Hi,
You´re using suse which has wine package, but i think
you have already installed it.
Look at
http://www.winehq.com/, good documentation
to use wine is very easy, just go to the shell and type wine
followed by the windows executable you want to install
or execute. If you installed wine as a user, the configuration
files of wine located in ~/.wine just modify them to your needs.
There´s a commercial variant of wine called cedega, with this
a lot of win games can run under linux. This prog is also
available as source code called winex, you can get it from cvs.
by the way directconnect client is also ported to linux.
hope this will help you
