Editing ActionScript

Editing ActionScript
  • Displaying ActionScript code on the left, p-code on the right
  • Clicking AS item hilights position in p-code and vice-versa
  • Editing existing actions P-code, direct ActionScript editing
    • Editing AS directly is experimental and some features may not work yet.
  • Optional editing AS3 scripts through Flex SDK (unstable)
  • AS3 P-code: Syntax is based on RABCDasm. See its homepage for details.
    • constant pool is updated automatically
    • popup documentation for each instruction and code part (AS3 only)
    • now with editing metadata
  • AS3: Find multiname declaration with Ctrl+click (Local register, types, etc. too)
  • AS3: Find multiname usages (Ctrl+U)
  • AS1/2: Ctrl+click - Go to declaration of variables, registers
  • Easy editing obfuscated names with paragraph syntax (§ while§, §in+v-%§)
  • Easy editing colliding names with hash syntax (item#1)
  • Special instructions to handle unstructured code (§§pop(), §§push(x))


Builtin proxy
  • Search text in ActionScript source or text tags (can use regular expression)
  • Search by all P-code files (AS1/2 only)
  • Go to Document class (AS3)
  • Proxy
    • Configure your browser to use our proxy
    • Proxy sniffs http communication and searches for SWF files
    • Found SWF files can be edited in place and then served via proxy again
  • Search memory
    • Search SWFs in other processes memory
  • Search browser cache
    • Search SWFs in web browser cache
    • Supported browsers: Mozilla Firefox, Google Chrome/Chromium
    • (removed in 7.x, not updated for newer browser cache formats)
  • Deobfuscation
    • AS3 P-code deobfuscation (Few technics to remove dead code inserted by obfuscators)
    • Globally rename identifier
    • Rename invalid identifiers (Obfuscators often use wrong characters in identifiers)
    • Rename colliding identifiers (Obfuscators use same names for methods, only with different namespace)
  • Time line view
    • Display timeline of objects placed in the frames. See object location in the preview window.


  • Automatic deobfuscation
    • Application can automatically remove dead code and other obfuscated code. This is off by default as it can break decompilation of regular files.
  • Simplify Expressions
    • Complex (often obfuscated) expressions are simplified to (usually)one value to make code more clear
  • Use Own flash Viewer
    • On windows platform, internal Flash viewer can be used so flash content can be displayed without Adobe Flash Player. On other platforms, internal viewer is on by default.
  • Parallel SpeedUp
    • Application can use parallel approach (threads) for reading SWF/decompilation to be faster
  • Disable decompilation
    • AS decompilation can be disabled so only P-code is visible. This can be used if decompilation takes much time for example.
  • Add FFDec to SWF files context menu
    • On windows platform, this can add "Open with FFDec" right click context menu to windows explorer
  • Highlight document class on startup
    • FFDec can jump directly to AS3 document class after SWF opening
  • Auto rename identifiers
    • On SWF opening, automatically execute "rename invalid identifiers" operation
  • Open loaded SWFs while playing
    • If you run SWF with Run command in the menu or display in FlashPlayer in the FFDec, all SWFs which are loaded inside ActionScript while run will be then opened in FFDec. This applies to encrypted SWFs loaded from DefineBinaryData tags too. Useful for any kind of AS3 loader.
  • Change language
  • Advanced configuration for experts
Settings panel


  • Displaying tags coming from imported assets
  • Removing tags via right click context menu in tag tree
  • Move or copy tag to another SWF
