While Ryujinx LDN 3.1.3 was a popular build for local wireless multiplayer emulation, the original Ryujinx project was discontinued in October 2024. However, you can still set up the emulator in a portable mode to keep all your data (saves, shaders, and firmware) within a single folder for easy transfer between devices. How to Make Ryujinx Portable
To convert any Ryujinx installation (including LDN builds) into a portable version, follow these steps:
Create a "portable" folder: Navigate to the main directory where your Ryujinx.exe is located. Create a new folder there and name it exactly portable.
Move existing data (Optional): If you have already used Ryujinx, its data is normally stored in %AppData%\Ryujinx. You can move the contents of that folder into your new portable folder to keep your current progress.
Launch the emulator: When Ryujinx starts, it checks for a folder named portable in its directory. If it finds one, it will save all firmware, keys, and system files there instead of in your Windows user profile. Basic Setup Guide
Once you have the emulator files, you need two critical components to run games:
Prod.keys: These must be placed in the system folder inside your portable directory.
Firmware: Open Ryujinx, go to Tools > Install Firmware, and select your firmware file (usually a .zip or .xci).
Game Directory: Go to Options > Settings > General and click Add to select the folder where your .nsp or .xci game files are stored. Using LDN Features

The Ryujinx LDN 3.1.3 build is a specialized version of the Ryujinx Nintendo Switch emulator designed specifically for multiplayer connectivity. While the official Ryujinx project was discontinued in late 2024 following a request from Nintendo, the LDN 3.1.3 build remains a popular legacy version for users wanting to emulate the Switch's "Local Wireless" (LDN) functionality on PC. What is Ryujinx LDN 3.1.3?
The "LDN" in this build stands for Local Wireless. Unlike the mainline Ryujinx builds which focus on single-player performance and accuracy, the LDN builds include a custom matchmaking server that allows users to play games online by emulating a local network connection.
Online over Local: It tricks the game into thinking you are playing in the same room as your friends (Local Wireless mode) even if you are miles apart.
Interconnectivity: LDN 3.1.3 famously introduced support for ldn_mitm, allowing emulator users to play alongside real Nintendo Switch consoles that have custom firmware (CFW).
Performance Tweak: This specific version included significant stability fixes for titles like Pokémon Scarlet & Violet and enabled Splatoon 3 playability on AMD GPUs. How to Make Ryujinx LDN 3.1.3 Portable
A "portable" version of Ryujinx is highly desirable because it stores all user data—including saves, shaders, and system keys—inside the application folder itself rather than in the hidden AppData directory on Windows. This makes it easy to move the entire emulator to a different drive or a different PC without losing progress.
It looks like you're interested in a specific topic related to gaming and emulation!
Ryujinx is an open-source emulator for the Nintendo Switch, and "ldn" likely refers to a specific version or build of the emulator, possibly focused on experimental or development features. The "313" could indicate a specific build or commit number.
You're also looking for a "portable" version, which usually means a self-contained version of the software that doesn't require installation and can be run directly from a folder.
Here are some general points about Ryujinx and emulation:
Ryujinx and Yuzu: Ryujinx and Yuzu are two popular open-source emulators for the Nintendo Switch. Both emulators aim to allow users to play Switch games on their computers.
Emulation and Legality: The legality of emulation itself is a topic of debate. However, using an emulator does not inherently imply illegal activity. Playing games you've purchased on an emulator can be considered legal if you own the game. Distributing or downloading ROMs (game data) without owning the game or without the copyright holder's permission is considered illegal.
Downloading and Safety: When downloading software like Ryujinx from the internet, it's essential to prioritize safety. This includes downloading from official or reputable sources to avoid malware. Ryujinx LDN 313 — Portable Download (brief overview)
Portable Versions: Portable versions of software are convenient because they don't require installation. They can be run directly from a USB drive or any folder on your computer.

Title: Architectural Discontinuity and Distributed State: A Technical Analysis of Ryujinx LDN Build 3.1.3 Portable
Abstract
This paper provides a technical examination of the Ryujinx Local Wireless Network (LDN) modification, specifically focusing on the archival and functionality of build version 3.1.3 in its portable distribution format. As the official Ryujinx project faced cessation via DMCA action in late 2024, specific community forks and standalone builds became critical artifacts for the persistence of Nintendo Switch emulation. This document explores the network topology utilized by the LDN module, the significance of the "Portable" deployment model in the context of software preservation, and the specific versioning stability offered by the 3.1.3 release candidate.
Nintendo Switch emulation has advanced rapidly over the past few years. Among the top contenders in this space is Ryujinx, an open-source emulator known for its accuracy, stability, and unique features. One of its most groundbreaking features is LDN (Local Area Network) emulation, which simulates the Switch’s local wireless multiplayer.
The specific version Ryujinx LDN 3.1.3 has become a gold standard for many players due to its stability and performance in titles like Mario Kart 8 Deluxe, Super Smash Bros. Ultimate, Splatoon 2, and Animal Crossing: New Horizons.
But what happens when you combine LDN functionality with portability? You get the Ryujinx LDN 3.1.3 Portable—a version of the emulator that requires no installation, runs directly from a USB drive, and allows you to play LAN-enabled Switch games anywhere. This article dives deep into everything you need to know about downloading, setting up, and optimizing this specific build.
The second half of our keyword is "portable" . A standard Ryujinx installation integrates into your Windows registry, stores saves in %appdata%, and requires administrator privileges for certain features. A portable version, conversely:
Thus, a portable build of Ryujinx LDN 3.1.3 is the holy grail for LAN party organizers and traveling gamers.
Again: You must dump your own.
No legitimate guide will provide direct download links. Emulation communities will remove such posts.
Following the takedown of Ryujinx repositories, the "Portable" zip archive became the primary unit of preservation. Because it does not rely on an external installer script that may reference dead URLs or deprecated dependencies, the portable binary represents a "frozen" state of the software's capability. The 3.1.3 build is particularly sought after because it represents the last known stable iteration before significant codebase upheavals occurred within the community post-takedown.
The Ryujinx LDN 3.1.3 Portable takes all this and adds the ability to host or join local wireless games—all without leaving a trace on the host computer.

Use 7-Zip or WinRAR. Extract to a folder named Ryujinx-LDN-Portable on your desktop or external drive.
The folder should contain:
Ryujinx.exeRyujinx.LDN.exe (the LDN-specific executable)Publish/ folder (for LDN patching)portable folder (created on first run if configured properly)The portable build’s biggest strength is taking LDN anywhere. But what if your friend is across the country? Use a virtual LAN.
