Open the folder. If it does not exist, create a new folder and name it sysdata . Paste your aes_keys.txt file inside this folder.

A key part of the legal argument was that the emulators used these cryptographic keys to circumvent Nintendo's "technological protection measures," which is prohibited under laws like the DMCA.
