Very nice project!

I have a similar script who uses SWF and XML files. Its development is not finished yet so there are still some errors, but extraction from SWF works fine. If you need help I am available

Here is the thread of my project (on a French board):

@Tsuka: I can send you my avatar imager for the body parts if you want.

I've written a little script to extract data from SWF files.
Maybe it can help you or someone else to understand how SWF files are structured

I also developed process of similar dump program before, but more of your code is light.
I developing extract tool now using it.
