Multiplayer To get multiplayer working you have to use by now (wine 1.5.27) the directplay libraries from microsoft, still (since 2006) no open source libraries for direct play that include libraries to open sockets and close to play games, so install winetricks:
(in ubuntu/debian) sudo apt-get install winetricks
and then exec: winetricks directplay
It will download the directplay libraries from microsoft and install them, that's all, tcp/ip will work with direct connect.
