I'm sorry that I can't help, but you're planning on doing some animation, huh? Nice!

You draw on DS so why not trying Flipnote? =3

flipnote is not on the 3DS

Oh, and I thought they would have made it available for it as DSi Ware download. Hmm...
Oh, what about Inchworm Animation? Looks like a good program to me. =3

what do you think i've been using xD

I thought of a flashcard program at first because I don't know any other animating software than Flipnote. <=///3

at first yes the flashcard thing then i bought inchworm animations. animating is confusing.

Can't you just use that onion method that shows every last frame in transparency so you can draw the next frame right above it? Every animation needs the thought of what every scene shall show and then you need to draw the scenes. It's not that complicated I think but it is loads of work. =3
