On recent version of wine (0.9.56+) you may experience crashes. To work around this, start the main application like this:
cd /home/jeffz/.wine/drive_c/Program\ Files/LucasArts/Jedi\ Knight\ Demo/
wine jkdemo.exe -windowgui
HOWTO
To stop regressions in this game, a few test cases need to be written
1. reproduce the ddraw codepath used in the cutscenes at the beginning of the game
2. reproduce the ddraw codepath used for the menu system where blitting is done to
update parts of the screen, they are redrawn incorrectly, so a test comparing the
expected colour value against the updated value is needed
3. probably the hardest, would be a testcase that uses the same 3d acceleration as
enabled by the configuration options
