Multiplayer Unit Roster

[schlappi]

Hi,
anyone can help me to alter the file which controls the unit roster on multiplayer? Unfortunately the romani are lacking the polybian principe and the camillan equites, KH has no armoured skirmishers and so on.
Thanks,
schlappi

Edit: Ooops, this was supposed to be posted in technical help forum sorry.

P.S. if i change the files, all my opponents in battle have to change the same files as well to avoid desync?
