Match the Title ID: Ensure your update NSP matches the Title ID of your base game. Different regions or versions (like the older demo vs. the newer full-game demo) may have different IDs. Use a Reliable Installer:
DBI: Recommended for stability. Use the DBI backend to install from your PC via USB.
Tinfoil: Open Tinfoil and check the "New Updates" section; if your Switch is connected to a shop, it should find the update automatically.
Goldleaf/Awoo: Good alternatives for manual NSP installation.
Combine Files (If Installation Fails): If the update still won't stick, you can use a tool like Swiss Army Knife (SAC) on your PC to "bake" the update and the base game into a single consolidated NSP file.

Deltarune Chapters 1 & 2 on a modded Nintendo Switch, ensuring an NSP update works correctly requires matching the update file to your base game's Region and Title ID. Users often encounter "The software was closed because an error has occurred" when these files are mismatched or if signature patches are outdated. Troubleshooting the NSP Update
If your update is not showing or the game is crashing after installation, check the following: Signature Patches (Sigpatches):
Most update failures or "Unable to start software" errors are caused by outdated sigpatches. Ensure your Atmosphere/CFW sigpatches are updated to the version matching your Switch firmware. Title ID and Region Match:
The NSP update must match the Title ID of your base game (e.g., the US version update will not work on a Japanese base game). Installation Tool: Awoo Installer fails, users often find success using
, which can sometimes automatically fix "invalid NCA" errors during installation. Merge Files: Some users prefer using tools like NSC Builder
to merge the base NSP and the update into a single "Super NSP" file to avoid separate installation issues. Save Data Conflicts (Chapter 1 to 2)
A common issue isn't the update itself, but the game failing to recognize save data between chapters or across different versions of the demo. Old vs. New Demo:
If you have save data from the "original" Chapter 1 demo and the "new" Chapter 1+2 version, the game may crash or fail to import. Delete save data for the version you are currently playing in System Settings > Data Management > Delete Save Data to clear the conflict. Import Prompt:
To trigger the import prompt again if you accidentally skipped it, you may need to delete the "full version" save data while keeping the demo save data on the console. Version 1.02 Improvements

For users of a modified Nintendo Switch looking to update DELTARUNE Chapters 1 & 2
via NSP files, the process involves manually patching the base game with an update file using community-developed tools. Because official servers can ban modded consoles, these files must be installed offline. How to Update Using NSP Files
To successfully apply an update to your game, you typically need three components: your console's Nintendo keys, the base game NSP, and the update NSP.
Merging with SAC (Swiss Army Knife): You can use the Swiss Army Knife (SAC) app on Windows to combine the base game and update into a single, consolidated NSP. NSP Update Details The NSP (Non-Standard Package) update
Direct Installation: Alternatively, tools like DBI or Goldleaf allow you to install the update NSP separately over the existing base game on your console.
Transferring Files: For a direct USB transfer from your PC to the Switch, the NS USB Loader is often used to send the files to your preferred installer on the console. Troubleshooting Common Issues
If your update does not appear to "work" or the game fails to launch after patching, consider the following:
Sigpatches: Ensure your custom firmware has the latest sigpatches installed; without these, the console may refuse to boot modified or updated NSP files.
Version Mismatch: Some updates require a specific minimum firmware version. If your Switch system software is too old, the updated game may not launch.
Demo vs. Full Version: Note that as of June 2025, the original "demo" version and the "full" version (which includes Chapters 1-4) are often treated as separate software IDs. If you have an update for the full version, it will not work on the older standalone demo NSP.
Save Data Import: If you are moving from a demo version to a newer release, the game should prompt you to import save data upon the first launch, provided no save data for the new version already exists. Official Update History

Title: Technical Analysis of Content Delivery and Patch Architecture: The Deltarune Chapter 1 & 2 Nintendo Switch Update Case Study
Abstract
This paper examines the technical infrastructure surrounding the deployment of Deltarune Chapter 2 on the Nintendo Switch. It analyzes the shift from a standalone distribution model for Chapter 1 to a bundled "Chapter 1 & 2" package. Specifically, this document explores the mechanics of the Nintendo Submission Package (NSP) format, the role of delta patches (updates), and the file system restructuring required to facilitate a seamless transition between software versions. The purpose of this analysis is to clarify how "update work" functions in modern console environments when a standalone title is converted into a bundled episodic application.
5.1. Title ID Management Nintendo assigns a unique Title ID to every piece of software. If the developer changes the architecture significantly, they may issue a "new" application, rendering the old update channel dead. In Deltarune's case, the update mechanism had to ensure that users who downloaded Chapter 1 for free could update to the bundle without re-purchasing, requiring specific entitlement checks on the Nintendo server side.
5.2. Save Data Persistence
A critical aspect of the update's functionality was ensuring that save.dat files created in Chapter 1 were correctly recognized by the Chapter 1 & 2 executable. This required the update to maintain the same unique user ID association and file pathing structure, despite the internal game code changing to support a chapter select screen.
Toby Fox (the creator of Deltarune and Undertale) has always supported fan content, ROM hacks, and even watching full playthroughs. However, he’s also clear: the free eShop version is the best way to play.
If you use NSP files solely because your Switch is banned, or you’re preserving an offline backup, that’s one thing. But if you just want to enjoy the game? Download it officially for free in under two minutes. No CFW required, no update hunting, and you support the developer’s metrics for future console ports.
To understand the "update work," one must first define the container format.
2.1. Nintendo Submission Package (NSP) An NSP file is essentially an archive containing multiple NCAs (Nintendo Content Archives). These NCAs hold the executable (the game logic), the romfs (game assets like images and music), and meta-data.
2.2. Base vs. Update In the Switch ecosystem, game updates are not typically distributed as full re-downloads of the game. Instead, they are distributed as "Patch Archives."
When an update is installed, the Switch operating system creates a layered filesystem. It retains the "Base" data and overlays the "Update" data on top. If a file in the Base is replaced, the Update version takes precedence. If a file is new, it is simply added to the virtual filesystem.
A critical issue with Switch NSP updates for episodic games is the potential for the save file location to be re-indexed, causing the "New Game" button to be the only option after an update.
