DAT (TYPE 1 - NO COMPRESSION USED)
- Format Type : Archive
- Endian Order : Little Endian
Format Specifications
char {4} - Header (TERF)
uint32 {4} - Directory Offset (64)
uint32 {4} - Unknown (83886594)
uint16 {2} - File Padding Size (64)
uint16 {2} - Number Of Files
byte {48} - null
char {4} - Directory Header (DIR1)
uint32 {4} - Directory Length (including these 2 fields)
// for each file
- uint32 {4} - File Offset (relative to the start of the FileDataHeader)
- uint32 {4} - File Length
byte {0-63} - null Padding to a multiple of 64 bytes
char {4} - File Data Header (DATA)
uint32 {4} - File Data Length (including these 3 fields)
byte {56} - null
// for each file
- byte {X} - File Data
- byte {0-63} - null Padding to a multiple of 64 bytes
MultiEx BMS Script
Not written yet
Notes and Comments
NOTE: Files with length=0 still incur padding, so are actually 64 null bytes
Compatible Programs
