{% hint style="warning" %}
If you are not experienced with x64dbg it its recommended to use [Visual Studio](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

* Do make debugging easier it is suggested to change your settings to the following:
  * Keeping System Breakpoint enabled is optional but useful

  * Skipping INT3 stepping is recommended to prevent generic breakpoints from stopping the program

  * 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

* 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`
