Here are what I think you are looking for:
- [ FRAME ]______ / Opacity
- [ BEZEL ]______ / Width
- [ REFLECTION ]______ / Global Amount
- [ BEZEL ]______ / Outer Corner Radius Scale
- [ BEZEL ]______ / Height

Many thanks for the info. Everything worked, apart from 5 point. After removing Frame (opacity - 0.00) I need to increase default screen size to occupy the original size (but without frame). Seems like this is controlled via [SCALING] - Non Integer Scale
Is it the correct item?

Hello All,
I’m new here and recently decided to give emulation another look. These shaders look very nice, so I decided to give them a go. Alas, the fun and games of figuring all of this out decided to kick in and I have an issue I hope someone can give me a steer on.
I followed the instructions, driver is set to Vulkan, aspect ratio is 16:9 for my 16:9, 1080p monitor. Downloaded the files and threw them into the slang shaders folders.
The issue is that I can only load the Basic Shader Preset and any of the other presets (with all of the fancy settings) give me a “Failed to Load Shader Preset” error.
I’m on PC, with a GTX 1070 in the rig. Any idea why I’m getting the failed to load error and what I can do about it?

Yeah if you want the screen to actually be bigger yes this is the one

Can you take a look in the readme in the Mega_Bezel folder and follow the instructions to turn your log on, then you can post your log here so we can see why it’s not loading.
Also just to be sure, can you also take a screenshot of your windows explorer tree/path so I can validate that stuff is in the right place?
And welcome to the forum!

Thanks for the quick reply. Here are the error messages from the log, let me know if you need more from the log to help:

No doubt I’ve done something stupid…been battling with RetroArch config issues the last while…all part of learning this stuff I guess! I tried to update RA for the first time for these shaders and didn’t go very smoothly.
Thanks again and appreciate the welcome!

Thanks for the log, this helps me know what’s going on 
this line tells me you put the shaders folder INSIDE the shaders folder. Basically the folder structure in the zip is a mirror of what your shaders folder is from the root, so if instead of pasting the shaders folder inside the existing shaders folder you can paste it in the retroarch folder and everything will match up.
I think I might change the distribution zip to just have the bezel folder and instruct the user to place this inside your existing shaders_slang folder as a few people have had the problem you are having.

Thanks for the clarification. So basically we’re saying to replace the existing shaders folder entirely with the shaders that folder contained in your zip?
An alternative suggestion for you, perhaps you could add a line to your instructions to clarify that point.
I appreciate how challenging it can be to explain these things to all people in one go.
I’ll make the change later today and report back to let you know it’s working.

Yeah it doesn’t really replace the shaders folder though, just adds to it

And we’re in business…all is working now! Thank you for the help.
The method for adding the shaders is actually really simple once you know how! I think it is slightly foreign to a newbie who’s unsure of how RA folders work / behave.
I look forward to getting my self lost in shader parameters and tinkering until I break something else ha

Could you please help with color alterations for the Dual-Screen-DS__MBZ__2__STANDARD__LCD-GRID
Basically I would like to have colors identical to Dual-Screen__MBZ__2__STANDARD__GUEST-DrVENOM but with LCD pixel/Grid feel How can such config be achieved?
Thank you in advance!

Which colors do you mean, the screen? or the Bezel?
Could you provide some screenshots showing what you are trying to do?
Edit: Ok I re-read your message, you are trying to have the same colors as the standard screen but with an LCD feel… I don’t need any images…
You can adjust the parameters at the end of the list to adjust gamma and color correction.

Hmmm, I am trying to compare the two mentioned configs, but they seem to differ a lot. Maybe you have some figures for gamma and color that are considered as a default color correction (from standard screen)?

Since they are different crt shaders (Guest-DrVenom vs LCD-Grid) the coloring and gamma can be totally different so I would adjust the settings at the end of the list to get what looks better to you.
After this you can tweak the large number of settings in the Grade portion of the shader which is above the LCD settings.

Hi, thank you for this shader, but I have a problem: in my Retroarch, the shader does not scale automaticaly in vertical screen games (MAME-Dig Dug for example). I uploaded images to show what happens:
I’m sure that I followed the install instructions correctly (Vulkan, 16:9, Integrer OFF). Can you help me?

Hi and welcome to the forum, can you turn on the resolution debug info and take a screenshot?
I’m curious as to why this is happening. If you haven’t changed any settings this means that the core is outputting a very wide image…
And this is Mame, not FBNeo?
Edit: Looking at your image again this looks like a core auto rotation problem. Check in the core settings and see if it has options for core rotation. Basically we don’t want the core to try to auto rotate the viewport on us which it seems to be here

Thank you for the answer! It’s MAME 2003-PLUS.
Here is a screenshot with resolution info:
Changing the shader parameters:
orientation vertical (2.00) type 4:3 (2.00):
- Core Rotation Off
Result:
Did I do something wrong?

The core rotation I’m talking about is in the core settings, not the shader parameters. There is something going on with the core that it is rotating the viewport which is causing this stretching.
Do you have any rotation in the RetroArch Video settings?
I just loaded it up
For things to work properly the game should look like this with no shader applied
It is probably this option in the core options (options item in the quick menu)
this should be off like in the image
Once you get that working you will load the mega bezel and use the rotation parameter in the shader settings to rotate the screen.
So if you adjust the settings like in the image, rotate, flip vertical and flip horizontal

It worked! Thank you!

Did you ever fix this? I cannot apply the preset to a brand new Retroarch install 1.9.1 or 1.9.0
