We managed to dig this old dedicated server program up but it has a long way to go before its stable in 1.2 im not sure but it might not be the correct version eithor for 1.2
right now its made that it can host and people can join, first person to join can choose map and start game but it gets stuck in gamestate... if someone could tweak this program and make it work maybe we could give bz2 a jolt to 1.2 (and 1.3 like i mention below)
if possible could it also work for 1.3 later on if someone can dissect it?

-edit id recommend not putting this in the 1.2 folder you use
also the basic contents we left in that came with it
