However, there is a partial exception. For applications (like the Homebrew Launcher itself), no keys are needed. Additionally, some scene releases provide decrypted game dumps (often as RPX folders).

Frequently Asked Questions (FAQ) Q: Is downloading a cemu emulator keys.txt file illegal? A: Downloading keys for games you do not own is a violation of copyright law in many countries. Downloading a key for a game you legally own is a gray area, but safer. The only unequivocally legal method is extracting keys from your own console. Q: Can I play online with CEMU without keys.txt? A: No. Online play (Pretendo Network) still requires the base game to be decrypted, which in turn requires the correct key. Q: My keys.txt worked yesterday but not today. Why? A: You may have updated CEMU. Ensure the file is still in the correct folder. Also, check that no antivirus software quarantined or altered the file (antivirus rarely targets .txt files, but it can happen). Q: Do I need a separate keys.txt for each game? A: No. A single keys.txt can contain keys for hundreds of games, updates, and DLC. CEMU reads the whole file.

It then scans keys.txt for a matching entry. If a key is found, CEMU uses it to decrypt the game on-the-fly and run it. If not, the emulator will either crash, show a black screen, or display an error about missing decryption keys.
