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
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
