How NFC Codes and Audio Files Relate

Each audio file in the firmware has a code that matches its filename (e.g. cfor → cfor.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.
