I absolutely love this. I broke my D-3 before I was every really able to play with it, so this is such a treat.
I think they only thing I'd like to see is an option to change the interface between the current device design and a design that adapts the D-3 design to more fit a phone's rectangular display. Like the phone digivice from the Kizuna movies. I hope that made sense >.<
Regardless, thank you for making this, it's incredible.
