Citra is a highly optimized emulator, but it does not natively include proprietary cryptographic keys due to legal and copyright restrictions. The Purpose of AES Keys
For Apple users, the directory is hidden inside the Application Support files: ~/Library/Application Support/Citra/sysdata/ Use code with caution.
The recommended and legal method is to dump these keys directly from your own 3DS hardware. : A 3DS console with GodMode9 installed. Process : citra aes keystxt top
Download a script and place it in sd:/gm9/scripts/ . Launch GodMode9, run the script, and wait for it to finish. The script generates the file at sd:/gm9/aes_keys.txt .

Keep your aes_keys.txt file safe and back it up. Every time you update Citra, ensure the file remains in the correct user folder. Without it, most games simply will not work.
If you want to avoid the AES key process entirely, you can use game files (typically in format). Decrypted files do not require an aes_keys.txt
: After placing the file in the correct directory, restart the emulator for the changes to take effect and for your games to appear. Alternative: Using Decrypted ROMs
