Kazan: just make sure to set MULTI_SG_NUM_BUTTONS to 10 and renumber the other button #define's after MSG_OPEN_GAME by -2 (commenting out MSG_CLOSED_GAME, MSG_RESTRICTED_GAME).  Comment out the, at least two each, code blocks for MSG_CLOSED_GAME and MSG_RESTRICTED_GAME that show up later in the file.  This will get rid of the extra (non-visible) buttons and hot spots so that the highlights will be right again.
The bad thing is that I know to do all of that from memory.  I think I've played with the interface code a bit too much since all of it seems completely normal and good to me now.  Think I should seek professional help?
