Citra is designed to play 3DS games, but it cannot legally include Nintendo’s proprietary encryption keys. The aes_keys.txt file is a text file that acts as a bridge, allowing the emulator to decrypt commercial games and system data (like Miis or Amiibo). Without these keys, Citra will likely show errors when attempting to launch encrypted titles.
If Citra still displays an encryption error after you added the keys, check the following:
If Citra displays an alert stating your game is encrypted, check the following: Can’t copy the link right now
Ensure the sys folder is nested directly inside the user folder ( Citra\user\sys\aeskeys.txt ). If it is accidentally placed in the root Citra directory, the emulator will ignore it.
The final file path must mirror this structure: [Your Citra Folder]/user/sysdata/aes_keys.txt How to Obtain Legal AES Keys
: The text file, or instructions for how to obtain it, will never be distributed on this page. Providing or asking for these keys directly is illegal as it facilitates video game piracy. Our focus is on the technology and the process of legally setting up the software.
In a standard (installed) version of Citra, the aeskeys.txt file is typically stored in the user data folder (e.g., %APPDATA%/Citra/ ). However, keeps all configuration and system files inside its own folder – usually /user/ – making it fully portable across drives or computers. Therefore, you need to place aeskeys.txt in the correct location for the portable version to detect it.
