It takes a while for them to decorate their house. You don't need to delete your file but
here's how anyway:
1.Turn on the ds
2. While it's loading, press a, b, x, y, l, and r all at the same time.
3. you should a note that says "are u sure u want to delete ur file?"
4. if not, you didn't press them all at the same time
5.keep trying until u see da note
