Good point, yes, I think you’re double correcting with those consoles when you select an NTSC palette- the palette should already be “corrected,” right? Any palette based on the final displayed image on a CRT doesn’t need to be corrected again…
Turbografx 16 is interesting, it did its own internal correction with a LUT to convert RGB to composite video colors before sending the signal to the TV, so the colors stay fairly consistent when switching from RGB and composite.
Nice! What’s that game?
Yeah the design is really cool. It’s a boss from NES game “Isolated Warrior”.

Hey there!
This week’s tweak got me playing some GameBoy Color titles. I’m a sucker for the retroachievement event and this month’s Zelda Oracle of Season is prescribed, so I’ll play that, to praise and please goddess Cheevos.
The shader chain comprise a LCD time response motion blur for transparency sprites based on blinking (I found it looked better to me than the built in motion blur in some cores when using the next shaders on top), JINC2 and ScaleFX for upscaling, GBC color correction and then CRT-Guest-Advanced-NTSC. Thanks you guys so much for all that. Here are some pics in 1080p and a download link if you want to test that, you can set CRT mask size and zoom parameters to your liking and resolution within the shader params ofc.

Hello my old friends and all the “new” people that share the love for CRT simulations. I finally got myself a new computer, and can run all the shaders properly at big resolutions. Was really looking forward to this. By courtesy of guest’s insane shader, enter Pulstar 
To my eyes, it just doesn’t get better than this.
Hey there!
Played some NES games this week. Mesen core with composite by FirebrandX palette, and a preset mixing JINC2, ScaleFX, NTSC adaptive and NewPixie on top. You can get the preset for 1080p here if you want a go at it :

Here are more screenshots demonstrating the WIP effort on the Scanline Classic shader. https://forums.libretro.com/t/the-scanline-classic-shader/41497/13?u=anikom15
I attempted to mimic the S-Video output from the Famicom Titler. The desaturation of colors is due to the belief that the titler cuts the chroma signal by 50%, as described here: https://www.nesdev.org/wiki/X0858CE
The result appears to be somewhat of an overcorrection. I am comparing it to what a composite NES might look like using the WIP composite mode of my shader and the ‘feedback filter’. Note that the screenshots look more filthy than what it looks like while running because the fields blur together and reduce the strength of the rainbow colors.
When I started this “journey”, I had a goal in mind. I just wasn’t sure what it looked like. It slowly revealed itself throughout the years. Thank you all :_)
Ridiculously wide bloom, strong halation and vignette, and screen brightness uniformity on lowest level:
Hi, could you share your setting?
Yes of course. I made this using reshade and standalone MAME because it’s faster for me to run experiments and stack shaders with its gui. I will most definitely port it to retroarch in the near future and post the results here if someone is interested.

What you actually get on a composite more or less, dithering blended while still sharp

Hey there,
Having a blast this week playing MGS on Swanstation, with enhancements like 4x resolution for 3D, adaptive 2D smoothing, xBR textures and PGXP. I still kept dithering and didnt use the widescreen hack, but eventually set 1:1 DAR aspect ratio as I thought it was looking good like that here. And CRT-Guest-HD to postprocess it all. Thanks again for all those great tools!
I think I begin to understand why the guy calls himself Solid Snake. XD
Yeah upscaling makes those PS1 games look like some PC games or the era or some early PS2.
Yeah PGXP is magic. Thanks to that I’ve also managed to play a bit in stereo 3D with the vr headset using this mod on duckstation. I dont want to remove the dithering tho, I like it grainy and a bit nostalgic.
I hope we get something similar for Saturn in the future.
Amiga Gods on a typical RGB shader and crt-consumer-1w-ntsc-XL. Composite will blend all dithering on an A520 modulator (tested on real A500+). This is true PAL composite modulate/demodulate and apply common luma/chroma bandwidth, no any tricks to achieve the effect (like dithering check and merge shader).
Some extra shots
I guess this is just the limited bandwidth at play right?
Also, where there those “dotted color artifacts” from the A520 PAL modulator? I think I only used it via RF.
