From what I understand, most homebrew programming on the DS is done in C or C++, and the source for PD is in C, so how much work would be required to make a port? It seems the stylus would be good for connecting objects, and the buttons could each make a different kind of object box, and the d-pad could be used for navigation.
If anybody is interested in working on this with me, let me know!
Thanks,
Chris
