How to Split NSP Files Safely on Chromebook Devices

For gamers who enjoy using modded or homebrew features on their Nintendo Switch, NSP files are a common format. However, due to size restrictions or storage limitations, it’s often necessary to split these NSP files. If you are using a Chromebook, the process can seem daunting at first. Chromebooks use Chrome OS, which is a different environment than traditional Windows or macOS systems. That means you need to approach file management tasks slightly differently—but safely and efficiently splitting NSP files on a Chromebook can absolutely be done.

Understanding NSP Files and Why They May Need Splitting

NSP (Nintendo Submission Package) files are used to install games and applications on Nintendo Switch systems through homebrew methods. These are large files that, in many cases, exceed FAT32’s maximum file size of 4GB. This poses a challenge when transferring files via SD cards formatted to FAT32, which is commonly the most compatible format for the Switch.

To work around this issue, users split the NSP files into smaller parts, enabling successful transfers while avoiding data corruption.

Attempting to split NSP files without the proper tools or knowledge can result in corrupted files, data loss, or rendering the file unusable by the system. On Chromebooks, where traditional Windows software can’t be installed directly, users must utilize Chrome-compatible and Linux-based tools to carry out safe splitting.

Preparing Your Chromebook for NSP File Management

Before beginning, there are a few essential steps a user must take to prepare their Chromebook for file splitting:

  • Enable Linux (Beta) on your Chromebook from the system settings.
  • Update Linux and install necessary packages.
  • Download a file-splitting tool compatible with Linux—such as split, NSPsplitty, or hacPackTools.
  • Ensure that the NSP file is stored in a location accessible to the Linux environment.

If Linux (Beta) isn’t enabled:

  1. Go to Settings on the Chromebook.
  2. Scroll to Developers and enable Linux (Beta).
  3. Let the installation process finish—it might take a few minutes.

Using the Terminal to Split NSP Files

Once Linux is installed, open the Terminal application from the launcher. The Terminal is your gateway for running commands needed to split NSP files efficiently.

Method 1: Using the Split Command

The simplest way to split a file in Linux is by using the built-in split command. Here’s how to do it:

split -b 3G mygame.nsp mygame_part_

This command splits the file “mygame.nsp” into chunks of 3GB each. The parts will be labeled sequentially (e.g., mygame_part_aa, mygame_part_ab, etc.).

Things to Note:

  • The -b flag determines the size of each chunk. Adjust it as needed depending on your SD card’s limitations.
  • Be sure to rename the parts properly afterward if the target device requires a specific naming convention.

Method 2: Using NSPsplitty

NSPsplitty is a small utility designed to split NSP files correctly, keeping in mind file integrity. Though there’s no official Chrome OS build, it works perfectly within your Linux container.

Install NSPsplitty with the following:

sudo apt install mono-complete

Then, run NSPsplitty via the Mono runtime:

mono NSPsplitty.exe

This provides a GUI-style interface or CLI depending on the version. Follow the on-screen prompts to select and split your NSP files.

Helpful Tip: Store the files in the Linux Files directory for easier access and manipulation.

Rejoining NSP Files (Optional)

If you ever need to combine the NSP files again, the cat command on Linux does the job:

cat mygame_part_* > mygame_rejoined.nsp

This will reconstruct the original NSP file as long as all parts are present and correct.

Important Safety Tips

When working with large NSP files, it’s important to follow safety practices to avoid corruption or data loss:

  • Backup the original NSP file before doing any splitting.
  • Use reliable SD cards and USB drives to avoid damaged transfers.
  • Avoid interrupting the splitting process once initiated.
  • Verify file integrity using checksums or hash comparisons after transfer.

Also, keep in mind that distributing copyrighted NSP files without authorization is illegal in many regions. Always ensure you are working with legally obtained backups of games that you own.

Common Errors and Troubleshooting

Certain issues may arise during the process. Here are some of the most common and how to resolve them:

  • Error: “Command not found” – Ensure you’ve enabled Linux and installed the required tools correctly.
  • File doesn’t run on the Switch after transfer – The file might be corrupted. Double-check the size of each part and re-split if necessary.
  • Linux Terminal doesn’t recognize file paths – Make sure your files are stored in the Linux Files section or direct Linux-accessible paths.

Alternatives to Chromebook Splitting

If you find the setup on Chromebook too complicated, you can consider using:

  • A secondary Windows or Linux-based PC for initial file handling.
  • Cloud storage solutions like Google Drive to temporarily store files and manipulate them using remote desktop environments.

However, many users find that once set up properly, handling NSP file splitting via Chromebook becomes second nature and saves time in the long run.

Conclusion

While splitting NSP files on Chromebook devices may require some initial configuration, it’s entirely feasible with the help of Linux (Beta) tools and a bit of Terminal knowledge. Adhering to file size limits, maintaining backups, and using the correct commands ensures safe and efficient operation. With these steps in mind, Nintendo Switch enthusiasts can confidently manage and transfer large NSP files directly from their Chromebook without jeopardizing file integrity or usability.

Frequently Asked Questions

Q: Do I need to root my Chromebook to split NSP files?
No. Enabling Linux (Beta) in the settings is sufficient. No rooting or developer mode is required.
Q: Can I use Android apps to split NSP files?
While technically possible, most Android file splitters are not reliable for NSP files which require specific formatting. Linux tools are far more dependable.
Q: Are there any GUI tools that work well on Chromebook?
Yes. If you install Mono for Linux, you can run some GUI-based tools such as NSPsplitty with a visual interface.
Q: How do I copy the split files onto my SD card?
Use the Files app to move them to your SD card. If it’s formatted as FAT32, ensure each split part is under 4GB.
Q: Will splitting an NSP file affect gameplay?
No, as long as the parts are properly split and merged (if needed), the integrity of the game will remain intact.
