I haven't tried yet because for some stupid reason my IDM refuses to resume the download from Dropbox link. I'm not sure what's more than using existing methods for fixing (dgVoodoo/nglide for the graphics/resolution, CPUGrabber for FPS bug fix, and this patch for multiplayer:
http://peelar.myweb.cs.uwindsor.ca/) but according to the information:
Currently there is an update that allows for more modern resolutions, framerate lock (which fixes a lot of the issues like wheel wobble and mortar distance), and most importantly, adds uPNP to the networking, which allows for multiplayer games through modern firewalls.
