# x64dbg

{% hint style="warning" %}
The GitBook based NorthstarWiki has been replaced in favour of the [NorthstarDocs](https://docs.northstar.tf/) where this wiki has been integrated.

Check it out here: <https://docs.northstar.tf/Wiki/>

The same page on the new wiki should be located here: <https://docs.northstar.tf/Wiki/development/debugging/x64dbg>
{% endhint %}

{% hint style="warning" %}
If you are not experienced with x64dbg it its recommended to use [Visual Studio](/r2northstar-wiki/modding-and-development/development/debugging/visualstudio.md).
{% endhint %}

## Windows

* Download [x64dbg](https://x64dbg.com/)
* Extract the `release` folder somewhere on your PC
* Download the latest relase of [SycllaHide](https://github.com/x64dbg/ScyllaHide/releases/latest)
* Merge the contents of the `x64dbg` folder into the previously extracted `release` folder
* Run `x96dbg.exe`
  * You may receive a Windows SmartScreen prompt, x64dbg snapshots are not signed and will always cause these prompts
  * When running for the first time it will ask you some questions. After this is complete rerun the executable.
* Select `x64dbg` in the Launcher\
  ![](/files/LceGAEBe1qQceuYVoH2I)
* Do make debugging easier it is suggested to change your settings to the following:
  * Keeping System Breakpoint enabled is optional but useful\
    ![](/files/GeNxEkvHf7LiiNttAXJN)
  * Skipping INT3 stepping is recommended to prevent generic breakpoints from stopping the program\
    ![](/files/S5L6RIZobrG6e25GrKy1)
  * Make sure to select the exception before disabling breaking. If you are debugging a C++ Exception you need to ignore common exceptions that occur during runtime\
    ![](/files/p5iOTUfAPnH9Fvdyak6M)
* Open `NorthstarLauncher.exe` in x64dbg
* You are now free to debug Northstar

## Linux

{% hint style="warning" %}
Debugging Northstar under Linux is not trivial due to the direct dependency on Origin, unless you know your way around wine its recommended to debug on Windows.
{% endhint %}

To simplify the use of x64dbg and automate running Origin a community member has created a script: [ns-linux-dbg](https://github.com/R2NorthstarTools/ns-linux-dbg)

To run it simply invoke it: `./nsdbg.py`\
It supports a variety of options as well as vanilla wine and Proton, use the help flag to see all possible options: `./nsdbg.py --help`
