This section is currently being written.

More research is needed and some paragraphs may be wrong.

MDT files are similar to PZZ files, with a header of 0x800 / 2048 bytes including :

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 - block 1 offset
4 bytes - symbols_count # number of symbols contained in the tpl
2 bytes - offsets for each symbol - in the file relative to after the header (array)

dat file block 1:

4 bytes - array of signed int16 offsets absolute terminated by -1 (FF FF FF FF) The first offset is the block 2 offset

dat file block 2:

dat file block 3:

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
