Very nice job. You're basically one of the only ones who really try to go above the limits of the 3DS and figure out alternative ways to do certain things.
its a paint app for my website.
anyway i really wish the 3ds knew toDataURL() though. i tried alternate things all day and now i have no choice but to send parts of the picture 1 by 1 to save it. and then i have to make php create the image. but after that i just have this layer switching glitch left then i will be finished.
