PaRappa the Rapper DS

Given the basic interface between the Nintendo DS and the original PSX controller is similar, I think that a PaRappa game for the DS wouldn't be much different than for the PlayStation. This is what I think the interface for PaRappa DS would (should?) look like. Basically, the subtitles and visuals would be on the top screen while the vital gameplay data, like the gauges and the note chart, would be on the bottom screen.

X is Triangle
A is Circle
B is X
Y is Square
