To use Citra in portable mode with encrypted games, you need to place a file named aes_keys.txt in the sysdata folder within Citra's user directory. Content of aes_keys.txt
The aes_keys.txt file contains various encryption keys (such as Slot0x31KeyN, common keys, and BOSS keys) required to load encrypted .3ds, .cci, and .cia files. These keys are proprietary property of Nintendo and should technically be dumped from your own 3DS hardware using a tool like GodMode9. Portable Mode Setup
For a portable installation, the user directory is located in the same folder as the Citra executable. Navigate to your Citra folder. Open or create a folder named user.
Inside user, create a folder named sysdata if it doesn't already exist.
Place your aes_keys.txt file directly inside the sysdata folder. How to Obtain the Keys
Official Method: Use the dumpkeys.gm9 script in GodMode9 on a modded 3DS to generate the file automatically from your system.
Alternative: If you do not have the keys, many users recommend using a Batch CIA Decryptor to decrypt your game files before loading them in Citra, which bypasses the need for the aes_keys.txt file entirely.
Are you having trouble with a specific game error or just setting up the folder structure?
To make Citra portable—meaning it keeps all configuration files, save data, and aes_keys.txt in one folder (e.g., on a USB drive)—you must create a specific folder structure.
Important Note: Citra is a discontinued emulator. The following instructions apply to the legacy Citra desktop builds. Portable Mode Setup Locate your citra-qt.exe file.
Create a new folder named user in the same directory as the citra-qt.exe file.
Create the required subfolders inside the user folder:user/sysdata/
Place your aes_keys.txt file inside the user/sysdata/ folder.
Once this user folder exists, Citra will automatically prioritize it over the default AppData/Roaming directory, making the emulator fully portable. Troubleshooting
Encrypted Errors: If games still show as encrypted, ensure aes_keys.txt is properly formatted (lowercase) and placed inside user/sysdata/.
System Check: Ensure your CPU supports SSE4.1 and you have OpenGL 3.3 support. If you'd like, I can: Show you where to download the aes_keys.txt file Explain how to dump your own keys from a 3DS

Downloading a pre-made aes_keys.txt from the internet poses security risks:
If you are running Citra in portable mode (where a user folder exists in the same directory as citra-qt.exe), follow these steps to ensure your keys are recognized.
"Citra still says keys are missing!"
Double-check that you are editing the correct user folder. If you see a user folder inside the Citra installation directory, that is the one used for portable mode. Do not place the file in your Windows Documents or AppData folders.
"Where do I get the keys?"
We cannot provide links to download these files. This is a legal grey area that risks copyright infringement. The only supported method is dumping them from hardware you own using tools like nimds or similar homebrew dumping scripts.
The aes_keys.txt file represents a bridge between the complex hardware cryptography of the Nintendo 3DS and the software-defined environment of the Citra emulator. Its design as a plain-text, line-delimited file ensures maximum portability across operating systems.
While modern extraction methods involving boot9.bin have deprecated the need for manual text file creation, understanding the structure and portability of aes_keys.txt remains essential for debugging, legacy support, and the preservation of 3DS software in offline or portable emulation environments.
References:
The aes_keys.txt file contains the cryptographic keys required by Citra to decrypt "Encrypted" 3DS ROMs (often in .3ds or .cia format). While Citra can run decrypted games without these keys, many ROMs found online remain encrypted to protect copyright.
Without these keys, Citra will typically throw an error such as "The ROM is encrypted" or "Your ROM is missing an essential header." The file acts as a bridge, allowing the emulator to interpret the game data as the original hardware would. Setting Up a "Portable" Citra Instance
By default, Citra saves its configuration and data in your user profile folder (e.g., %AppData%\Citra on Windows). However, many users prefer a Portable Mode, which keeps all data, keys, and save files within the same folder as the emulator's executable. This is ideal for running Citra from a USB drive or keeping multiple versions separate.
Create the User Folder: In the main folder where your citra-qt.exe is located, create a new folder and name it exactly user.
Enable Portable Mode: Once that folder exists, Citra recognizes it and will no longer look in your AppData directory. It will now store everything—including your keys—inside this user folder. Where to Place the aes_keys.txt
In a portable setup, the file structure must be precise for the emulator to detect the keys: Path: [Your Citra Folder] > user > sysdata > aes_keys.txt
If the sysdata folder does not exist inside your user folder, you must create it manually. How to Obtain the Keys
Due to legal and copyright restrictions, emulator developers do not bundle these keys with the software. There are two primary ways users typically acquire them:
From a Physical 3DS: This is the recommended method. By using a homebrewed 3DS console, you can use tools like GodMode9 to dump your system's essential files, including the AES keys.
External Sources: Users often search for "Citra AES keys" or "3DS AES keys" online to find pre-compiled text files. These files contain hexadecimal strings that represent the different "Key Slots" used by the 3DS hardware. Common Troubleshooting
File Extension: Ensure the file is named aes_keys.txt and not aes_keys.txt.txt (a common mistake if "Hide extensions for known file types" is enabled in Windows).
Internal Content: The file should be a plain text document. Each line typically follows a format like slot0x2CKeyX = [32-character hex code].
Decrypted ROMs: If you prefer not to deal with keys, you can look for "Decrypted" versions of your games, which have had the encryption layer removed and will run in Citra without the aes_keys.txt file.
The Citra AES keys.txt file is a critical component for users of the Citra 3DS emulator who want to play encrypted Nintendo 3DS games. While many users prefer decrypted ROMs to avoid this setup, the portable configuration of Citra allows you to keep your keys and emulator settings in one self-contained folder, making it easy to move between computers. What is the aes_keys.txt File?
This text file contains specific encryption keys—protected by Nintendo—that the Citra emulator uses to decrypt and load game data in real-time.
