This script adds a new PvPGN server in the Windows registry without removing existing servers. As a server owner you can setup the script by once and then distribute it to your players.
Setup is pretty simple - just open the BAT file with any text editor and edit several variables:
:: server connection
set title=Your Server Name
set address=127.0.0.1
set timezone=1
:: games to setup in the registry (true or false)
set starcraft=true
set warcraft3=true
set diablo2=true
Then rename file to install {SERVERNAME} gateway.bat. For example, install iccup gateway.bat
