@converse: Both scripts and plugins are already supported. Phantom/StrongOD will never be supported though, because they use the ollydbg plugin engine.

@Aguila: Leaving out the GUI, there are a few things that need some work, just tell me if you like something:

  • more (script) commands (eg find eip,#12?3??54#, gmi/gma using TitanEngine for retrieving imagebase etc, etc)
  • commands to dump memory regions/modules (using the Scylla DLL?)
  • working on XEDParse, to support more instructions (would really help a lot)
  • plugin API needs a good look (is there more needed, apart from GUI interaction)
  • TitanEngine bugfixing (would really help a lot, there are many bugs)
  • multi-layered loop definition commands (just like the functions), check out DbgGetLoopTypeAt in the Bridge
  • optimization
  • better roadmap lol
@ahmadmansoor: Yep, we can rock :)

I think that you should delay this to somewhere in the future, because scylla has a nice memory/pe dumper, so it is not really necessary:

  • commands to dump memory regions/modules (using the Scylla DLL?)



TitanEngine bugfixing (would really help a lot, there are many bugs)

How do you know that there are many bugs? And how can we find them?


So it looks like fixing titanengine is still very important.



PS: Don't forget to add a Thread Viewer, I think this is also important.

@Aguila: Why delay? It's useful to have this one your hands when you need it. I know it's in Scylla, but having it as scripting feature is really powerful.

Regarding the bugs: Just read some code (I kinda refactored everything this evening) and you'll see the bugs come out. The main thing needed is testing modules for everything, which is a TERRIBLE lot of work :(

An example of a bug/design flaw: TitanEngine is not thread-safe, memory breakpoints fail, GlobalAPIHandler bugs, x64 is not fully supported, the memory footprint is terrible (need to use vectors instead of static lists), it needs a MemoryRead/MemoryWrite function that covers breakpoint data, stuff like this.

Will add the thread viewer, but it will come together with a better GUI api I guess :)

This debugger is so much better every day. I try to debug a file with IDA and x64_dbg, and now is more more easy with x64_dbg. Any way to locate addresses from one offset address? I try to go in one addres in dll file and don´t know how do it.

@Mr. eXoDia:

One of the best x64 debugger!

Some features to be added:

All Strings from exe (Az):
- please add search a string on them
- please add set breakpoint on the string address
Other features to be added:

- the ability to save changes to file

- the ability to view call stack,

Hoping you will implement at least some of these!


Best regards

@arturo1000: glad you like it! Currently there is no way to get the VA from an offset of RVA, but it is possible to make a plugin that does this. It was added to the todo list.

@CodeCracker: thanks :) String searching has already been implemented, but in the currently release it is buggy (just start typing in the list and it will search). Breakpoint is a really good idea, will add that immediately! Sorting a StdTable (where the strings are stored in) is currently not supported, but it is also on the todo list. Same for saving patches and the callstack :)

@chixiaojie: No, it's not currently possible and it will never be directly supported by x64_dbg. You can however create a plugin that makes changes to the SQLite database. I will add support for this in the bridge.@ChVL: I also found that this happens sometimes, but I cannot reproduce it correctly. I think it has something to do with TitanEngine, but it requires some more testing time.@CodeCracker: Currently I did not implement GUI-friendly stuff (like putting breakpoints in the references and other stuff), but please tell me when you find some more, it is on the ToDo list. I just had many requests for this feature.V1.4ALPHA is out (lol, kinda spamming)Changelog:
- fixed some bugs with references
- added the 'Previous (-)' and 'Next (+)' function (to get back to your previous address of interest). This has a maximum depth of 1024, but it's easy to change this to any other value, since I use dynamic arraysDownload:

Is "Trace" option presented into your TODO list? If no, add it please. :-)


Also thanks for implementing "-" button :)


Also found bug: "Open" windows says it's allowed to choose *.exe AND *.dll. But if you choose .dll debugger says "error starting process (invalid pe?)". Probably it should call something like loaddll.exe...

I have a suggestion, when starting the program on the lower left corner it displays a red "Terminated" text, it should display "Ready" or "Load a file".
