It could be the ‘completed ver. 2.0’, minus bugs. ofc. Feedback is welcome, as always.
Just wanted to drop in. I managed to update to the latest version (27.12.2020-r2.1), replacing the stock pass with Grade and copying over the parameters like you had suggested, works like a charm! Also managed to tweak my settings a bit with the new Smart Edge implementation, and got something that looks quite good imo. At 1440p Mask 1 looks very nice!
Here are some screenshots. The PS1 screenshots are with default settings except no dithering.

New Release Version (29.12.2020-r1):
I’m finalizing the shader, mainly polishing new changes and cleaning some old issues. Performance and a reasonable implementation are a mighty priority and adding some in general complying effects gets increasingly complicated, so i guess this iteration of the shader is finished (minus possible bugs or a stroke-of-revelation improvement). I’m also very pleased the shader get’s along with other people’s excellent work. The shader still contains two, maybe three usable, but possible placeholder effects i won’t name. 
Happy shading!

Can you recreate and post this old preset of yours for the new GDV2 shader (not for HiRes if possible) :
Hey there!
I guess it’s more appropriate to give a general working procedure to migrate older presets, since it’s quite simple.
In this special case you should also change two parameter values:
New Release Version (31.12.2020-r1.2):
Notable changes:
I found some inspiration to greatly improve the LUT part of the shader composition. The LUT’s are still the same, one is added (credits to Torridgristle), but the patching is much more advanced than before. Using / replacing new LUT’s is much simpler now, even if they have flaws. Artifacts usually happen with darker colors and now, contrary to before, a shift is used to always use LUT colors instead of replacing them with original input colors. If used with very non-offensive brightness correction, the LUT effects are even better looking. Ofc. the corrections can be disabled. Also new is the parameter to chose between 32 and 64 LUT sizes. Size of 16 is not supported because of the worse quality and inappropriate parameter steps.
I also included some interlacing modes for better variety in the high-res repertoire.
Edit: Lut patching improved.

Nice job. All the artifacting with any of the luts is gone for me. Interlacing also looks very nice on Dreamcast.
Nice to hear that. 
I also managed to improve the fidelity of the ‘lut patching’ effect regarding contrast and saturation. When i compared the versions notable differences were observable, but it’s more refined now, patching only where needed.
Do you intend to update the README file?
I am very happy with these updates that you are doing. Your shader is very complete.
Could you create a preset to mimic a VGA monitor? I use two shaders for this, but I would prefer to use only yours.
Thanks!
This is great! I’m going to put the torridgristle’s LUT back in the mega bezel, Although it might wait until I upgrade it to the new Guest Venom.
I think it is the lut named other1.png. It really does a nice job of adjusting the blues 
from more purply to more azure bluish.
Found some sharpness settings that I like. Scanline spike removal at 0.00 causes some nasty artifacts.
subtractive sharpness 1.00
horizontal sharpness 3.00
scanline spike removal 1.00
I think it would be appropriate to have this reference, although i tried to make the parameter descriptions informative, maybe less formal. It’s sure better to put more time and effort than less into this.
Thanks. I think i managed to avoid regressions, but probably won’t add more features, since the shader can be used with other nice shaders etc.
Uhh…that’s a tough one. When you integrate the overlay, then you are halfway trough though. the problem from my side is i’m not appropriate to do the fine tuning. 
That’s nice to hear. The upgrade shouldn’t be too hard, but it’s still a nitpicky work. Other custom lut’s are also easier to integrate, but torridgristle’s are reffering to characteristics of specific displays though.
Dunno why, but that’s my favorite combo also. 0.0 for scanline spike removal is maybe OK with the newer Smart Edge Effect.
New Release Version (03.01.2021-r1):
Notable changes:
I noticed some inconsistencies with lut’s and managed to fix them after a while, now it takes much less offset to patch a lut, which also means original contrast and saturation. Blue ramp shows better results on last two samples. Otherwise it’s much simpler to add and manage a custom lut now.

New Release Version (04.01.2021-r1):
Notable changes:
A bad regression crept in a while ago with substractive sharpness, which caused artifacting at edges and a sharper appearance where it shouldn’t.
Fixed now.
With recent versions i was more focused on other, filtering unrelated features, so it was here for a couple of versions.

Hey there!
All shaders use OriginalSize in the main shader pass because scaling goes abroad with prior shaders, so changing resolution of any of the passes has no effect on scanline density.
You can still use the hires and ntsc versions and set the scanline resolution to 240p with a parameter. The hires version is quite fine, if you only want 240p.
At 1440p should I be using hires or normal version? Thanks for the hard work btw, Its been YEARS i’ve been messing with shaders and yours is the first one that works clearly out of the box and other than some over saturation from scanline saturation and some gamma tweaks its pretty much set without having to have a degree is CRT.
Edit: Also ive been increasing Lottes maskDark (with mask 1) to give the picture a brigher image that somehow gamma settings just don’t quite achieve. Its a wierd work around but I have yet to see a real downside to it?
Ah, thanks. Also, what should the Mask gamma be? Same as gamma_in or gamma_out (I use 2.2 here)?
