I don't know if the second DWORD value is zero in ALL games and ALL versions. I do know that it is hard-coded in the current version of Starcraft: Broodwar, though.

Missing 0x80 state bitwise flag. It means a replay game.
Also, the provider version constant (Gotten from storm network provider information structure +0x28) may not be 0xFF in all games and all version. It is 0xFF in the current version of Starcraft: Broodwar, however.
