The BTB file consists of chunks of the form:
struct CHUNK_HEADER
{
unsigned int chunkType;
unsigned int chunkSize; // excluding header
};
Each chunk consists of 'records' which are similar to chunks, but the record size is *inclusive* of the header.
struct RECORD_HEADER
{
unsigned int recordType;
unsigned int recordSize; // including header
};
The observed format of the BTB files in Dark Omen follows in order:
START/END CHUNK, type=0xBEAFEED0, size=0 HEADER CHUNK, type=0, size=<varies> UNKNOWN CHUNK, type=1, size=<varies> OBSTACLES CHUNK, type=2, size=<varies> REGION CHUNK 0, type=3, size=<varies> REGION CHUNK 1, type=3, size=<varies> . . . REGION CHUNK n, type=3, size=<varies> GAME OBJECT CHUNK, type=4, size=<varies> START/END CHUNK, type=0xBEAFEEDO, size=0
