulation. I use rgb for everything else.

Excuses excuses, I can see your settings lol
Ye, that edge correction guest added to sharpness settings really altered how the sharpness worked.

Yeah I find that higher sharpness settings can cut things off in an awkward-looking way, especially when using shadow masks. I think higher sharpness looks more natural when using aperture grilles. Kinda makes sense, they were sharper IRL.

Haha no sass intended, just happened to be working on that at the same moment that @guest.r posted 
I think it’s about as realistic as one can get at 1080p, I try to consider the phosphor triad shape and the number of phosphor triads per scanline as seen on a typical slot mask TV.
