MDT files are similar to PZZ files, with a header of 0x800 / 2048 bytes including :
- the number of files (uint32 big endian)
- the file size / 0x800 for each file
It is possible to unpack and repack .mdt files with the pzztool.py tool. Unlike pzz, the internal files of .mdt are packaged and not compressed.
- 000 dat file contains at first sight all texts of the game (Related to all dat file, not only one).
- 001 TPL including an alphanumeric alphabet used by the dat file
dat file header:
- 4 bytes - header_length
- 4 bytes - symbols_count # number of symbols contained in the tpl
- 2 bytes - symbols id (array)
Virtual World RE has developed the python script pzztool.py to manipulate MDT files and their internal files.
PGCD of MDT file sizes: 2048 / 0x800
