Citra Aes Keystxt Top Official

To use encrypted 3DS games in Citra, place an aes_keys.txt file into the emulator's sysdata folder, located in AppData/Roaming/Citra/ on Windows or equivalent directories on other platforms. These keys can be generated from your own hardware using GodMode9 on a 3DS with custom firmware. For detailed installation steps, visit Reddit/r/Citra.

Navigate to [1:] SYSNAND VIRTUAL.
Select movable.sed → Copy to /gm9/out.
Go to [S:] SYSNAND CTRNAND → data → <your ID0> → sysdata → 0001000F → 00000000 → copy LocalFriendCodeSeed_B (not a key but helpful for decryption).

If keys are missing → show error: Missing AES keys in keys.txt

Validate key length (AES-128 → 32 hex chars, AES-192 → 48, AES-256 → 64)

A. Use Decrypted ROMs from Your Own Dumps

As mentioned – GodMode9 can output decrypted .3ds or .cia files that run on Citra with no keys file at all. citra aes keystxt top
