Answer 1

Technically you can use a decompiler to do this job.

There are free (e.g.: ActionScript Extractor) and paid (e.g.: Sothink SWF Decompiler) tools out there.

But, before you do any decompiling processes, note that you MUST have permission from the author to see (use or anything else) his code.

I'm not a legal authority here, so what I say MUST NOT be used as truth.
And, you may be charged legally if you break an copyright law or something!
