Switch Game Merger Utility is a tool (written in Rust) that can merge NSP and XCI files from multiple parts into a single file.
Current supported operating system(s):
- MacOS (Silicon)
- Linux
User guide
How to use
To use the program, simply launch the downloaded program.
- Select if your game files you are going to merge are NSP or XCI.
- Click "Select Game Files" and choose all of the NSP/XCI files to be merged.
- Enter a output name - WITHOUT the .nsp or .xci extension (EX: My Merged Files).
- Click "Start".
The program will say "Finished!" when completed, and the file will be in the same directory as the program.
There is no need to add .nsp or .xci when entering the name, as the program will do this for you.
NSZ/XCZ/NCZ decompression
On MacOS, you will need to place the prod.key in your home directory, in a .switch directory.
It will look like this: /Users/MY_USERNAME_HERE/.switch/prod.keys
Without the prod.keys, you cannot decompress NSZ files.
NSZ decompressor is the https://github.com/nicoboss/nsz utility compiled to a portable binary with pyinstaller. All credit goes to them for creating this tool.
You will need the _internal directory and the NSZ file in the same directory as the program in order for it to work.
