The GodMode9 method to obtain AES keys can also be used to dump other system files. Placing a boot9.bin (the 3DS's bootrom) and a secret_sector.bin (for New 3DS models) into the sysdata folder can enable even deeper system emulation and improve compatibility with certain games.
On Android, folder names are case-sensitive.
According to the r/Citra Guide , the legal and recommended way to get these keys is to dump them from your own 3DS hardware.
Turn off your console, remove the SD card, and insert it into your PC. Look inside the /gm9/out/ folder on your SD card. You will find files containing the essential title keys and system slots.

This indicates Citra cannot find the file or the keys inside do not match the specific game. Double-check that the file is named exactly aes_keys.txt and is sitting in the sysdata folder, not the root Citra directory.
Citra includes a command-line tool called citra-room (or citra-qt ) with a decryption flag.

This article provides a comprehensive breakdown of everything related to the aes_keys.txt file, including what it is, why you need it, where to place it, how to create it legally, and how to fix the most common errors. By the end, you will understand the mechanics of how the Citra emulator handles encryption and be able to solve "missing keys" errors on your own. The GodMode9 method to obtain AES keys can
aes_keys.txt file is a configuration file used by the emulator to decrypt and load encrypted 3DS games. Without this file, encrypted ROMs (like retail backups in
Citra can run decrypted files natively out of the box without requiring any external AES key configuration. To help clear up any remaining roadblocks, tell me:
Usually inside Android/data/org.citra.citra_emu/files/sysdata .
Despite following all the instructions, you might still encounter issues. Here are the most common problems and their solutions. According to the r/Citra Guide , the legal
Getting your aes_keys.txt file to work with Citra is a straightforward process once you understand the requirements. Remember these key points:
For Citra to reference the text file, it must reside in a specific system folder named sysdata . Depending on your device layout or your specific branch of the emulator (such as Lime3DS or PabloMK7's forks), the file paths differ.
So the keys file should go in:
