Greetings!
Mega Man 8-bit Deathmatch V5B is currently using a beta build of Zandronum (the engine MM8BDM uses). We have ensured the beta build is stable enough for V5B's release, although there may be some remaining non-gamebreaking bugs left. Feel free to report anything you find in the bugs forum (http://cutstuff.net/forum/index.php?board=25.0)!
When you download MM8BDM from Cutstuff.net (this page (http://cutstuff.net/mm8bdm/?page_id=5)), it will always be packaged with the latest version of the Zandronum beta. If a new one is released but you have MM8BDM V5B already, you can find the latest Zandronum beta from here under Development Builds (http://zandronum.com/download). You should download this and extract it to your MM8BDM folder if you are getting incorrect version errors when connecting to servers.
TSPG (the service hosting most played MM8BDM servers) are now forcefully running a beta version of Zandronum. You can find instructions on how to join these servers via Doomseeker below.

Check "Testing Releases" and set a directory to store them (your mm8bdm folder is a good location). Now when you try to join a server running the beta, you will be prompted to download the beta. After doing so you should be able to join any server running the beta. You skins folder will not be copied across so you may have to do that manually.
Please post here if you have any questions regarding Zandronum 3.0 and MM8BDM!
