sys-con comes with a config folder located at `sdmc:/config/sys-con/`. It contains options for adjusting stick/trigger deadzone, as well as remapping inputs. For more information, see `example.ini` in the same folder. All changes to the files will be updated in real time.
You will need to compile and use the master branch of [libnx](https://github.com/switchbrew/libnx) due to a [dependency](https://github.com/switchbrew/libnx/commit/c3b0b63471ee5309ea5040ad98f21919022ac9c7) in libstratosphere.
If you have **Visual Studio Code**, you can open the project as a folder and run the build tasks from inside the program. It also has Intellisense configured for switch development, if you have DEVKITPRO correctly defined in your environment variables. Handy!
Otherwise, you can open the console inside the project directory and use one of the following commands:
`make -j8`: Builds the project and its dependencies (libstratosphere) and places the resulting files in the output folder (out/). The -j8 means it will create 8 separate threads to speed up the building process. Make it lower if it freezes up your system.
`make clean`: Cleans the project files (but not the dependencies).
`make mrproper`: Cleans the project files and the dependencies.
