Hi everyone, Maybe some of you heard it already, but Sigma and I are working on an x32/x64 debugger for Windows for a few months now... The debugger currently has the following features: variables, currently command-based only basic calculations, can be used in the goto window and in the register edit window. Example: var*@401000+(.45^4A) software breakpoints (INT3, LONG INT3, UD2), currently command-only (just type 'bp addr') hardware breakpoints (access, write, execute), also command-only stepping (over, into, out, n instructions), can be done with buttons/shortcuts memory allocation/deallocation inside the debuggee quick…

Hello, I'd like to know if it's possible to programmatically configure the debugger to ignore execptions. What I'd like to achieve is this configuration: I couldn't find any script cmds to configure this aspect of the debugger. Is this even possible? Thanks a lot, Luca

I wanna write a plugin that can retrieve some information of sections of certain module. I can fill the ModuleInfo structure, but the structure doesn't contains sections member. How could I get sections' name, base address of certain module? Thank you! Script::Module::ModuleInfo moduleInfo; Script::Module::InfoFromAddr(modules[i].base, &moduleInfo);

Hi all, I'm trying to use the findall (or better yet, findallmem) command in x64dbg to find all the address matching a pattern. The command is documented here: https://help.x64dbg.com/en/latest/commands/searching/findall.html I see that $result now contains the number of occurences, so the pattern was found (multiple times). Now, this might sound like a silly question (sorry if it is), but how can I actually get the relevant addresses where the pattern was found? 😅 if i use the find command, the relevant address is stored in $result. Where are the addresses stored in the case of findall? Thanks a lot, Luca

I am trying to change the aspect ratio of an older 32-bit game from 4:3 to 16:9. I have already successfully changed the game's resolution to 4k (3840x2160) (hex - 00 0F 70 08) which is stored in the game's save game file (not the executable). However, there's no aspect ratio information stored in this same save game file. Hence, I am looking for it within the game's executable. When searching for AB AA AA 3F (4/3 = 1.3333333) using a hex editor I am able to find one match. Changing it to 39 8E E3 3F (16/9 = 1.7777777) does not change the aspect ratio however. It's because I have found that this one match in the entire executable is actually the game's FOV and not th…

Hello guys. the command `bphws $abc, 'r'` puts a hardware breakpoint on execute. But, what i want to do via command is to `breakpoint > on acces > dword`. You know you can do this right click on **DUMP** window and select `breakpoint > on access > dword`. I have searched: Google x64dbg documentation tuts4you forums Unfortunately i couldn't find a way to do that. Did i miss something? P.S I need this because i am writing a script. Thank you :)

x64dbg plugin in delphi
by remek002- 4 replies

I recently started playing with the Delphi language and decided to create a little x64dbg plugin that will add a calculator and a notepad in x64dbg. Since @quygia128 made x64_dbg-PluginSDK and the CleanupEx plugin, I decided to go with x64_dbg-PluginSDK. Due to the fact that x64_dbg-PluginSDK lacks a few functions, because the last update was in 2014 and for this reason there were some functions missing in the code, e.g. you cannot add icons, menu in disassembly, HexDump etc... I tried to compile the plugin with DELPHI x96dbg Plugins SDK, but the plugin does not work, i.e. x64dbg crashed. Then I decided to update x64_dbg-PluginSDK and add the missing f…
