What You Need to Get Started with Citron
Downloading the Citron emulator is only the first step. You also need a few essential files for it to run games properly:
- Prod.keys
- Firmware files
These must be obtained from your own Nintendo Switch console. They are not included with Citron due to copyright restrictions.
Citron Setup Guide 2025 – How to Set Up the Citron Switch Emulator
Follow the steps below to configure Citron correctly. Don't skip anything because if you do, you will have problems down the track, especially once you try to add games.
The Citron Emulator
Download the latest version of Citron from the official Citron website. Select the correct build for your operating system (Windows, Linux, or macOS) and extract the downloaded archive into a folder on your computer.
After extraction, launch the emulator by opening Citron.exe (on Windows) or the equivalent executable for your platform.
Keep Citron Updated
Citron is frequently updated to enhance performance, improve compatibility, and resolve bugs. Running an outdated build may lead to crashes or missing features.
To check for updates:
- Open Citron.
- Click “Help” in the menu bar.
- Select “Check for Updates.”
- If a newer version is available, follow the on-screen steps to install it.
- Restart Citron or your PC afterwards to apply the update.

You can also download the newest release manually from the official Citron website if you prefer to manage updates yourself.
Citron Prod.keys
Citron requires decryption files called prod.keys and title.keys, which are extracted from a real Nintendo Switch. These keys allow the emulator to decrypt and load games.
Once you have obtained your prod.keys, install them by doing the following:
- Open Citron
- Click Tools > Install Decryption Keys

- Browse to the folder containing your prod.keys (ensure they are unzipped)
After installation, Citron will recognize them automatically.
Note: If you update your firmware in the future, replace your current keys with a matching new set to maintain compatibility.
Citron Firmware
Firmware files are essential because they contain the Switch system components required for many games to function correctly. Without proper firmware, games may fail to boot or crash immediately.
To install or update firmware in Citron:
- Open Citron
- Click Tools > Install Firmware

Ensure that the firmware version matches your prod.keys version. Most reliable sources group these files together under the same version number for convenience.
Adding Games to Citron
Once the emulator, keys, and firmware are properly configured, you can begin adding games.
To add games:
- Open Citron
- Click the Add New Game Directory, then select the location where you have games saved.

- If you have subfolders, right-click the folder and check the scan subfolders icon.

You can also manage DLCs and title updates from the same settings menu. If you add or remove content, refresh your game list to ensure Citron detects the changes.
