How NFC Codes and Audio Files Relate

Each audio file in the firmware has a code that matches its filename (e.g. cforcfor.mp3). When the remote or robot reads an NFC chip, it looks up this code and plays the corresponding file. However, some NFC chip codes are composite — they don’t have their own audio file. Instead, the device splits them into a sequence of existing files to save firmware space. The full list of physical NFC chip codes and kit contents is in Command Chips.
