This Guide Was Meant With The Ultimate Mod In Mind...
Other Mods Might use a Config.Meg File, if thats the case just drop it in Gamedata\Data directory. But this method is for XML files.
HOW TO INSTALL!
You need the FOLLOWING Program to Be Able To Open The File You Downloaded.
Now, When You Open You're File it should be like this...
Click Extract... and you get this. Make sure the options are exactly like mine. Also Make Sure The Address is Correct
Now this should be what you see inside you're GameData\Data Folder.
And Youre Done!
