Aeskeystxt Citra Portable Link

To use the Citra 3DS emulator in portable mode with encrypted games, you must create and place an aes_keys.txt

The Official Way

: The safest and legal method is to dump them from your own physical 3DS hardware using a tool like GodMode9 . A script like DumpKeys.gm9 will generate the aes_keys.txt on your SD card, which you can then copy to your portable Citra folder.

• File naming: The file must be named exactly aeskeys.txt (case-sensitive on Linux, but usually case-insensitive on Windows).
• Format: Each key should be on its own line in the format slot0xXXKeyY = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX (64 hex chars).
• Portable vs. installed: If you previously used an installed Citra, remove any old aeskeys.txt from %APPDATA%/Citra to avoid confusion when switching to portable.
• Legacy builds: Very old Citra builds might look for aes_keys.txt – check your version’s documentation.

• Configuration can be complex for beginners.
• Performance may vary with more demanding games on lower-end hardware.
• Some users might encounter compatibility issues with certain games.

This text file contains essential decryption keys extracted from a physical 3DS console. Without these keys, Citra cannot read encrypted game files (such as .3ds or .cia formats) and will typically display an error stating that the game must be decrypted first.
