SoThink Swf Decompiler.
Sothink SWF Decompiler is a tool to browse, play, and parse Shockwave Flash movies. Sothink SWF Decompiler, which is compatible with Flash 8 and ActionScript 2.0 completely, can export all elements in various formats and convert SWF to FLA. Exporting FLA settings are available. To more considerate design, SWF Catcher on the IE and Firefox toolbar can catch the Flash movie directly.
You can use this on swf files inside mycoke for instance.
