Game Data Port

From Liquipedia StarCraft Brood War Wiki

By default, StarCraft uses port 6112 to communicate with other players, and infrequently with the server. This is an issue when two computers in the same network attemp to play in the same match as each other. StarCraft refers to a registry key called Game Data Port to select which port to utilize and if the key is not found, 6112 will be used.

Key Information[edit]

- Value
Location HKCU\Software\Battle.net\Configuration
Name Game Data Port
Type DWORD
  • Note: StarCraft will check for the key in HKCU first, and if it does not exist there, then it will check HKLM.
