v23.0.1 contains: rulers, grid, guides, snapping, editor for filters (in simple editor view) - add your favorite filters like drop shadow, bevel, glow or their gradient counterparts (edit gradient!). Also adjust color and convolution (with presets). See blog.free-decompiler.com/2025/05/16/new…

@JeanPau68221910 @genord I do not provide any kind of support for your projects, sorry. In the issue tracker, you can report bugs or request features, that's all. You can ask questions there, but I don't want to work on other people projects, sorry.

@JPEXS_FFDec Need help with a project please can you contact me on discord i'd really like to talk to you @genord is my pseudo on discord

A debugger inside our #flash decompiler also displays details of variables. According to Flex SDK, a variable has flags - bitfield. Unfortunately, some flag names are missing. Does anybody know them? Flex says it should be in "splay.h", but it's not available without FP source.

@liamgrist69 It's there from 21.1.0 (but rather later, since the bugfixes).

@JPEXS_FFDec can you add Macromedia Flash 8 For the FLA Export in the next update Please?

@Ralan1180709 It's not possible. However, the syntax is very similar so you may copy parts of the code from asasm. Sorry for answering late.

@JPEXS_FFDec is possible to open a .asasm from rabcdasm with jpexs?

FFDec 22.0.0 contains new Simple editor view similar to Flash Pro / Animate: Easily move objects on stage, edit instance properties, undo command, drag&drop library items to scene, add frames. Also Flash SOL Cookies editor added. See video on the blog: blog.free-decompiler.com/2024/11/10/new…

v21.0.0: Colorized CLI help. ActionScript linkage dialog. ABC cleaner. Export to FlashDevelop and IntelliJ projects. Save all button. Few FLA export enhancements. AS3 debugger for nested SWFs. All news: blog.free-decompiler.com/2024/08/05/new… See the debugging in action: youtube.com/watch?v=HCHMsi…

I don't necessarily need the meaning, the flag names would be enough. I just want to display it in the debugger UI, instead of "unk512". Could somebody from @Adobe help or I dare too much? It's just a small enumeration of constants...

In FFDec 19.0.0 we've got new ABC Explorer for display ActionScript internals. (I can't hide I took inspiration from @ASVGuy, hope he won't mind). Also Embed tag assets export, compound scripts as separate trees, export DefineFont4, API versioned ABCs. See blog.free-decompiler.com/2023/10/01/new…

@Apocalyman Exporting as EXE requires ActiveX component installed. This is problem because current operating systems disallow that. You can export as EXE projector - see advanced settings / Export / EXE export mode. For more info/talk visit our issue tracker.

@JPEXS_FFDec Hello I wondered if you could help me. I put in a SWF and tried exporting it as an EXE and it gives me a "class not registered" error with another one following it. Do you know how to fix this perhaps? (I have all DLLs downloaded)

Couple of days ago we released the version 18.4.0 . Now we got a new blog! We might post some info about SWF file format internals there. Also there's category with FFDec news that describes the new features since 18.x (with screenshots and comments) See blog.free-decompiler.com/category/ffdec…

Version 16.0.0 released. New "Tag list view" shows how tags are really ordered. You can now add new tags at specific position, move tag, clone tags or add new empty frames easily. Context menu icons. Also many bugfixes. github.com/jindrapetrik/j…

@Rindai_MnF For AS1/2: yes, via context menu on scripts folder. For AS3: the same way via menu you add class, then you need to assign class to sprite via SymbolClass tag.

@JPEXS_FFDec Hey is there a way to add scripts to newly created sprites?

Version 15.0.0 released. Direct editing Actionscript 1/2 is no longer marked as experimental. We fixed many related bugs and we think it is pretty usable now. AS3 is still not working well... #as1 #as2 #actionscript #flash #editor github.com/jindrapetrik/j…

@Puzzlecube3 Sorry, preffered way to contact us for problems solving is our issue tracker ( free-decompiler.com/flash/issues/ ), please use that. We do not check twitter too often. Also, support is still very limited.

@JPEXS_FFDec I've been having issues with exportAsset. Is there a solution or will a bugfix come any time soon? I'm working with a flash game that uses names for gun animations which are then spawned via script. I can only seem to use sprites which were named to begin with.

Version 14.0.0 now - Adding new scripts or classes, remove existing. History of script search, scoped search or search across SWFs. PDF export now with selectable text. Also contains many bugfixes! And what do you do when locked at home? #flash #decompiler github.com/jindrapetrik/j…

Anyone still interested in #flash ? We released FFDec version 13.0.0. Many AS3 decompilation related bugs fixed. New: P-code format more close to RABCDasm. Display / editation of body traits. Graphviz graphs colorized. Download at github.com/jindrapetrik/j…

@Ledtech3 I guess people will still want to export some sprites from older SWFs after flash is gone from browsers. As stated in the issue tracker - we do not work on the decompiler anymore. This was just "make current old nightly a release" and a little step "support Java9+ in someway".

@JPEXS_FFDec How much Longer is this going to be supported since flash is "supposed to be going away" ?

New version 11.3.0 was released with features from previous (not-so-often updated) nightly version (Java8). Also new nightly with Java9+ support released with some REMOVED😟 features. See changelog on github for details. github.com/jindrapetrik/j…
