With your legally dumped aes_keys.txt in hand, the final step is to place it in the correct folder for the Citra emulator:
Most 3DS games are protected by , a security measure designed to ensure they only run on official hardware. While Citra is a powerful emulator, it does not ship with these proprietary keys due to legal and copyright protections.
The official and safest way to generate the content for this file is by using on a hacked 3DS console: Run GodMode9 : Launch GodMode9 on your 3DS. aes-keys.txt citra
Navigate to the sysdata folder (if it doesn’t exist, create it inside the user folder).

"Do it right," Leo muttered to himself. He pulled out his old, battered 3DS—the one with the peeling Pikachu sticker. This wasn't just about playing a game; it was about the ritual. He connected the handheld to his PC, his fingers dancing across the keys as he initiated the decryption process. It felt like digital archaeology, brushing away the layers of encryption to reach the preserved artifacts beneath. Slowly, the file began to take shape. aes-keys.txt .
By understanding the role of aes-keys.txt in Citra, users can enjoy playing 3DS games on their computers while also being aware of the importance of respecting intellectual property rights.
He dragged the game file over the Citra icon. The emulator’s log window scrolled frantically—thousands of lines of code decrypting in real-time. Then, the black screen flickered. A familiar chiptune melody, slightly distorted and eerie, filled the room. The title screen appeared, but the characters weren't from any game he recognized. They were silhouettes, their eyes glowing with the same neon blue as his monitors. Step-by-Step: How to Legally Extract aes-keys

As part of this, the developers also agreed to shut down Citra, their 3DS emulator.
Within GodMode9, you can navigate to SYSNAND CTRNAND or SYSNAND TWLNAND and locate the console's secret keys. You can then use GodMode9 to "Dump" the system keys, generating the exact aes-keys.txt file needed for the emulator.
When emulating games, Citra requires access to the console's (such as Slot0x2C or Slot0x25 keys) to decrypt game data on the fly. These keys are stored inside a simple plaintext file named aes_keys.txt . Encrypted vs. Decrypted ROMs CITRA: bios support for AES Keys · Issue #270 - GitHub
