I got Yabause to compile (no, not the Mednafen Saturn core), and so far it's not looking too good.
I tried out the C4 2005 CD homebrew package by The-Rockin'-B, and it just loaded into a black screen, but only when I'm running the ISO. The CUE file just freezes on the Switch overlay.
I'm going to try out a commercial game — Daytona USA — and see if that runs, although I'm pretty sure it's going to be as slow as it always was. And yes, I'm aware of all the remarks about that.

@m4xw Not sure if it makes a difference. The nes core has save states load and save instantly. Not sure if the code is different or if that could help with the other cores or not just letting you know to check it out if that is the case.

IIRC the RA code used for SNES9x2010 & FCEUmm are the same.
(Unless his SNES9x2010 binary has things not committed to his repo)

Sounds like you had the same luck as me

Not sure just noticed it by testing and figured I say something.

Stella the Atari 2600 core seems to work perfect more or less as well.

Tested a few games and just runs not much else to say.

How dare you build Stella and not try E.T. first

Hahah jk, it's amazing to see more and more cores pop up with such amazing results!
I knew RA libnx would bring such goodies to the table

Oh I did just not in my video. Do not want to blast people who watch the vid with that title music

Code:

message: 40%: Loading state

Guess retroarch actually gives note about the Save state load process

Too bad we don't have on screen msg's yet

Yeah the screen msgs tell a lot if you turn them on and such.

Is it normal it takes like 20 secs depending on the game to load Or it could be improved? Also I really love GUI's if that gets implemented it will make me really happy.

Did anyone already try to compile Desmume or MelonDS?

Though I doubt Demusme have even a JIT backend, but I think MelonDS would be easier.

Greetings.

Don't even dream about yet that. Btw it seems that we don't get any fancy UI without shaders :/

Try uncommenting shaders from sources like in the 3DS/Vita ports.

And render them with what exactly?

Melon__Bread · Jun 4, 2018

O2EM is a Magnavox Odyssey & Philips VideoPac emulator. Requires some BIOS (o2rom.bin) places them in "/switch/o2emnx/"

(No video because the audio is blasting and too lazy to tone it down in a editor)

No issues to report.

The same way as rgui is rendered.

Thats not really how shaders work

(can't just throw them on the framebuffer)

I highly doubt rgui uses any shaders at all

And I am not gonna implement some dirty hacks to get it running through software shaders

Maybe it could work if we use SDL a video driver, but idk.

Shaders are not needed for Material UI nor for XMB (unless you want the waves on the background), that is because I say you can render those as the same way as you do on rgui.

I wouldn't say that if I didn't try that already.

I mean, shaders aren't used on the Vita port and yet it has the XMB menu working, so perhaps the issue has nothing to do with shaders.

Edit. Perhaps @Radius4 or @aliaspider may help you there.
