I found an XML editor. It's here on this frorum under Empire at War editing > EAW Mods General Workshop > and the topics name. I am not exactly sure what it's name is, but it could be anywhere from page 1 to 6. When I got the XML editor it was on page 3 or 4.
I have found the factons.XML folder so I can edit my population cap, but my computer won't let me edit or delete anything. Do I have to have a certain tool to edit it? Please tell me where to find the tool if it is needed. Thanks.
