This version offered the ability to import edit data from the previous game, Dance Dance Revolution Konamix, into this game's edit library. This means that if you had created a custom step chart for a song that both games share, you could import it directly. You could also export edit data from the library and share it with previous games in the series.

Future games released on the PS2 would retain this feature.
