I update the codes for all my games once every half a year. If I don't do this, the code will expire after 6 months and you won't be able to play the game using the codes posted on this page. In case I forget or fail to update the codes, you can find the source code for all my maps here
Just open the document with the desired map, copy everything with Ctrl+A , Ctrl+C and press the small yellow Import Settings
button in the custom game settings window.
Peace to all of you!
