1. Go to This Directory
{If your on windows of course

}
c:\documents and settings\YOU\local setttings\Application Data\Tremulous
2. Create a new folder in there and call it: Arcade
3. In your new arcade folder put all the files that you need for a arcade mod.
4. join a arcade server and enjoy.
If ur still a noob and cant figure it out:
1. Start Tremulous
2. Go into the options menu and turn autodownload on
3. Join a arcade server and it will automatically download the mod for you in the right spots.
Warning This might take a long time depending on the server and ur internet connection
That should fix your problem.
For your server:
change this code in your command line:
tremded.exe +set dedicated 2 +exec server.cfg
to:
tremded.exe +set dedicated 2 +set fs_game arcade +exec server.cfg
That should work but i wouldn't know because ive never tried to host a arcade server.
With the patch files dont try anything with them ur to mutch of a noob!
but they are basicly just files that you apply to the tremulous sorce code witch change it into a sorce code for a mod or new server side cmd.
One more thing. Copy your arcade game.qvm into the
arcade directory u allready made.
Make sure u put it in a vm folder 2
