What is Citra and what version do I need to play online on Android?
Citra is an open-source Nintendo 3DS emulator that allows you to run games from this console on multiple platforms, including Android. However, the official version of Citra available on Google Play does not include online multiplayer support . This means that if you want to play with friends or strangers, you will need to download a modified version of the emulator.
Currently, the most popular version for playing online games on Android is Citra MMJ , an unofficial modification that adds extra features, including the ability to connect to multiplayer lobbies. This fork of the emulator has been developed by the community and is updated independently of the official version.
Download and install Citra MMJ Android
Since this version isn't available on the Play Store, you'll need to download the APK from a secure source . You can find it through specialized forums or communities like Reddit, where other users share verified links.
Once the APK file is downloaded, simply:
- Enable the option to install apps from unknown sources on your device.
- Locate the downloaded file and run it to start the installation.
- Once installed, grant the permissions it requests when it starts for the first time.
Important: Although installing a modified version involves certain risks, if you use trusted sources and have an active antivirus, you shouldn't have any problems.
How does online multiplayer work in Citra MMJ Android?
Citra's online system doesn't use official Nintendo servers. Instead, it relies on connecting through multiplayer lobbies that emulate a local network . This means you can connect with other players who share the same version of the game and are connected to the same "lobby."
To connect with other people, you will need:
- A suitable configuration file where the room you want to enter is indicated.
- Know the room code and password (if any).
- A version of the game compatible with that of other players. Make sure you are using the same region and version number.
Steps to set up and play online on Citra Android
Let's go into detail about how you should configure everything to work correctly:
1. Create or join a multiplayer room
You can find posts with public room codes on Reddit and other forums. Alternatively, you can create your own private room and share it with friends. To connect, you'll need the room's IP address, port, and password . If you want to learn more about playing online, check out this quick guide.
2. Edit the Citra configuration file
A crucial part of the process is correctly configuring the “qt-config.ini” file, which defines which room to use. This file is usually located in the folder: /android/data/org.citra.mmj/files/citra-emu/config.
You need to open this file with a text editor and add or edit these lines under the [WebService] section:
[WebService] Token=your_token_here CustomServerHost=salas.citra.net
Note: To obtain a valid token, you need to link your emulator to an account on the official Citra website. While this function may vary between MMJ versions, some forks require it.
3. Start the game and connect
Once set up, open the game and go to multiplayer mode from the title menu (if the game allows it). You'll see a connection notification or the option to view online users. If everything went well, you should be able to see other people in the lobby and join their games .

Tips to improve your online experience
Your gaming experience may vary depending on your connection, hardware, and settings . These tips will help you have a smoother game:
- Always connect to stable Wi-Fi networks. Avoid using mobile data.
- Use the exact same version of the game as the other players.
- If you experience lag, lower the game resolution from Citra's options.
- Avoid running other apps in the background during gameplay.
Common errors and how to fix them
Some of the most common mistakes when playing online on Citra Android include:
- The room does not appear: Check that the address and port are correct in the configuration file.
- Short-term disconnections: This is usually due to an unstable connection. Check your network and try again.
- You don't see the other players: make sure you are using the exact same version of the game.
Online gaming alternatives: Hamachi and LAN servers
In addition to public rooms, there are other ways to connect multiplayer games:
Hamachi or similar applications allow you to create a virtual private network where all players appear as if they are on the same local network. For Android, there are specific VPN versions that achieve the same effect. This option is ideal when you want to play privately with friends.
Another option is to use local Wi-Fi connections if you're all on the same network. Some games automatically detect players connected to the LAN and allow matches without needing to set up external lobbies. You can also check out this Archero 2 guide for more information on online gaming.
Community Engagement: The Role of Reddit
Much of the information and support for playing online comes from the community. Subreddits like r/EmulationOnAndroid are a key source for discovering new versions of Citra MMJ, finding active lobbies, and resolving bugs . Although all this information doesn't come directly from the developers, the community has managed to keep support alive through tutorials, help threads, and YouTube videos.
In these spaces, users share solutions specific to phone models, Android versions, or even problems with certain games . If you have any questions during the process, don't hesitate to turn to these communities, where other players have likely experienced the same issue.

Which games work best in Citra Android's online mode?
Not all 3DS games behave the same in multiplayer mode. Some of the most compatible and popular titles online are:
- Mario barth 7
- Super Smash Bros 3DS
- Monster Hunter 4 Ultimate
- Pokémon Sun and Moon (although online battles may present more latency)
If you're planning to play with friends, it's best to try the game in single-player mode first to make sure it works correctly . Then, ensure everyone has the same version number and similar settings to avoid synchronization issues.
Compatibility and performance on Android phones
Citra online's performance on Android depends heavily on the device's hardware . To avoid problems, ideally you should have a phone with at least the following specifications:
- Mid-range or high-end Snapdragon processor
- 3 GB of RAM or more
- Good cooling to avoid performance drops after several minutes of gaming
Additionally, using quality ROMs and updated emulator versions improves the overall experience.
Thanks to community work and modified versions of Citra, online gaming on Android is entirely possible and, in many cases, quite fluid. While it requires a little more effort than on PC, the reward is enjoying your favorite titles with friends from anywhere. With a good guide, the right tools, and a little patience, starting online gaming on Android is more accessible than ever.
