r476 came out and a new feature came with it ;) 

This is what gianpune said at the changelog:

Added support to read game information from xml.  The first draft of the xml is
in the downloads section of googlecode.  Put the file (still zipped) in your
titles.txt path.  then highlite a game and press 2 to view stuff about the game.
If a synopsis exists for that game in the file, you can see it by pressing a.
Currently only 1 game has a synopsis.

There are lots of fields that are wrong/missing on the xml but don't tell us
about it.  Somebody else (Lustar) will be in charge of keeping up with it.
