Question 1

What are “prod.keys” and “title.keys,” and why do I need them for Nintendo Switch emulators?

Accepted Answer

“prod.keys” and “title.keys” are cryptographic keys necessary for decrypting Nintendo Switch game files. These keys are essential for Nintendo Switch emulators like Yuzu, Ryujinx, and Skyline to run games properly, as they enable the emulator to decrypt the game’s data, which is encrypted to prevent piracy.

Question 4

Where to put firmware and prod keys?

Accepted Answer

Firmware and prod keys must be placed in the correct locations for a Nintendo Switch emulator to work properly. Prod keys, including prod.keys and title.keys, are stored inside the emulator’s system folder, where they allow the emulator to decrypt protected system files and game data. Most emulators provide an option like “Open Emulator Folder” to access this directory easily. Once the keys are placed in the system folder, the emulator must be restarted to recognize them.

Firmware files are installed directly through the emulator’s built-in firmware installation option, usually found under Tools, Settings, or Data Management. Instead of manually copying firmware files, users select the firmware ZIP or XCI file and let the emulator install it automatically. Using matching versions of firmware and prod keys is important to avoid errors such as missing firmware or failed game launches.
