Selected Test Results

What works

Normal single player, saving and loading, menus, configuration, etc. Played through until the end of the single level.

What does not

Multiplayer. It pops up a screen with an empty selection of "network providers". Trying more than one 16bpp mode fails. It then tries to switch back to the previous mode. If this is also a 16bpp mode (i.e. there wasn't an intervening 8bpp mode), it fails, and may return to the menu, or may crash.


What was not tested

Joystick usage.

Hardware tested


  • GPU:
  • Driver:

Additional Comments

The -windowgui option that appears necessary for the full version is not required for the demo.

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
