Is it the game file or is it my R4?

I've tried playing Chrono Trigger DS. I can get up until the point where Marle gets teleported to god knows where and crono follows. After he gets sucked into the portal thing, it just loops the music and the trippy hyperspace looking wormhole.What the flying f**k. What is causing this and how do I fix it?
