Speaking from experience as a programmer trying to make a Nanoha-based fighter, there are an insane number of frames. I began using three dimensional models, then using gif-rips of the animation. Even on the highest picture compression, Flash took at least ten minutes to compile. Needless to say, it was impossible to work with. I'm redoing the entire engine, using maybe two or three frames per animation, hand-drawn into vectors, and it's still taking forever. Given, I'm no artist, but it's still tough enough to realize that the crazy guys ((and hopefully girls)) at French Bread deserve more respect than they receive.
