(UINT8) ID (0x4A)
(UINT16) Map Tileset
(UINT16) Map Width
(UINT16) Map Height
(UINT8[12]) OWNR
(UINT8[12]) SIDE
(UINT8[12]) OWNR Default
(UINT8[4]) FORC Flag


Packet CLS 1.

The tileset, width and height are not retrieved from the map in case it hasn't been downloaded yet-- these 3 values are used on failth. Valid tilesets: 0x00 = Badlands 0x01 = Space Platform 0x02 = Installation 0x03 = Ashworld 0x04 = Jungle 0x05 = Desert 0x06 = Arctic 0x07 = Twilight

The OWNR values are the base room slot values. They are modified values from the map to fit the given game configuration. The OWNR default is simply that, the default values from the map file. The 12 bytes is for each possible player (1 to 12) Possible values: 0x00 = Doesn't exist 0x02 = Human 0x03 = Rescuable 0x05 = Computer 0x06 = Open 0x07 = Neutral 0x08 = Closed Note: OWNR of Rescuable and Neutral are not shown.

The SIDE tells you the race for each player. These are modified SIDE values from the map file, to fit the given game configuration. 1 SIDE byte for each possible player (1 to 12) Possible values: 0x00 = Zerg 0x01 = Terran 0x02 = Protoss 0x03 = Independent 0x04 = Neutral 0x06 = Random

The FORC tells you the force/team index of each player. For example, 0x00 would mean no team (like melee) and 0x01 to 0x04 means this player/slot belongs to this team.

The FORC Flag gives you the settings for each force. 0x01 = Random start locations 0x02 = Allies 0x04 = Allie victory 0x08 = Shared Vision

The RACE tells you if a player can change their race I think. I'm not to sure about the RACE part, but i'm pretty sure thats what it does. For example, disables a player from changing their race
