Common Citron Emulator Issues & How to Fix Them

Like most Nintendo Switch emulators, Citron is still a work in progress. It runs many games smoothly, but that doesn’t mean everything works perfectly for everyone. Issues can show up depending on your PC or phone hardware, graphics drivers, system settings, or even how your game files were dumped. The sections below cover the problems users run into most often and explain how to deal with them in a straightforward way.

Citron Emulator Not Launching

In some cases, Citron does not open, or the emulator shuts down shortly after. It is likely that the fault is with your system configuration and not with the emulator. The situation is usually caused by missing dependencies, obsolete drivers, or OS incompatibility.

Solution:

To be on the safe side, check if your PC has at least the minimum system requirements. If you are using Windows, ensure that the most recent Visual C++ Redistributable is installed, as Citron relies on it for its proper functioning. 

You have to update your GPU drivers, whether they are NVIDIA, AMD, or Intel. It usually resolves the issue of launching the application instantly. It can be a good idea to run Citron as an administrator as well as disable background applications.

Games Not Showing in Citron Library

Sometimes Citron may launch properly; however, your games will not show in the library. The problem is mostly related to either file directory or format.

How to fix it:

You should check that the formats of your game files are among the supported ones, which include XCI and NSP. And they are not packed or compressed in any way. Go to the settings in Citron and perform a re-scan of the directory where your games are kept to update the library. 

If a certain game is still not visible, it might be that the dump is either incomplete or damaged. Just remember to always verify that your game files are dumped properly and you have obtained them legally.

Citron Emulator Crashing During Gameplay

Experiencing crashes every now and then in between playtime is annoying, particularly when they occur out of nowhere. The main causes of the majority of the crashes are the video settings, inadequate hardware resources, or unstable features in the experimental department.

Things to try:

The first thing you can do is toggle between Vulkan and OpenGL, because there are some games that are more compatible with one of the backends than the other. Another thing you can do is to cut down on internal resolution or remove heavy shaders, all of which can positively affect stability. 

If your system is running low on RAM or VRAM, then closing the other applications running in the background can result in a significant difference. It is also advisable not to engage in experimental settings unless you are troubleshooting a certain problem.

Low FPS or Performance Drops

If the games are working but they are laggy or losing frames a lot, the issue is likely related to performance tuning and not to compatibility.

Solution:

One of the best ways to improve graphics in most titles is to enable Async GPU Emulation, which will smoothen the gameplay on the latest hardware. Vulkan is generally the best option in terms of performance for newer GPUs, so it’s definitely advisable to use it as your default backend. 

Lowering the resolution scaling is a very efficient way to cope with the most taxing games. Besides that, let the emulator compile shaders for you. In it, initial stutter is normal, and it usually gets better after a couple of minutes of playing.

Audio Issues

In the case of Citron, audio issues are frequently connected to the backend choice or the load on the system.

What you can do:

Change the audio output backend in the emulator settings and then restart Citron. If you are using a computer with limited capabilities, the closing of applications that are heavy on CPU could also be beneficial. 

If you want to continue hearing audio crackling, reducing the emulator’s resolution or speed settings can be used to stabilize the sound output.

Citron Emulator Black Screen on Launch

When you launch a game and a black screen appears, it mostly means that there are some incorrect or missing system files.

Solution:

Make sure the necessary firmware files are installed correctly and that prod.keys and title.keys are in the right folder. If the problem occurs only with one game, try to start a different one to check if the issue is related to that specific game. Sometimes the support for certain game builds just isn’t there yet.
