So now that coloring is supported I made x64dbg look like my olly so I finally feel "at home". (Also because all other features I missed are now mostly supported) Theme is derived from the original Olly scheme by "Patrick from France", his original quote about it you can add it by replacing the [Colors] section in the .ini with the following [Colors] AbstractTableViewBackgroundColor=#000000 AbstractTableViewHeaderTextColor=#000000 AbstractTableViewSelectionColor=#000080 AbstractTableViewSeparatorColor=#0000FF AbstractTableViewTextColor=#FFFBF0 DisassemblyAddressBackgroundColor=#XXXXXX DisassemblyAddressColor=#808080 DisassemblyBackgro…

Hello everyone, im new her and do have a question. I did debug an executable and changed some code. When im trying to save the file an error pops up that the module name couldnt be read. Does anyone know why this is happening? I can send the file if someone wants to look at it. It seems to me that the changes I want to write are not in the executable but maybe in memory. Attached is the String im changing. I just want to noop the jmp command.

Hi, I'm writing a simple script to search the OEP of MPRESS, something very basic. but not if I'm doing some wrong command, or a bug.

Hey everyone, Because I personally don't have so much time as before I set up a service that automatically builds snapshots from the x64_dbg master branch. If you find a bug, please also verify that it's still in the snapshot. The snapshots are generally considered stable, but you should not them for plugin development.

x64_dbg Screen Recordings
by mrexodia- 2 replies
- 6.4k views
Hey everyone, We would appreciate screen recordings that show you working with x64dbg to see about the usability of the software (or features people generally don't know about). These recordings will be kept confidential if desired. I think they would really help us to figure out what is needed most for x64dbg in the future. Recently I saw Reaver from teknogods working live with x64dbg and I immediately found some things that needed fixing. Feel free to PM your recordings to me or post them publicly in this forum. Greetings, Mr. eXoDia

Process terminates on attach
by Schnappi- 8 replies
- 16k views
Hello,I have stumbled on application I would like to debug. Since it's 64-bit app the OllyDbg is already out of the picture, so I thought I could use x64_dbg. When I try to attach to that process it starts loading all modules and then I get "Terminated: debugging stopped". I tried to play around with ScyllaHide to the point I enabled all options -> didn't help at all. Tried TitanHide -> nope. I also tried to suspend the process first, but it still terminates on attach.It also shows weird behavior when using Cheat Engine's debugger -> when I set breakpoint the application crashes with single-step or maybe breakpoint exception ( don't remember, but I can eventually…

Testing x64_dbg UNICODE support...
by mrexodia- 8 replies
- 10.1k views
Hello everyone, Recently there have been some questions regarding UNICODE support in x64_dbg. If you're a Chinese/Russian/Vietnamese/Japanese/Whatever user, please try this test version on your computer and report any bugs on http://issues.x64dbg.com or in this topic. Everything inside x64_dbg should have UNICODE support. Comments/variables/scripts etc are all supported (hopefully). Notice that your script files should be encoded UTF-8 without BOM. Notice that this is not an official release. This is a branch called 'utf8_support', if it turns out to be working good, there will be a new release. Attached the test build. Greetings, Mr. eXoDia dev22g.r…
