There is a new version of Charred Dirt out as of last month.[snapback]3016[/snapback]
Well, it most certainly has been a while since that post. ShadowFang is still at the University of Arizona, and so there have been no new official releases.
However, we did manage to pry the source code from his cold, dead fingers. And so I've managed to build a new subversion, "0.99d", which has working multiplayer among other small fixes. The only problem with it is that you need to patch Windows to make it go, thanks to some odd decision from Microsoft about which updates to install and which to not install.
Visit this post (http://www.charreddirt.com/forum/viewtopic.php?p=23705#23705) in the Charred Dirt Forums to get the updated files, which must be extracted over an existing Charred Dirt installation. Visit this thread (http://www.charreddirt.com/forum/viewtopic.php?t=1271) to see what I've done.
B) Uh, uh, uh, uh, stayin' alive, stayin' alive!
