Updating World of Kung Fu is a bit tricky. First, you'll need to find the manual patch site, which tends to hide.
Go to http://www.worldofkungfu.com/index.cfm?src=&action=manualpatchmirror .
Second, download the manual patches.
Third, start up Crossover Games.
Fourth , use "Run Command", in the Programs menu, to run the patch. When the patch asks you what to update, be sure to go find the folder with all the program files in it.
You'll get a bunch of control characters instead of what the windows are supposed to say and the update window will stick to your cursor until you exit Crossover, but it will update!
