Alright, first you need to add yourself to the games group. If you're using Dropline using users-admin makes this easy. Otherwise, search around here for CLI commands to do that. Next, you'll need to change the games' folders to group 'games' and give that group write access.
chgrp games /usr/games/ut2003/ -R
chmod g+w /usr/games/ut2003/ -R
The second command you might want to do to only the files you need to in the games' folders. I put the above down for the sake of length.
Next, you'll need to change the permissions of /dev/dsp, which is most likely a link to /dev/dsp0.
chmod 666 /dev/dsp0
Now you should be able to save games and configurations, and get sound. If only all games on Linux just stored configurations in $HOME. sigh
