Notes and Comments

  • To calculate the file checksums (checksum of the compressed data)...
Read as signed int, remove the sign and - 1 and you have the crc32.
ie. if checksum = -165278610 then crc32 = 165278609.
  • The format uses ZLIB compression.
  • The format seems to have some differences between FlatOut 1 and FlatOut 2.
