Just in case that you are bored by the original start counter. Here is a replacement image.
1.Goto TMUF installation Folder, and to the subfolder:
Programfiles -> \TmUnitedForever\GameData\MenuForever\Media\Texture\Image
2.Make a backup of the original 321Go.dds, just in case you want to have it back!
3.Drag and drop the new 321Go.dds
Can't tell if you need the original for online use.
So fare, no problems with exchanging images.
