Python script that splits NSP files into 4GiB chunks so that they can be installed from FAT32 filesystems.

User guide

To run it you'll need Python3 installed. Once installed, call the script from Terminal or Command Prompt with the following:

python3 splitNSP.py filename.nsp

By default this will make a copy of the NSP and split it up into parts. Once created, you'll need to open the folder's properties and check the Archive flag. This is easily done on Windows. You can also set the archive flag on a folder directly on the Switch using a homebrew such as NX-Shell.

You can also activate quick mode with this command:

python3 splitNSP.py -q filename.nsp

This will not make a copy of the NSP and instead will split the original. This is useful if you're running low on space as it only requires that you have 4GiB of temporary space to run it. It's also much faster.

Once the folder is made and the archive flag is set copy it to your SD card (sdmc:/tinfoil/nsp/ if using tinfoil) and install it like any other NSP.
