Known Bugs

Known bugs in current Dune Legacy (0.94.1)

Playing as Ordos doesn't work. Period. (The map seed files aren't in the datafile set, and without an extractor, it just doesn't work.)
Map data (both units and terrain) varies dramatically from the actual Dune 2 maps (Atredes and Harkonnen Map 1, where you get one of every unit in the game or slaughtered mercilessly by numerous Atredes troops, respectively, are great demonstrations of this)
Load Game/Save Game don't work(they do now in svn revision 44).
Multiplayer dialog breaks when changing resolutions
Carryalls fly under buildings, rather than over them.
The minimap does not rescale depending on the size of the map, so maps often fill a subset of the minimap, leaving the rest unclickable.
Multiplayer so far it's not possible to find game servers automatically. So in order to play with your friends you have to edit dunelegacy.cfg and set line 6 to server's ip or hostname: e.g. a computer that is server is "dunelegacy" (under linux you can check your hostname by executing "hostname" in terminal), set line 6 to dunelegacy and enjoy multiplayer
