Hmm. Didn’t think I could get rid of that black bar.
I changed Crop Mode to 1 now (Crop Black Only) and Black Threshold for “Crop Black Only” to 1 as well, black bar is still there though.
Edit: Ah, needed to change “Crop Bottom %” to 6.7 as well.
Now it’s gone!
Will this apply to every other Snes game as well, or is it different for every one?
These scanlines on the surrounding graphic.
Yep.
Did you also increase the Crop Bottom %?
Crop Mode 1
Crop Bottom % 6.30
Black Threshold 100
Seems to work for me.
By the way, are you using the latest RetroArch, HSM Mega Bezel Reflection Shader and Shader Preset/Graphics packs?
Ok, now I see it. I zoomed into my own screenshot as well.
So I’m guessing the shader isn’t supposed to touch the graphics at all? 
Correct. I am using the Nvidia 517.48 driver. I am willing to bet there is a bug in the driver but am not willing to test it ATM.
6.70 seem to be the bottom for me
And yeah, RA 1.12 latest stable. Latest HSM and your latest pack, and Duimons 1.0.0.0
Very possible, they have a lot of weird bugs sometimes. It doesn’t bother me for now though, still looks really good. I’m a bit reluctant myself to update to the latest driver which is 526.47.
But we’ll see if it goes away later then!
Possibly a bug here also. I am just not in the position to do any tests.
No worries, I’m not in the mood either to go bug hunting right now. We’ll just leave it for now!
By the way, I have a feeling you might like my CyberLab__RGB-Sharp__PVM-Edition.slangp preset just as much if not better than my CyberLab__RGB-Smooth__PVM-Edition.slangp preset. It’s very much like the RGB-Smooth one just slightly less upscaled to give it a bit more natural console and TV feel but it’s far from being overly harsh.
Don’t forget to try the OLED TV tweaks I mentioned previously.
I’ll check it out!
I did try those mask parameters you mentioned, but they looked… bad. I could have been messing with the wrong one’s though.
Either that or your TV is not in RGB 4:4:4 mode.
The difference is supposed to be very subtle. Almost imperceptible from a normal viewing distance but noticeable if you go up to the screen and look at the phosphors.
Changing the Mask Size to 1 is also very important if you change the CRT Mask to 12.
The only other change is the Mask Layout from 0 to 1.
Also, you should ideally be using PC labelled HDMI input and Game Mode. Also ensure that you have HDMI Deep Color enabled for your HDMI input.
You’re right. Not sure why but I was in YCbcC444, not in RGB.
I had some issues with a HDMI cable, but I got a new one, so now that’s working as well!
10m HDMI fiber optic cable 
That’s all done already
I love your slot mask presets with my LG C1 but I think you need to thicken up the scanlines. They are barely noticeable.
Thanks, which preset or presets are you referring to that have scanlines that are barely noticeable and on what cores is this happening?
Have you tried “CyberLab__Ultimate_Virtual_Slot_Mask_IV_OLED_CRT-NP2RTA__ADV.slangp”?
It uses the darkest and thickest scanline type.
You can make the scanlines in any preset more visible/thicker/darker by increasing the GSL Scanline Type value.
You can also try disabling Deconvergence and fiddling around with the beam width.
You can take a look at some of these photos of some real arcade slot mask CRTs that I took recently.
When an NES game is good, it’s really good!

This is also something you can do to make things less harsh/sharp.

Just wanted to say thanks to @guest.r, @HyperspaceMadness, @Dogway, @aliaspider, @Hyllian and all other shader developers who contributed to HSM Mega Bezel Reflection Shader and made this all possible.
I know it’s almost a year later but if you’re still interested in this, take a look at my new Le’Sarsh Composite and S-Video Slot Mask Presets and tell me if that’s D-Series like enough for you.
Be sure to use the corresponding Blargg Video Filter presets or Core Options Settings if the Shader Preset filename indicates that they should be used.
You can take a look at these new presets as well as they are much finer than the previous Slot Mask preset I’ve made.
It’s all in the settings so feel free to take a look and let me know if you still need assistance in getting CRT-GUEST-ADVANCE Slot Masks to look and work properly on your display.
Last time you said you were changing the settings and they were not doing anything. In order for them to have any effect, you first need to select a Trinitron mask type (5 through 12) then increase the Slot Mask Dark Pixels and Slot Mask Bright Pixels settings.
For LG OLED TVs you really should be using Mask Layout 1 if you want any mask to look correct in a close-up.
