Duimon - HSM Mega Bezel Graphics and Presets - Feedback and Updates

[SiriusVI]

Hey @Duimon,

I found this WIP Azahar core.

libretro core · azahar-emu/azahar@d6f50f7

This is great, because that would mean I can use Azahar with your shaders and won’t have to rely on ShaderGlass, which (if you remember) doesn’t work correctly with your 3DS shaders.

However, when trying to load one of your 3DS shaders with this core, RetroArch crashes.

Do you know if this is just because the core doesn’t work properly, yet, or could it be related to a different issue? I never had RetroArch crash on me for trying to load a shader before.

Thank you!

[Duimon]

Without a log I couldn’t even make a guess.

But if you can run this core, what’s stopping you from running Citra?

[SiriusVI]

I use my real 3DS nand with Azahar, so I can play online and access all of my legally purchased games. That is not possible with Citra.

Also Citra doesn’t have Vulkan.

I will provide a log asap.

I did not face this issue with either glcore nor vulkan (it could be related to this in some way).

However, there’s another solvable issue that I faced, it seems all 3DS presets are defaulting to HSM_FLIP_VIEWPORT_VERTICAL = "1.000000" regardless of the video driver, and since Azahar core can work with vulkan, there’s no flipping issue to begin with, and this setting is giving the opposite result by flipping a perfectly fine image.

There are 3 steps to solve this properly while keeping the relevant glcore fix in place.

Firstly, remove the flip parameters from Duimon’s 3DS scale params:

Secondly, remove the 3DS flip parameters from Mega Bezel folder (@HyperspaceMadness):

Thirdly, go to: "RetroArch\shaders\shaders_slang\bezel\Mega_Bezel\resource\param_values\core-defaults\video-driver_core\"

Create an empty file and name it “glcore_Azahar.params”. Then open this file with a text editor and add the the following:

#reference "../../viewport-flip/verticalflipped.params"

Duplicate this file for other 3DS cores too if they don’t have a fix already:

glcore_Citra.params
glcore_Citra2018.params

Hi,

I’m using your bezels for all handhelds - all look ace! On the (original) GameBoy bezel / shader there seems to be applied a sort of ‘streak’ across the screen which seems to be a way of implementing a form of screen glare.

Is there any way in the parameters to remove this so the screen was basically just ‘green’ with LCD and slight blur (ie just remove the streak / glare)? I can upload a photo later if that helps?

Thank you

[ShyTalk]

Here’s the photo to hopefully illustrate what i’m talking about:

[Duimon]

There should be no need to remove anything from the Mega Bezel, and If there is a flip parameter in my preset it is a bug that should have been removed when HSM added his wildcard method. I’ll take a look, and add the new core to my planned Mega Bezel hotfix.

Also, don’t be too quick to assume that every hit you get in your search is a bug. For example, if a hardware accelerated core is using glcore as a driver, it will flip even when it shouldn’t, and the Lynx core is wonky about when it flips or rotates.

Or they may be bugs, we’ll have to dig in and look.

[Duimon]

That is a background from the DMG shader that I borrowed. My intention wasn’t for the result to look like a Gameboy, but to try and look as much like the DMG shader as I could.

Another image could be referenced to get rid of it, but it would have to be a similar color. ( Maybe an intense gaussian blur on a copy of the existing image?)

@Duimon

There should be no need to remove anything from the Mega Bezel

That’s what I thought at first, but if you try to load one one of the presets in my screenshot (from Mega Bezel folder), you’ll get unnecessary flipping with vulkan driver. They seem like residual params from before wildcards, and only a handful of presets have them.

[Duimon]

After looking at bit closer, I would have to agree. Looks like HSM and I both missed a couple of baked in flipping parameters.

I will talk to him and probably include fixes for his presets along with the additional wildcard entries I have planned.

[Orionsangel]

Well to me this is the most authentic GameBoy dot matrix shader. Nothing beats It imo. At least in terms of authenticy. It legit looks like a real GameBoy screen. You can even add the blur if you like. There’s obviously other filters out there that may improve the visuals, but I always seek authenticity first.

This awesome filter was made by @Tatsuya79

Handheld Border Shaders

This is a portable pack of various handheld shaders. I made borders for existing ones and tweaked stuff around. Main differences with what you can find in the shader repository (because of file size constraint there): Some borders are less compressed DMG ones have a dithering applied to limit the bending of the glass light effect some tweaking in the parameters new stuff not added there Integer scaling should be OFF and display ratio on “full” to show the full border image. The scaling of t…

[SiriusVI]

That’s the one that comes bundled with RetroArch, right? The one in the handheld --> console-border folder?

I gotta agree that his DMG preset really is the best looking. Been using it for years. It’s basically the only non-HSM shader that I use.

@Duimon Wouldn’t you be interested in using this shader as your base for your Game Boy preset?

[SiriusVI]

Thx for the input and additonal info!

I’m not sure if the issue is related to “Black screen and crash after launching a game with a shader preset (with long reference)”.

If it were, what would be the fix? I don’t really understand the issue, tbh.

I set up a clean RetroArch install on the root of one of my drives to test, but it didn’t work there, either. Same issue.

Edit: @Duimon and @Starman99x

Here is the log file when trying to launch the Azahar core with the shader. Maybe you can make sense of it?

EDIT: 2

I got it working by forcing the API to OpenGL in the Azahar graphics settings. But when switching to Vulkan, I can’t get it to work.

Any idea why it would work with OpenGL and not with Vulkan?

[Duimon]

@SiriusVI

@Duimon Wouldn’t you be interested in using this shader as your base for your Game Boy preset?

Of course I would, but with the Mega Bezel, the shaders have to be surgically added by HSM.

The DMG was an option for about a year during the journey to v1.0 but was dropped for various reasons. Adding it back in was always on his list, but I think @kokoko3k’s dot matrix code looks quite good and is way more versatile than the DMG. Odds are much greater that HSM will integrate that instead at some point.

Authenticity is great but versatility is a Mega Bezel specialty.

[Starman99x]

@SiriusVI

If it were, what would be the fix? I don’t really understand the issue, tbh.

Just so you can be sure, try this version where they fixed that issue today (make it a separate installation, don’t replace your current one until the next stable release).

[SiriusVI]

@Starman99x I tried all three versions, but it didn’t solve my issue. Vulkan still crashes whenever I try loading any of the Duimon Shaders =/. Other shaders, such as simple CRT shaders, do work with Vulkan however.

Edit: Are you on Windows?

[Starman99x]

@SiriusVI Yes I’m on Windows 11. Did you try a different device? I noticed that Vulkan drivers can be picky sometimes. Try to test on a different PC/Phone if you can, preferably something higher end than your current setup. This had helped me figure out a similar issue before.

[SiriusVI]

I can try on my second PC, but my main one is pretty high end already, so I’m pretty sure it’s not a performance issue.

I should also notice that I don’t have any issues with other cores running Vulkan and Duimon shaders. It’s just this Azahar Core.

Which verson of the Azahar core did you try out? The latest one from Oct 1, 7:47 AM GMT+2?

Edit: @Starman99x since the issue appears on a freah retroarch setup with default settings, maybe you could tell me if you changed some settings that could affect this issue somehow.

Also, how did you configure your core options in Azahar?

[Starman99x]

Wait wait wait, I just encountered the crash myself:

It seems this crash happens with Vulkan + Nintendo_3DS presets.

But it DOES NOT happen with Vulkan + Nintendo_3DS_DREZ presets (my setup).

Glcore on the other hand, works well with both preset folders.

The log file shows no errors, this seems like a core issue. Maybe the dev can take feedback here where they are currently testing and reviewing the core. In the meantime, switch to DREZ presets, but first upscale the Azahar internal res (I’m using 2x). The DREZ presets will downsample the image back to the native resolution with the added benefit of some smoothing (similar to Anti-aliasing).

[SiriusVI]

@Starman99x Great find! DREZ works for me as well in Vulkan. Alright, so knowing that it’s not a setup issue on my end, I can wait patiently for core updates.

On a sidenote, what settings in Windows did you activate to get the error message window that you posted? On my end, RetroArch just crashes and I have to end the task. I never got any error message like you did.
