HI!
you know, no each swf file can be to decompilling. and else - are you sure about these files was create in as3 (not as2) ? I have an experience for decompile. But any file need to be try and may be this is not possible. I think you can pay me for each file separately if this will success
Done quickly and efficiently. I'm a newbie on this site, but I have 16 years experience (Adobe Flash IDE, as3(as2), Air, Flash Builder, Adobe Photoshop, etc.).
Please see my portfolio (all works made full by me)
