Written by tox:
hey folks,
ever wanted to edit the savegames of Dune? Well, I wanted to, but I couldn't find any editor... obviously no-one ever made one because the game uses an unusual compression method for the gamedata including the savegames. After a lot of research I found out how it works and made an editor for it. The classes I used follow. Mind you, even though I did a lot of testing I can't guarantee it's bug-free. Have fun and let me know if you do something with this.
Have fun!
