OpenXcom requires original UFO: Enemy Unknown / X-Com: UFO Defense
data files. Please copy all subfolders from original game into
%%DATADIR%%/data directory.

Also note that if you get messages like "GMDEFENT NOT FOUND" or
"INVALID CHRYS.PCK", you need to patch your UFO date to the latest
version. See section `Data Patch' of

  http://openxcom.org/index.php/downloads-extras/

for details.
