Why not simply turn the interlacing off and increase the threshold?
I did, just wanted to point it out as a possible side effect of changing the default from 4 to 5 compared to the older pack. But beyond that, the colors being vastly different is noteworthy I feel.
So the name of the game for today’s sample pack is contrast. I’ve been wanting to try tweaking some of that in for a while to try and clean up some of those “shaded” areas but wasn’t sure how to balance it with the brightness but I think I may have found some middle ground.
Some before and after shots:
I’ve also included two 1080p only uborder presets:
I’m honestly not sure if including these are worth the hassle but let’s see what some of you think. Before using them go to settings/video/scaling/aspect ratio and set it to “full” to get the whole intended image. There’s these weird horizontal thick lines that appear every few lines going down the image that I can’t seem to get rid of, not even interger scaling fixes it.

But anyway you guys know the drill unzip copy and paste to use them. Don’t use interger scaling, aspect ratio should be 4:3.
I notice that flicker as well, I assume it’s the way guest.r intended for that particular version of Interlacing to react, I also notice if the content isn’t getting full fps the flickering becomes even more crazy. Number 4 was my favorite simply because it kept the screen still no matter the content but it blew the brightness out of proportion, not even I like that much brightness lol.
Out of all choices though 5 is the best looking one to me as it keeps the colors looking the same as it looks on non interlaced content. And wow haven’t seen how my old pack looks in months, things definitely look different now.
Edit: Did a small change, version 2 now up.
Nice, images gained a lot of depth.
Thanks man, I think I spent about 2 days strictly playing with just contrast. As soon as I enabled it the image got dark instantly so my first obstacle was to get that brightness back but still keep the effects that contrast gives and the results definitely show. That shmup image with the reddish sky and ground shows off the effects the best I think.
Tweaking shader settings is probably the most artistic thing I do these days, I treat the guest.r shader like a painting where I just try out little things here and there, like a Bob Ross painting episode lol.
You may have to repost your image on another site or something, it doesn’t show here and clicking it brings me to a non working link
I suppose you could also add scanlines to interlaced content with the “Internal Resolution downsample divider” setting at 1.00 if that could help as an alternative and your game should more or less look like this:
That’s weird that it doesn’t show up. I reuplodaed it I’ll try that downsample divider later.

It’s showing now. Also I swapped in a “version 2” download up there, made some small changes.
Hi! I’m not sure if this is the right place or if you’re still looking for it, but I’ve made reshader accept any retroarch shader with this. It’s worked well for the limited subset of shaders I personally use. I use it all the time with Sonic Origins.
Since you were asking about it, I thought I’d share.
Are you deadass rn?
What a marvelous piece of software! This has the potential of solving most if not all of my issues with non-RA shader implementations. I haven’t had the time to test it out yet, but I’m looking forward to fiddling around with it. Thanks for sharing!
Hi love the shaders but I am having an issue. When it goes to a black screen like loading or transitioning I get these white bars flash across the screen. I have included a recording of the issue. https://www.youtube.com/watch?v=WTFWC0Jxj3Q
How can I get these to not show up? thanks
I’ve seen this before, it is part of guest’s shader, it is related to “raster bloom” . Try checking for something like that.
Hey there and welcome to the forum. That bar “flash” is the “resolution switch” shader that I added in. That can be disabled easily with the very first setting at the top where it says “resolution switch glitch enable” in the parameters settings.
Thanks for the reply, got it sorted now, loving the shaders
Hello guys, how are you? First time here. I’d like some help to use Sonkun’s shaders pack. The shader is applied, but it does not seem to apply any video signal filter (I tried all of them) and the colors are modified (blueish). I tried normal, warm and cool, and all give me the same result. Does anybody know why this happens? (Sorry, as a new user, I can only update 1 image) Thanks in advance.
Sonkun’s shader (slot mask - 1080p - curved screen - u - composite - normal)
That might be the issue.
oh and recommend trying the new release out a few messages up.New sonkun crt guest advanced hd presets thread
those need these guest.r shaders to work right.
New CRT shader from Guest + CRT Guest Advanced updates
I forgot to mention in my last message, but I’ve already downloaded the latest crt guest advanced update. Even with it, the colors are wrong. In the mega man x2 image I posted last time, the sky should be purple-like, but it is more of a blue tone. Although, I liked the color of the orange door, good saturation. I don’t know if someone here already had this bug. In the mean time, I’m trying Cyberlab Mega Bezel and Retro Crisis shaders.
This is quite trivial, there are many colorspace options in regular @sonkun shader pack releases and most of them shift hues acordingly:
Maybe you should try a “u-normal” one instead of “cool” or “j” etc.
