Example result

Each field begins with a 2-byte ID and 2-byte payload length. Advance by that length and repeat.

55 54 05 00 identifies field 0x5455 with a five-byte payload.

This checks outer field lengths and exports raw data. It does not validate each field’s internal schema or decompress archive content.
