If you prefer not to manage configuration keys across multiple devices, you can convert your physical games into decrypted .3DS ROM formats using GodMode9 before copying them to your portable drive. Decrypted files bypass the requirement for an aes_keys.txt file entirely.
If you have landed on this page, you are likely trying to run encrypted 3DS ROMs on the version of Citra, and you have encountered the dreaded "Missing AES Keys" error. If the user folder does not exist, simply
Once the file is correctly placed, you can launch citra-qt.exe from your portable directory and load any of your legally dumped encrypted ROMs.
Citra requires an external text file named aes_keys.txt containing the necessary cryptographic formulas to decrypt and read the game data on the fly. System archives ( sysdata , nand , sdmc
You can copy the entire folder to an external hard drive or high-speed USB flash drive and play your games on any compatible computer without losing your progress.
