Hi,
i have written a troop name editor for anyone interested in this.
Downlaod and Manual are available here.
Hasn't been tested to the n-th degree because i don't get too much time to play. Did test with a few reinforcements and it seemed fine. The problem that people have been encountering with editing the pack.txt file in the LocalizationPack.vfs file is probably due to the fact that the file is UTF-16 encoded (unicode).
My application saves the files back in the correct format. You also have the ability to save your list of names seperately so you don't have to retype them when someone releases a new mod what alters the LocalizationPack. RTFM.
Anyway, standard disclaimer, use at own risk, backup your LocalizationPack file before appying changes etc etc.
Requires MS .NET Framework 2.0 to play. Link available on site.
Enjoy
Snotface.
