This is the file format used for Nintendo Switch digital games.
The string of characters in the title isn't random—it tells you exactly what the file is:
This means the file is compressed. You will need a program like 7-Zip or WinRAR to extract the actual NSP file. 2. Safety First
If a "download" ends in .exe or .msi , do not run it. A game file for the Switch should only be an .nsp or .xci after extraction.
Urban Cards is a relatively small indie game. If the download is only a few kilobytes or several gigabytes larger than expected, it’s likely a fake file. 3. Usage Requirements
To actually play an NSP file, you generally need one of two things:
Your console must be running Custom Firmware (CFW) like Atmosphere. Installing NSPs on a vanilla console will result in an immediate ban from Nintendo’s online services.
If you are searching for a download like you are likely looking for a digital copy of the roguelike deck-builder for the Nintendo Switch.
