Homebrew RetroArch Switch

[lordelan]

I'm getting an EXTREMELY specific, odd bug and I don't have any idea what the cause could be.

Playing Pokemon Crystal Clear on Retroarch nightly builds (through title redirect) will cause a crash whenever the Pokedex closes (on the white screen transition), but ONLY if shaders are enabled. Which shader doesn't seem to matter, although some shaders will crash Retroarch immediately when they're enabled. FTR I'm using either the Game Boy LCD shaders or the handheld border shaders on the libretro forums - not sure if those specifically are the problem.

These crashes do not happen on PC with the same shaders enabled, only on Switch. If shaders are DISABLED, no crash occurs, so it's specific to Retroarch on Switch AND the use of shaders. It's also a new issue. I've been able to use the Pokedex with identical shaders in the past without problems.

Unrelatedly (I assume), I've experienced crashes playing Banjo-Kazooie using the N64 core? That's also with shaders enabled. I have so far not experienced crashes playing Earthbound on the SNES9X core, again with shaders enabled.

I see you've just registered here to write this so you might register another time.
Because I recommend u to copy paste this into a github issue. They may want logs included (guess that can be activated in RetroArch somewhere).

No worries, after making the githhub report I tested a different core (sameboy) and it works without issue. Seems to be an issue specific to Crystal Clear and the gambatte core.

What core were you having issues with Crystal Clear?

Oh I thought I was replying to his previous post, where he mentions the shaders only
So Gambatte, I suggest trying other cores and see if they also fail or crash with shaders, and if they do, then post an issue for that on the RetroArch github.

Lol, he said they weren't happening under other cores. Are you paying attention?

He mentioned having crashes with Banjo on N64 with shaders enabled too, that's why I mentioned to be sure if it's a core issue or an RA one

You are right. His second post says something different.

Shaders work with sameboy and he already made a github report.

You told him to do something he said he did.

But he doesn't indicate any resolution about his N64 shader issue.

I'm inclined to believe that the issue with Banjo was just a random crash, as some N64 games tend to do so.
As long as he made the GitHub report, it should be good.
Hopefully the issue gets fixed soon.

But yes, I think the Banjo issue is completely unrelated, especially since my understanding is that N64 emulation in general and on Switch is prone to instability. I'll make a Github report if I continue to experience issues in Banjo.

Thank you everyone for your help!

Yeah my thoughts exactly.
The Banjo crash might have been related to the current state of Mupen64 Next, and not really related to the shaders themselves.
Still though, hope the issue gets addressed and fixed!

Understood!

I tried to play Chrono Cross on my Switch via Retroarch, but it just looks insanely bad, no matter what Shader I use.

I've searched online and found a AI upscaled texture pack for Chrono Cross, which actually looks really really good. The corresponding reddit posts talks about using beetle psx hw core and using the texture replacement feature. From what I have found I cannot use this core on nintendo switch (Though I found a beetle psx dyarec build, which does not load Chrono Chross though).

So my question: Is there anyway to use this texture replacements on the Switch? Any other idea what I could do to make the game look better?

Would be glad for any help

Thought you were talking about Chrono Trigger for a moment and I wanted to vomit.

The #1 problem for playstation is you can't get above 240p rendering right now on Switch. Improving the textures won't do jack without raising the resolution. Best shader I have seen for low-rez 3D PS1 stuff is the anti-aliasing ones, especially advanced AA.

Have you tried ppspp standalone. Much better:

I have not. I thought that this was only a PSP emulator, but if it works with PSX games too I will try it.
Can i use PSX games natively with this or do I have to convert them to an EBOOT (Like someone would do to run them on a classic PSP)?

 

[Rahkeesh]

PPSSPP will absolutely NOT run PSX games, even in eboot format.

You'd have to do the eboots. I can't say for sure that you'd have better results, but the PSP emulation is great compared to retroarch core--so I am assuming the PSX emulation follows suit.

My mistake.

Thank you @Rahkeesh

There isn't any announcement yet but 1.9.3 is now available.

Is it possible to have multiple user profiles on the switch version of Retroarch. I'd like to have a version set up for me, and also one for my son with access to different games, separate save files etc. I've installed retroarch to the main menu using nro2nsp, but it does not give the usual "select profile" prompt when starting up like other normal switch games.
