Document describing the DUC (ARDS ME) formats (Note: The (A1, C0) etc are hex values) The DUC file format has no encryption etc, just a structure containing data displayed by the Action Replay's DataMax feature. It exists at the top of the save, with the following structure: [DUC Data] [Header] = 4 Bytes (00) [Game Name] = 23 Bytes (Containing characters and the rest consists of 00) [Separator] = 5 Bytes (A1, 00, 00, 00, 00) [Save Name] = 31 Bytes (Containing characters and the rest consists of 00) [Separator] = 1 Byte (00) [Save Description] = 70 Bytes (Containing characters and the rest consists of 00) [Footer] = 30 Bytes (29x00, and then C0) [Save File] = 216kb, 512kb etc... This data is only read by the DataMax feature of the ARDS ME, altogether the header consists of 164 bytes.
