thank you for the answers !
I have no patience to try your method for map swapping with the mission editor LOL
ufo :-)
No problem. I've managed to add the Armored Fist 2 demo map to the mission editor.

You just have to extract the pcx files from Armored fist 2 and import them into comanche golds resource.pff.
Delta Force 1 Maps crashes the mission editor.
