Open Goldleaf on your Switch, navigate to "Explore Content," find your file, and select "Install". Step 3: Managing the 3DLC Pack

Before handling NSP files, ensure your device and environment are ready:

Installing NSP files from unofficial sources carries risks. Always use 90DNS or to hide your serial number and block Nintendo's servers to prevent your console from being banned from online services.

Connect your Switch to your PC via USB-C. Open DBI on the Switch and select "Run MTP Responder." Your Switch will appear as a drive on your PC.

This guide focuses on the technical process of managing and installing these files safely on a modified console.

You must have the latest signature patches installed on your SD card; without these, the console will refuse to launch unauthorized NSP files. Step 2: Choosing an Installation Method
