Flash 9 Decompiler with source

click here to download zip file containing command line flash 9 decompiler

unzip the file to decompile your flash 9 swf using this command prompt tool

copy the abcdump.exe to your local folder then place swf file too on the same folder then you are ready to decompile ex: c:\abcdump.exe <swffile>.swf

An open source decompiler link

  1. Example :
    RawAmfService class below after compilation

    public class RawAmfService extends EventDispatcher
    public var gatewayUrl:String = “”;
    var loader:URLLoader;

    public function RawAmfService()
    loader = new URLLoader();
    loader.addEventListener(’complete’, readData);


    And the decompiled class looks like:

    class RawAmfService extends flash.events::EventDispatcher
    var gatewayUrl:String = “” /* slot_id 0 */
    var loader:flash.net::URLLoader /* slot_id 0 */

    function RawAmfService():* /* disp_id -1*/
    // local_count=1 max_scope=1 max_stack=3 code_len=40
    0 getlocal0
    1 pushscope
    2 findproperty gatewayUrl
    5 pushstring “”
    7 initproperty gatewayUrl
    10 getlocal0
    11 constructsuper (0)
    13 findproperty loader
    16 findpropstrict flash.net::URLLoader
    19 constructprop flash.net::URLLoader (0)
    23 initproperty loader
    26 getlex loader
    29 pushstring “complete”
    32 getlex readData
    35 callpropvoid addEventListener (2)
    39 returnvoid

    Is it going to be true decompiler, and will decompile function body as well in future?

  3. No, myself waiting for a proper decompiler. But, I am sure that the decompiler(of future) will give output in form of AS3 with lot of mx components (hard to read)
