Homebrew RetroArch Switch

I was thinking earlier, something cool that RetroArch needs is the ability to have two config presets that maybe you can assign to docked and handheld mode.
So for example, you might have a config preset that uses a 720p resolution, JoyCons for input, etc, which you set as the "handheld preset". And then you can have a 2nd preset that it seamlessly switches to when you dock the device, that maybe uses 1080p res, possibly a scanline shader, and maybe the Pro Controller as the input.

I don't think they would include any Switch specific specials features like that.
However you could have all cores two times on your SD (Snes9x_handeld.nro + Snes9x_docked.nro for example) and save some adjustments "per core" for those.

No point in doing that when you can just save config presets and manually switch yourself. Plus also, the idea is to be able to dock and undock the device without interrupting gameplay, which actually you can already do minus the config changes.

Oddly beetle crashes on me completely when I try to use it.

No white screen or anything, just the black error screen telling me to power off the switch.

PSX ?

Finished Chrono Trigger Retroarch on the Switch a few days ago - trying to get the Epoch crash ending, the game reproducibly crashes when the game tries to go into Epochs cockpit perspective (mode 7?). The other ("normal") ending plays fine though.

Moonlight parade e/o.

i was able to build an Snes9x core with Devkitpro , if somebody could help me fix the makefile.switch for RetroArch we could try to make a test build to see if it works (libnx) the makefile.switch needs to be rewritten

Is this true? Do you have the code on GitHub somewhere?

Update:
@misson20000 also got a toy dynamic loader into libtransistor, paving the way for dynamic cores in RetroArch and traNVparency improvements. See PR

this project isnt dead friends

Reading through the latest news post from Retroarch I noticed Readahead has been added to a bunch of platforms.. Including Switch

I tried it on the WiiU and for the most part works really well. For people who dont know what Readahead is you can find more info here: https://www.libretro.com/index.php/category/blog/

There's no official Switch download yet or anything but I'm posting it to show things are still moving on the Retroarch Switch front

Looks like they've forgot to release the Switch version, I think.
Hope they put it out very soon. Been waiting ages for it.

I did notice the PR for the Switch but was like

How if we don't even have nightlies for the Switch yet? XD

traNVparency is the GPU drivers right?
Or am I getting it wrong?

Any update on getting mame roms to work on hardware? specifically mame2003? using the search feature, I saw we hit a roadblock regarding zip files.

Can someone explain to a noob why the DS emulator a still really slow? It’s just suprising that we have PS1 but we don’t even have the fricken DS (i just wanna play some pokemon :cry:

)

Because emulation isn't magic and needs to be optimized.

We have PS1? I've been unable to get it to run at all.

DSemume is fairly demanding and doesn't really run fullspeed without an interpreter/dynamic recompiler on the target platform. Guessing that isn't available for switch (yet)

Works well in Linux

Linux has HW acceleration and open GL going (if you are on the right build), so thats likely the differentiator.

Also the Switch team got that "for free", because the driver implementation for the X1 was already part of the Linux stock.

Thats why we are seeing those kinds of advances under Linux while Libreto is making it public that "the" Retroarch build on Switch is still libtransistor based - which doesn't currently have any HW acceleration.
