Die Hard Trilogy container | Archive storing the game's data files, located in ./data |
Die Hard Trilogy container
Each container begins by indicating the number of files it contains :
| Data type | Description |
|---|---|
| UINT32LE count | Number of files in the container |
Then is followed by count structures :
| Data type | Description |
|---|---|
| UINT32LE offset | Offset in bytes where this file begins in the container |
| BYTE filename[12] | Name of the file (DOS 8.3 style, padded with null-terminated characters) |
Note: the last file name will be null and its offset will equal the container size in bytes.
The logic for extracting files from the container is as follows :
- read the number of files in the container
- read the structures following (named files[] for this example)
- write a for loop running from index 0 to count - 1
- get the beginning offset of the current file from files[index]
- compute file length by subtracting it to offset of files[index + 1]
- and so on until index == count - 1
LOADER
| File name | Description |
|---|---|
| LOAD.MWF | Contains 30 audio samples |
Format of audio samples
Monophonic 8-bit unsigned PCM at 11 025 Hz appended with a 36 bytes structure at the end:
| Data type | Description |
|---|---|
| UINT32LE unknown1 | ! Seems to be always 0 |
| UINT16LE unknown2 | ! Seems to be always 1 |
| UINT16LE unknown3 | ! Seems to be always 1 |
| UINT32LE freq1 | ! Sample rate of this file ? |
| UINT32LE freq2 | ! Sample rate of next file ? |
| BYTE unknown4[8] | ! ??? |
| UINT32LE nextSize | ! Size in bytes of the next file in the container |
| BYTE unknown5[6] | ! ??? |
| UINT16LE eof | ! Seems to be the EOF indicator (systematically 0x5400) |
