Ryujinx Fork Setup Guide for Linux

Ryujinx Fork Setup for Linux

Install and Run a Ryujinx Fork with LDN Multiplayer Support

Ryujinx is a high-performance Nintendo Switch emulator, and while official development has slowed, community forks such as the GreenDev build continue to provide stable updates, including support for LDN multiplayer.

This guide explains how to install, configure, and use a forked Ryujinx build with LDN on Linux, including how it differs from the official release and how to enable multiplayer.

What is a Ryujinx Fork?

A fork is a version of Ryujinx that is maintained by the community and is based on the same source code. These builds commonly include:

Continued development after official releases end.
Enhanced game support or emulator performance
Built-in LDN multiplayer features.
Bug fixes and system tweaks.

The GreenDev fork is one of the most reliable builds in the community, particularly for users who want to keep Ryujinx up to date on Linux with multiplayer support.

Why Should You Use a Fork in Linux?

While the official Ryujinx LDN build (v1.1.1403) is stable, forks such as GreenDev

Include ongoing updates and tweaks.
Provide better compatibility with newer distributions and drivers.
Maintain functional LDN support.
Use the same interface and file structure, so there is no learning curve

If you use Linux and want the best long-term support, creating a fork is a practical option.

System Requirements

Ensure that your system meets the following minimum requirements:

Minimum:

OS: Ubuntu 20.04+, Fedora 36+, Arch-based, Pop!_OS, and so on.
Memory: 8GB RAM.
Graphics: Vulkan 1.2 or OpenGL 4.5-compatible GPU
Required files:
- prod.keys (from your own Nintendo Switch)
- Game files (.XCI,.NSP, or.NRO)
- Optional: Firmware for complete compatibility.

Step-by-Step Setup for Ryujinx Fork on Linux

Step 1: Download the Ryujinx Fork

Download the most recent Ryujinx fork with LDN support:

Download Ryujinx Fork with LDN (Linux).

Choose between the.tar.gz and AppImage formats. Both support LDN.
After downloading, follow the extraction or execution instructions provided below.

Step 2: Extract and Launch the Emulator

Option 1:.tar.gz (recommended for manual configuration)

mkdir -p ~/Emulators/RyujinxFork

tar -xvzf ryujinx-*.tar.gz -C ~/Emulators/RyujinxFork –strip-components=1

cd ~/Emulators/RyujinxFork

./Ryujinx

Option 2: AppImage

chmod +x ryujinx-*.AppImage

./ryujinx-*.AppImage

Move the AppImage to ~/Applications and create a desktop shortcut.

Step 3: Install Dependencies (if required)

Ryujinx forks frequently use the same dependencies as the official build. If you encounter missing library errors:

Ubuntu/Debian:

sudo apt install libgtk-3-0 libopenal1 libsdl2-2.0-0 dotnet6

Arch/Manjaro:

sudo pacman -S gtk3 openal sdl2 dotnet-runtime

The emulator requires.NET 6+ to run.

Step 4: Install prod.keys and Firmware

Open Ryujinx.
Click File > Open Ryujinx Folder.
Open the system folder.
Upload your prod.keys file here.

Default path:

~/.config/Ryujinx/system/prod.keys

Then install the firmware:

Go to Tools > Firmware > Install from XCI/ZIP.
Choose your firmware .zip or a non-trimmed .XCI
Confirm and await the success message.
Your system version will now be displayed in the bottom-right corner.

Step 5: Add Your Game Directory

Navigate to Options > Settings > General.
Click Add under Game Directories.
Select the folder containing.XCI,.NSP, or.NRO files.
Click “Apply”

Your game library will be displayed in the main window.

Step 6: Use LDN Multiplayer in the Fork

Despite using a fork, LDN multiplayer is available:

Launch Ryujinx.
Go to Multiplayer > Open the LDN Room Browser.
Accept terms when prompted.
You can join an existing room or create a new one from the menu.

This behaves identically to the official Ryujinx.

Step 7: Play Multiplayer Games with LDN

Once inside an LDN room:

Launch a compatible game, such as Mario Kart or Smash Bros.
Select Local Wireless Mode.
Join or create an in-game lobby.
All connected players should appear.

Ensure that:

Everybody uses the same build.
Game versions and updates match exactly.
Mods are disabled or synchronized between players.

Safety and Compatibility Notes

Only download forks from trusted sources, such as GitHub.
Avoid combining forks and official builds in the same multiplayer room.
You can keep both builds separate for flexibility.
Your saves, firmware, and prod. keys are usable across all builds if the structure is preserved.
