NUT Github all releases

Nut is a multi-purpose utility to organize, manage, and install Nintendo Switch files (NSP, NSZ, XCI, XCZ). It has the ability to act as a USB and network server for Tinfoil.



  • Scan - populates file list
  • Organize Files - moves files on disk to match the format specified in the configuration
  • Pull - gets new files that match your filters from the remote locations (see configuration)
  • Update TitleDB - force-reloads the latest title database
  • Decompress NSZ - for any NSZ.XCZ files found, uncompresses them to NSP/XCI
  • Compress NSP - for any NSP/XCI files found, compresses them to NSZ/XCZ CPU INTENSIVE
  • Setup GDrive OAuth - see below


The GUI has the ability to set the most common configuration options, see the below images. You can also create a custom configuration by creating

. The format should mirror nut.default.conf.

Filters Local Paths Local Scan Remote Scan

The IP/Port/User/Password are the information needed to login to the NUT server. To the right of those, you can also see a

USB Status
indicator, indicating whether a Tinfoil client is connected via USB with the server.

THe body shows a table containing a list of files that were detected by NUT from the scanned paths. It shows the title count, file name, title ID, title type and title size for each scanned file.

The footer shows the progress information of any file that is currently being downloaded from the server.

Google Drive Integration

NUT has the ability to interact with Google Drive. For this to work, you will need to download a

, using the guide found here. Once you have this file placed either in NUT's root or conf directory, click the Setup GDrive OAuth button in the GUI and follow the prompts. You will be able to access your GDrive through Tinfoil via the
protocol after copying
on your microSD card. (This is automatically done if you connect Tinfoil to nut)

Usage guide (Windows users)

  • Download
    from here.
  • Install the drivers by running the
    in the previous step.
  • Run
    . You should be presented with a GUI as shown in the picture above.
  • Install the latest version of Tinfoil and open it.

Usage guide (UNIX users)


  • Python 3.9+ (tested:
  • OpenSSL-backed curl (for pycurl)
  • Python modules as listed in

Installation guide (Linux)

  • Install Python 3.9+ from your preferred package manager, along with the libusb, python3-pip & python3-pyqt5 packages
  • Install curl with the openssl backend - install libssl-dev (ie, apt install libssl-dev libcurl4-openssl-dev)
  • Clone this repository to desired directory and change your working directory to the cloned repository
  • Install the PIP modules with the following command pip3 install -r requirements.txt. If you previously tried installing pycurl and get the error libcurl link-time ssl backend (openssl) is different from compile-time ssl backend (none/other), uninstall it, make sure to follow step 2 again (installing curl with the openssl backend), and pip3 install pycurl --no-cache-dir
  • Add the following code snippet to /etc/udev/rules.d/99-switch.rules using your favorite editor and reload (udevadm control --reload). Note: you may need to Disable MTP within Tinfoil and replace the group user with another that exists on your system. (based on this comment)

    SUBSYSTEM=="usb", ATTRS{idVendor}=="16c0", ATTRS{idProduct}=="27e2", GROUP="plugdev"
  • Run python3 to launch the application. (python3 for CLI)

Installation guide (macOS)

  • Install Python 3.9 and PyQt5 via Homebrew (brew install [email protected] [email protected])
  • Install pyenv: pyenv + pyenv-virtualenv (brew install pyenv pyenv-virtualenv and follow install directions)
  • Install libusb (brew install libusb)
  • Install curl with the openssl backend (brew uninstall --ignore-dependencies curl && brew install curl)
  • Install Python 3.9.7 with pyenv and set it as the default (pyenv install 3.9.7 && pyenv global 3.9.7)
  • Load the system python's site-packages via pyenv's python. This is required to use PyQT5 from Homebrew.
    • Get the Homebrew Python site-packages path (via brew info [email protected]).
    • Add it to the load path of your pyenv's Python install (cd pyenv root).
    • To do this, go to the site packages directory of your pyenv install (ie. $HOME/.pyenv/versions/3.9.7/lib/python3.9/site-packages) and create an file named homebrew.pth containing the path for Homebrew Python's site packages directory (ie. /opt/homebrew/lib/python3.9/site-packages)
    • For example, for M1, it would be: cd $HOME/.pyenv/versions/3.9.7/lib/python3.9/site-packages && echo "/opt/homebrew/lib/python3.9/site-packages" >> homebrew.pth
  • Clone this repository to desired directory and change your working directory to the cloned repository
  • Create a virtualenv and activate it. Note that your python path will be different if not on M1. (pyenv virtualenv --system-site-packages --python=/opt/homebrew/bin/python3 nut && source activate nut)
  • Install wheel (pip install wheel)
  • Install pycurl using the below.
    on M1:
    PYCURL_SSL_LIBRARY=openssl LDFLAGS="-L/opt/homebrew/opt/openssl/lib" CPPFLAGS="-I/opt/homebrew/opt/openssl/include" pip install pycurl
    on Intel:
    PYCURL_SSL_LIBRARY=openssl LDFLAGS="-L/usr/local/opt/openssl/lib" CPPFLAGS="-I/usr/local/opt/openssl/include" pip install pycurl --compile --no-cache-dir
  • Install all other dependencies (pip install -r requirements.txt)
  • Run python for CLI. Run python3 to launch the application (this will only work if PyQT from Homebrew was succesfully installed via directions above)
