RetroArch Additions Shaders
#2477

Here’s an interesting case study I stumbled across… some DS games require you to rotate the DS between vertical and horizontal depending on what’s going on in-game. Hotel Dusk here literally does a complete 180 depending on whether the player is left or right handed.

I want to set up RetroArch so the user can hit a button and toggle through different DS shaders. That way they can toggle between vertical and horizontal in real-time without having to change the video rotation in the UI settings.

I have been trying to achieve this, but cannot see a way to alter per-screen rotation in the HSM DS shader settings. Is this possible? Like I say - I could alter rotation through RetroArch, but I’d much rather do it via a shader for convenience and sheer ‘wow that’s cool’ effect lol.

The way RA works now is if you manually load a shader preset, you can use the “previous” and “next” hotkeys to scroll through shaders in that folder.

Problem is that it doesn’t work when a preset is loaded automatically via core, game, or content directory preset. In that case it remembers the root shader folder.

I am hoping that HSM decides to do something about that in the future.

Thanks for this. I am actually aware of this - the ‘scrolling’ functionality is exactly what I have been tieing into. The problem - or what think is the problem - is that I can’t rotate individual DS screens through shader settings.

And yeah - I know there are some issues around RA identifying the shader directory. Have you seen this thread? https://github.com/libretro/RetroArch/issues/5398

…You can set the shader via the command line, but it doesn’t quite solve your problem :-/

Yeah, the second part of the problem will require a “flip screen before split” parameter or some such to be added.

Hey, thanks!

Actually I’m totally forgot about these HD-CORE presets! :man_facepalming:

Just checked previous releases and it seems like it’s been available since V 0.9.09 2021-05-02 release. Before that HD-CORE presets were introduced inside of Experimental folder. So they are indeed released as stable version.

Wouldn’t that require manual work in every Duimon’s preset that uses scalefx with 3 multiplier?

Hmm, I think if you do Rotate core image near the top of the parameter list, then set the dual screen core image split to split left/right instead of up/down this might work…

To rotate opposite directions you’ll have to use the flip vertical & horizontal.

Note, I tested this ane it does NOT work, I’ll probably have to add something which does this behaviour. Or adjust the way the rotate works.

#2483

If you mean switching the preset referenced by Duimon’s preset that’s correct.

I’m not sure if there’s a better solution for this, but doing search and replace on all the base shader presets every release is bound to run into problems as the base presets change a bit here and there as you just encountered.

@Duimon It might be worth having hdcore versions of the presets for the cores we know can run higher internal res.

In the shader ‘Dual-Screen-DS__BASIC__LCD-GRID.slangp’?

I haven’t been able to achieve this by changing values under ‘Flip & Rotate’.

I agree. I just need a list of cores and I will make it happen.

About the NDS stuff. I think the first scenario will just require switching from horizontal to vertical. Until we have a way to switch shaders with a hotkey doing it during gameplay will be cumbersome.

The second would require a new “Rotate 180 before split” parameter.

How will that happen exactly? I am unfamiliar with the preset. Is it Royale or a stand-alone shader?

It will be just another preset in the variations folder which references guest venom with specific settings

Maybe a problem on my setup, but the new versions of the HSM shaders make Flycast crash when applying them. Other shaders work.

I am noticing a lot less moire with the new dr.venom advance. With most shaders when using a curve i noticed some very obvious moire in the Mega Man Legends 2 title screen. With the new one though I don’t see much of anything. Great update!

Awesome, glad this is working better for you!

Can you get a log of what happens when it crashes?

#2492

Hi All, I have a request for anyone who runs Citra at a higher than standard res, e.g. 2x, 3x etc

Can you try out the downsampling preset for 3DS and let me know what you think? It’s here:

Dual-Screen-3DS__DOWNSAMPLE-NATIVE_MBZ__2__STANDARD.slangp
#2493

Thats exactly how i remember games looked in my 90´s crt tv

Using the basic 3ds + lcd grid preset here…

The bottom screen starts mirroring its side content, and the screens aren’t meant to be the same aspect ratio at any rate.

The shader is Dual-Screen-3DS__BASIC__LCD-GRID.slangp.

Sorry in advance if I’m doing something dumb here! I am using the regular Citra core.

#2496

Hmm this is weird, it looks like it thinks the top screen is in the bottom…

Can you send me a screenshot of what it looks like with no shader applied?

Maybe citra did an update and is no longer flipping the viewport?

Is the flip vertical set to on?
