If a user extracts aes_keys.txt from their own legally purchased 3DS console and uses it only to play their own dumped ROMs, several legal scholars argue this falls under fair use (17 U.S.C. § 107) for personal, non-commercial archival purposes. However, this defense has not been tested in court for 3DS keys.

Solution:

The Citra emulator, an open-source Nintendo 3DS emulator, requires cryptographic keys to decrypt commercial game ROMs. These keys are often supplied by users in a file named aes_keys.txt. This paper examines the technical necessity of this file, the methods by which users acquire it, and the associated legal risks under the Digital Millennium Copyright Act (DMCA) and international copyright law. While emulation itself is legal, the distribution and use of aes_keys.txt without explicit hardware-derived consent occupy a legal gray area. This paper concludes with best practices for lawful emulation.
