Additional Comments

As installed, extreme graphical glitches make it nearly unplayable. Surfaces are not drawn, or are sometimes drawn in front of surfaces that are further away. Altering the settings in the menus does not help. However, editting the color depth settings in GameData/demo/jk2config.cfg to "seta r_depthbits 32" and "seta r_colorbits 32" reduce the glitches enough so the game is playable.

HowTo / Notes


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

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
