x64dbg VS Kaitai Struct

I have never heard anyone say anything good about the Visual Studio debugger before. Now, I'm not a Windows person but I'm not gonna argue for gdb or lldb here. RemedyBG and x64dbg are the two debuggers I've heard good things about though I've never used them because, again, not a Windows person.

I'd help you out but because of circumstances I have no laptop with me. You need x86/x64 debugger to do this. This one for example Find a registration procedure and look for possible brenching to other parts of code in assembly. It's probably somewhere in the beginning. Exclude code validation and export new program version.

One interesting thing you can do is download an app like https://x64dbg.com/ or cheat engine, which will let you see the memory. You can look at the process for something you’ve made and explore it. Log a memory address from your app then go find it in the tool and interpret the bytes as an integer. Find a string and see how that works. Find a pointer, read the address it’s pointing then go look at that address. You start to see how different containers store data. I find it fascinating.

If you want to also do dynamic analysis (debugging) you can use https://x64dbg.com.

close origin and download this debugger https://github.com/x64dbg/x64dbg/releases

.exe is a complex format and not something you're going to extract raw instructions from using a hexdump. What you need is a "disassembler". For Windows I'd recommend x64dbg.

Patch the DayZServer_x64.exe, change "test al, al" to "cmp al, 2". i used x64dbg (https://x64dbg.com) a good video for the whole process: https://drive.google.com/file/d/1F1A0lpumREPXtVeoTMq1HiEnvaZp-NUU/view

- ImHex [2], which has a pattern language [3] which allows parsing, and it seems more powerful than what Kaitai offers. I stumbled upon some limitations with it but it was still useful.

Beautiful. Didn't know something like this exists. Reminds me of Katai[0]

An EDID override like this would be helpful for macOS as well, where the monitors swapping around after standby is a real annoyance [0] [1]

EDID rewrites are 99% of the time blocked by the monitor firmware: https://notes.alinpanaitiu.com/Decoding-monitor-EDID-on-macO...

By the way, one helpful tool that helped me navigate the EDID dump was Kaitai Struct [2]. It shows a side by side view with the hex view and the EDID structure, and it highlights the hex values in real time as you navigate the structure. Unfortunately [3] it doesn't support the extension blocks that the author needs.

Kaitai Struct might be a good choice for that: https://kaitai.io/

For binary log format, there's the excellent Kaitai Struct frameworks, that make it very easy to generate parsers from a declarative schema

Worth a look if you are writing binary parsers.
