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.
QuickBMS script
- flatout_bfs1.bms (created for FlatOut 2)
Supported Programs
- bfs2pack (+ source code)
- BFS Workshop / mirror1
- Game Extractor
- Game Archive UnPacker (GAUP plugin)
- Magic Extractor / Magic Packer
