Downloading Yuzu or any other emulator is not enough to play Nintendo Switch games on Android and PC. You are also required to have the latest working or title keys to run the game. These prod keys are encryption keys that enable the emulator to decrypt and properly run game files. To play console games on PC or Android, you need three components: the emulator, firmware, and prod keys. The emulator provides the platform, firmware offers system files, and prod keys unlock encrypted data. Without the latest keys, the game won’t run correctly.
