OK,
found that file:
All this does is replace the menu.txt. from Russian to English. So the main menu is in English.
As I said before, I had a full "google translation" of the rosters but lost it due to a USB drive crash... When I have the time, I will re-create the roster file.
As to the main game translations, I use the map to find my missions, and as another poster has said, translating into English for non-Russian speakers is such a long process for us.
But then you have to ask yourself, If we have problems, then the SOM Group also have their own problems in translating into English...
Fingers crossed between all of us, this mod will soon be playable for all.
But I have to say.... there's another MOD from mother Russia in town.
