Here's what the end result looks like:

I tested with Animal Crossing. It runs at about half speed at best. (If you saw this tutorial on Reddit already, I did not steal this guide. I posted it there as well.)

I'm assuming you already have Arch running on your switch with SSH and Wi-Fi working. SSH isn't needed, but it's way easier to do this with SSH. If you don't have Arch set up, look here: https://gbatemp.net/threads/quick-tuto-how-to-boot-linux-on-your-switch.501918/ I would also suggest the precompiled version of the booting tools here https://github.com/SoulCipher/shofel2_linux

Please comment if anything doesn't work as I might have forgotten something (I did most of this last night so I'm pretty much trying to remember the steps I took).

First you should have the equivalent of build-essential or base-devel for your system.

SSH into the Switch and sudo su into root. Now run

pacman -Syu alsa-lib bluez-libs cairo enet gcc-libs gdk-pixbuf2 glib2 glibc gtk2 hidapi libevdev libpng libpulse libsm libx11 libxi libxrandr libxxf86vm lzo mbedtls pango sfml zlib cmake git

This will install Dolphin-emu's dependencies. Next, run

git clone https://github.com/dolphin-emu/dolphin.git dolphin-emu

Which will clone Dolphin-emu's repository to your Switch. Move into the dolphin-emu directory.

cd dolphin-emu

Now create a folder called Build and go into it.

mkdir Build && cd Build

Configure the build

cmake ..

After this is completed, run

make -j6

to compile Dolphin. Now run

make install

to install Dolphin on to the Switch.

Run it by typing dolphin-emu in LXTerminal on the Switch and pressing enter. You can type by using the "Onboard" program. Press the Config button, go to the audio section, and tap where it says ALSA. Change this to disabled. Close Dolphin and go back to your ssh session. Run

nano ~/.config/dolphin-emu/Dolphin.ini

and change where it says CPUCore = 1 to CPUCore = 4. This sets it to use the JIT64 DC, which is the fastest CPU interpreter for the Switch.

Now you can relaunch Dolphin and load a game!

Edit: To improve performance, try running

echo 0a > /sys/kernel/debug/dri/0/pstate

(Thanks, @natinusala!)

It gives this now.

Try installing base-devel?

Try installing base-devel?

That made it work now, thanks!

Try installing base-devel?

still didnt work

Dolphin plays wii games too, anyone tried skyward sword with joycons?

sorry but you need a special edited dolphin emulator that i found is only for windows for skyward sword
If you want your joy cons to act like a wii mote

Oh well, I wanna replay skyward but my shield TV didnt seem to work with joycons as M+ and this doesnt yet either, I can wait longer...

Help everytime i type make -j6 it crashes my system help

 

[LarBob]

still didnt work

What's it say now?

 

[ExploitTnT]

What's it say now?

it works until i type "make -j6" because it crashes my system

 

[LarBob]

Try make -j4 or -j3? Make shouldn't crash your system.. are you sure cmake completed successfully?

yes cmake completed successfully

Issue is that we dont have Vulkan Yet and Vulkan will give Dolphin a decent Speed Boost

 

[Sonicbrawler]

My switch keeps going to a black screen when im working on this. no idea what the cause is, as it randomly happens.

The better question is how to use the Wii U GameCube adapter on High Sierra & Win10Pro

thats easy to use it on windows

You say that but for me it doesn’t work. Maybe it doesn’t work for me because I’m using a hackintosh.

Tried VC Wads. SNES works fine but any N64 wad I try doesnt work.

Haven't tried any Zelda game. Although I did test Super Mario Galaxy 2. In terms of graphics, the game looks superb, but it runs like crap.

Try using just make. It'll take a lot more time to compile, but your system shouldn't crash. It happened to me as well.

I totally forgot about WADs. I'll test some of 'em right away.

Try downclocking to increase fps.
