To get the WAC file to work you must edit your BHD shortcut target.

to do this,

create and new BHD shortcut (or edit your current one)

right click on the shortcut >> go to properties>> target

"C:\Program Files\NovaLogic\Delta Force Black Hawk Down\DFBHD.EXE" 

		^^this is the default target^^

change to:

"C:\Program Files\NovaLogic\Delta Force Black Hawk Down\DFBHD.EXE" /d


Then apply the changes and place the WAC file in your BHD directory folder
