How to Fix Citra MMJ Not working: Troubleshoot Guide
When you first successfully install Citra MMJ on your Android phone, you start playing the game excitedly. But after some time, you may start facing small problems. The FPS starts to drop, the game starts to lag, random freezes occur, or even your game progress is not saved. For some people, the headache starts even earlier. The app refuses to install after a successful download.
Honestly, every such issue feels frustrating, but most of these issues are not actually as serious as they appear to be. In many cases, they are caused by simple configuration mistakes, device limitations, or Android system settings that can be fixed easily if you understand what is happening behind the scenes.
Common Citra MMJ Issues and Their Fixes
We have tried to bring together the most frequently reported Citra MMJ issues in one place after going through Reddit discussions, GitHub issue reports, and real user feedback from the community. The goal is to provide convenience for our users so they can quickly understand an issue instead of visiting multiple sources or scattered threads.
On this page, we have briefly described the common issues along with their possible reasons. For deeper troubleshooting, we have created separate detailed guides for every issue, where each fix is explained clearly and in full detail.
Citra MMJ Not Opening on Android
Sometimes, after downloading Citra MMJ, when you tap the app icon, it doesn’t open, or if it opens, it immediately closes after a second.
The reason could be that you’re using an outdated Android version, you have installed a corrupted APK, or you skipped the storage access permission step during installation.
Another reason the app may not open is that you are trying to run a game from a game launcher or frontend app.
Citra MMJ Not Saving Settings
Some users report that the Citra MMJ Android emulator does not save in-game settings after they close the emulator. Settings such as performance hacks, in-game graphics settings, or per-game configurations may not be saved. Check out the detailed guide to understand the actual reasons and their fixes step by step.
Citra MMJ Not Recognizing SD
You can see the SD card in Android, but Citra MMJ behaves as if there are no games stored on it. In this situation, Citra MMJ can’t see your SD card or the games stored on it. This usually happens when you have not given permission to the emulator to access the SD card, or you have not correctly added the games folder on the SD card.
Citra MMJ Not Showing Games
You open this Android emulator, but no game is showing up in the library, even though the SD card is visible in Android. The possible reasons could be that you have not given storage permission, you have selected the wrong folder, or you have not saved the games in a supported format like .3ds or .cia that this app recognizes.
Citra MMJ Not Launching Games from Frontend Apps:
Another scenario where Citra MMJ does not launch games is when you try to play games through this emulator using a gaming launcher. The reason for this issue is mostly that the frontend app is not properly configured to launch Citra MMJ.
Citra MMJ Lag and FPS Drops
This is a very common issue on mid-range and older phones. You start playing games, and then slowly the FPS starts to drop. The game starts to stutter, lag, become unstable, or even freeze during long gaming sessions. High graphics settings, shader cache building, running many apps in the background, or overheating of the phone can be some reasons for this issue.
Citra MMJ “No Sound or Video (Black Screen)” Issue
Many users experience that while playing games, out of nowhere, their phone screen goes completely black. The weird part is that they can still hear the sound of the game, but nothing displays on the screen. A black screen is one of the most reported Citra MMJ issues.
The emulator works normally, but the game window becomes dark. Outdated drivers are one of the biggest reasons for this. Besides, incorrect GPU settings, a shader cache problem, or graphical rendering issues may also be causes.
Citra MMJ Multiplayer and Controls Not Working
Sometimes, while playing your games with this emulator, you observe that the controls are not responding properly in this app. Either you can see only a few control buttons on the screen, or you can’t see any buttons on the screen to control the game. Moreover, when you play with the analog stick, it behaves incorrectly.
In some cases, the multiplayer feature doesn’t work correctly or fails to connect between devices. Most people say that this app has dead zones. Other reasons could be incorrect input settings, screen scaling issues, or corrupted control layouts.
The reason for the multiplayer issue could be that the devices are not properly configured on the same network, or the feature is not fully supported in the version of Citra MMJ that you are using.
Citra MMJ Installation Issues on Android
The Citra MMJ emulator gets installed in a few minutes if everything is set up properly, but sometimes the installation process gets stuck at the same percentage for a long time. The installer seems to stop responding and feels frozen.
This doesn’t mean that the emulator is faulty. It works fine. The reason for this could be that your device is not compatible with this app’s requirements, or the APK file is damaged. Due to this, your device may take longer to verify and install the emulator, making the installation appear to be stuck.
After successfully downloading the Citra APK, when you proceed to install it, it gives an error message and refuses to install. If this happens, first check that your device is compatible with this app. Citra requires a 64-bit version, and it will not work on older 32-bit versions. Another culprit could be a corrupted APK file or insufficient storage space, which is blocking the installation.
Graphics Glitches After Enabling Hardware Shader
We all know that by enabling the hardware shader setting, the graphics improve. But sometimes, when you turn on this setting, a few minutes later, the game starts showing graphic glitches, missing textures, flickering, or other visual problems. Sometimes, the game even stops displaying graphics completely.
This issue usually happens when the game is not fully compatible with the hardware shader setting.
How to Restore Lost Save Files in Citra MMJ
If you ever update, reinstall, or switch this emulator to another device and panic that your game progress is lost, relax. The save files may still be present on the phone, but you can’t find them because Citra MMJ stores saves inside its data folders.
First, find the folder where Citra MMJ stores your save data. If you have a backup of your files, move those files back to the proper save folder and relaunch Citra MMJ.
Some users have reported on Reddit threads that all their game progress was lost when they uninstalled the old version before shifting to the new one. You must know that when you delete an app, all its data is also lost. So, you must back up your save files before updating or reinstalling Citra MMJ.
