is that it? have I done it correctly? and how will I know if the new units are in? Do I need to put the 'ATinf.flatdata' and 'ATsounds.flatdata' files into the GT:OS game files or something?
If it shows in your updater then it should be in your game.
Open up a quick battle, look at your top most German infantry division(02/41-mid 42).
For the inf. and Eng. platoons you will notice a lot of new team sized units have been added under support units.
(mainly for the German side).
I put all mods in their own folder and label and date it then put the folder in the game folder.
You can make a new folder in your game folder called mods and put it there.
I have a mod and patch folder in my game folder.
Remember- this is a mod to the uniform mod and must go over the uniform mod in the updater, if you don't have the uniform mod then this will not work.
This is an addition to the uniform mod.Also, the uniform mod usually has to be updated with each new patch-I don't believe the uniform mod has been updated yet for the May14 patch.
This is usually a reason I do not add new patches to my game until the uniform mod has been updated for latest patch.
