I am no expert at scripting. My hope has always been that someone with real skill could take what I’ve done and make it something actually worth sharing. If you read the old posts, written while I was creating them, you’ll see I almost didn’t release them.

Hey, that’s the whole point of contributing!
Some have programming skills, some have graphic skills, some have little of either but lots of enthusiasm so they can help with housekeeping, documentation, data entry…

IMO If you are going for a base standard, I would go for 6504. Since you give the option, I think it’s not an issue.

My god housekeeping/documentation is always back burner-ed…

Help I’m new here, I downloaded the shaders and put them in the right folder but nothing is in the folders when Im in RetroArch. I can see the folders of the mega bezel shaders but there isn’t anything in them

Welcome to the forum!
This is probably because of the video driver you have set. To see the shaders you need to be using GLCore or Vulkan.
You’ll need to go to settings/drivers and change the video driver to one of these, then restart retroarch.
After you do this when you go to load one you should now see the shader presets

Thank you, I thought I did that but maybe it didn’t save I’ll try again maybe tomorrow. I didn’t know thats what causes the issue

I have adjusted the height and width, how do I adjust this line so it meets with the inner and outer corners??

[REFLECTION CORNER]
Corner Rotation Offset Top
Corner Rotation Offset Bottom
You can adjust one and then use the same value in the other.
There are a lot of other corner parameters you can also play with, like the Outer and Inner Spread. @HyperspaceMadness likes to give you a lot of control.

hi @HyperspaceMadness, got a “noob” question : i’ve seen some presets for 3DS/DS 2 screens shaders (from update 2 April) and i was wondering if it’s possible for Mame 3 screens like for Buggyboy or TX1 games ? … or it’s just impossible for the moment, don’t know 
Can’t find an answer in the thread, tks in advance

I started giving a look to your script.
Unfortunately I’m not a Windows user, so the most I could do was to read through the code to understand it and simulate some of it, but I could not have a real run.
From what I got, the end result is editing the *.slang file for a game to set
hmbz_bezel_color_hue = “0.000000” hmbz_bezel_color_saturation = “0.000000” hmbz_bezel_color_value = “10.000000”
values from the default to some new values calculated by inspecting the bezel images.
I’m not a graphic expert, so I have no real knowledge of what all this means. What does these values mean “in the real world” for my shader presets? What changes before and after?
Would you be so kind to share an image of a shader before/after the manipulation, please?
Thanks.

Hey there 
, yeah right now it only does a split of 2, but I could look at how hard it would be to split by three if it’s something you think you would use

There is nothing stopping you from doing the MAME 2 screen now, as long as the core doesn’t use a gap between screens it will just work.
3 screens would be cool but a lot of work for 4 games.

Question #1: Has anyone encountered a loading issue with Launchbox and using HSM with retroarch? When I pick a game from Launchbox it takes forever to load, and gives a blank screen twice before loading up the game.
Question #2: I was reading through the forum and I’m a bit confused on which preset to use and if I need to change the upscaling on any cores or leaving them upscaled and changing something in the shader in order for it to run smoothly. ( I’m thinking this might fix the issue to question #1 maybe?) I just want to run the games at 4k or 2k and not be upscaled even more from the presets. Thank you

One thing which may help us answer your questions, which cores and games are you trying to run?

Sorry, I didn’t test out all the cores but I tried Mame-current and snesx9 yesterday and they both did the same thing coming from Launchbox. I think it’s the resolution, it seems like my 1440p computer screen try’s to change resolution settings or something once it try’s to load the games. Like when you change the resolution in windows, it shuts off the screen and goes blank than it turns it to the chosen resolution
