I recently installed homecoming coh on my new computer. I used this app to install the vidiotmaps change. When I tried to run Coh I received the following error:
c:/Games/Homecoming/assets/modes/hc_vidiotmaps.pigg: Fileheader extends past end of .pigg, probably corrupt .pigg file! #74
The archery mod works fine, so it seems to be the .pigg file.
