The game trackballs is outdated in the repository. The site is http://trackballs.sourceforge.net/ , and the direct source download link is http://prdownloads.sourceforge.net/trackballs/trackballs-1.1.0.tar.gz?download
If someone could add this new version I'd appreciate it. It has some large bug fixes. I tried compiling it myself, but I just got errors.
If this isn't the right place to post this, let me know where the correct place would be.
