Switch Prod Keys New -
When The Legend of Zelda: Tears of the Kingdom launched, many users with old prod keys from firmware 15.0.0 could not run the game. Even after dumping the game cartridge correctly, their emulator reported:

Cause: Your prod keys file lacks keys for firmware 18.0.0+.
Fix: Redump from a Switch updated to firmware 18.0.0+.
