Well you should have a file called atlas.bat in your game folder. Using notepad add to that file : -mod=nameofyourmodYou might need to create a mod.json for it to load correctly. Here is an example { "name": "han_china", "version": "0.0.19", "label": "0 A.D. Han China", "url": "forum.wildfiregames.com", "description": "Adds the Han dynasty of the Chinese civilization to 0 A.D.", "dependencies": ["0ad>=0.0.19"], "type": "content.civilization"} You will not see the dds file, it's cached in your %LOCALAPPDATA% folder.
