Square Enix just posted four movies showcasing the new content in Chrono Trigger DS (thanks Justin!!). Head to the Japanese site and click on system on the bottom menu to get to the new contents section. In order from top to bottom are clips of the new interface/classic Super Nintendo interface, Dimensional Distortion, Dragon’s Sanctuary (pictured), and Dimensional Arena (monster battling). From the movie it looks like monster fights happen automatically like Final Fantasy IV’s Whyt battles, but with Overlords and Nus.
