Swuead Tutorial
How to install and run games on Ryujinx & Suyu
Before You Start
A decent PC
You'll need a computer with a modern CPU and at least 8GB of RAM. A dedicated GPU is recommended for better performance.
7-Zip or WinRAR
Required for extracting the emulator archives (.zip or .tar.xz).
Game files you legally own
You must dump your own game cartridges or digital purchases from your Nintendo Switch. We do not provide game files.
Switch keys and firmware (prod.keys / title.keys / .nca)
Dumped from your own Nintendo Switch console. These are required for decrypting game files. Search online for how to dump keys and firmware from your Switch or Search for the files yourself.
⚠️ Important
We do not provide game ROMs, firmware files, or encryption keys. You are responsible for dumping these from your own legally purchased Nintendo Switch console and games. Downloading these files from the internet is piracy and is illegal.
Installing Ryujinx
Extract the archive
Download Ryujinx from the Swuead downloads page. Extract the .zip file to a folder of your choice (e.g. C:\Emulators\Ryujinx). There is no installer — it's portable.
Install your keys
Open Ryujinx. Go to File > Open Ryujinx Folder then click the System folder. Place your prod.keys and title.keys files into the system folder. Restart the emulator after adding them.
C:\Users\USERNAME\AppData\Roaming\Ryujinx\system\
Install firmware (REQUIRED)
Games require Switch firmware to run. Dump firmware from your own console, then go to Tools > Install Firmware > Install from Directory/ZIP and select your zipped firmware folder (DO NOT UNZIP FOR THIS EMULATOR).
Add your games
Go to Options > Settings > and add the Game or DLC Directory to where your game files and DLCs are stored (.nsp, .xci files) then click save, obviously. They will appear in the main game list.
Run a game
Double-click any game in the list to launch it. You can also right-click a game for more options like managing updates, DLC, or shader caches.
Installing Suyu
Extract the archive
Download Suyu from the Swuead downloads page. Extract the .tar.xz file using 7-Zip (right-click > 7-Zip > Extract Here — you may need to extract twice since .tar.xz is double-compressed). Move the contents to a folder like C:\Emulators\Suyu.
Install your keys
Run suyu.exe once it's open you'll get a warning saying encryption keys are missing, this is normal until you provide them; Click file, then Open Suyu Folder then place your prod.keys and title.keys in the keys directory.
C:\Users\USERNAME\AppData\Roaming\suyu\keys\
Install firmware (Unzip first)
Click File, Open Suyu folder, then place every single file in your unzipped firmware folder, (they're .nca files), in the registered directory.
C:\Users\USERNAME\AppData\Roaming\suyu\nand\system\Contents\registered
Add your games
Double-click the empty game list area, then select the folder where your .nsp or .xci game files are stored.
Run a game
Double-click a game in the list to launch it. Right-click for options like managing updates and DLC.
Troubleshooting
Game shows a black screen or crashes immediately
Make sure your prod.keys are correct and match your firmware version. Try updating firmware or re-dumping your keys.
Very low FPS / stuttering
First-run shader compilation causes stuttering. Let the game run for a while to build the cache. Also make sure you're using your dedicated GPU (not integrated graphics) — check your GPU driver settings.
"Keys not found" or decryption errors
Double-check that your key files are named exactly prod.keys (not prod.keys.txt) and are in the correct folder for the emulator you're using.
Can't extract .tar.xz file
Use 7-Zip. Right-click the file > 7-Zip > Extract Here.
