Expendable, a arcade shooter that comes with it is mindless fun, I remember playing it on the Dreamcast, but having two sticks makes the game more enjoyable.

Drastic is a good DS emulator, but it doesn't support resume previous game so that kind of sucks.
Both mine have had amazing battery life, but one does get warmer than the other. Actually, my replacement one doesn't get warm.
