The DSi category of the ESRB's database is currently pretty small, containing only eight games, including some of the current first-party DSiWare (not all of the existing games are visible yet), a few Gameloft games (Brain Challenge, Real Soccer 2009, American Popstar Road to Celebrity), and ... three Atari games. Specifically, Ghostbusters, N+, and The Chase: Felix Meets Felicity, all of which are now listed as both DS and DSi games.
