I wanted to reverse a NFS U2 a little bit. Even before putting exe to IDA, file server.dll catched my eye.
So instead, I imported this file, and it had only three exported functions StartServer, StopServer and IsServerRunning.
I messed little bit with it, and created absolutely stupid simple executable, which can start this server. You need to have in same folder the server.cfg . Note, that if you host server on same machine as client, client will not see the server. This is something what I will maybe will take look on.
