It contains all necessary keys for different encryption slots (e.g., Slot 0x25, Slot 0x2C, Slot 0x2D).
: Some games load perfectly while others crash or fail to start.
When you encounter an encrypted .3ds or .cia file, Citra requires AES keys to decrypt the game data on the fly. Without a properly configured keys.txt , your games will fail to load—making this file essential for many users.
