63The old description would also assume 12 byte reference blocks but a packed struct 63If the .dat file has a version of 01.03 or later, the corresponding .tad file looks like this:

65 uint32_t offset
66 uint32_t size // with flag in upper bit, 0 -> large record
67 uint32_t checksum // but sometimes just 0x00000000, 0x00000001 or 0x00000002
68 uint32_t unknownn // mostly 0
