As I sat in front of my computer, I couldn't help but feel a surge of excitement. I had just downloaded the latest update for Deltarune, the critically acclaimed RPG from the creators of Undertale. I had heard that Chapter 1 & 2 Switch NSP Update was now available, and I was eager to dive back into the world of Deltarune.

As I booted up the game, I noticed that the update had indeed been applied. The menu screen now reflected the new changes, and I could see that the update had added some exciting new features. I selected the option to play Chapter 1 & 2, and the game began to load.

As the chapter loaded, I was greeted by the familiar face of Kris, the protagonist of Deltarune. I remembered the events of Chapter 1, where Kris and their friend Susie had stumbled upon a mysterious RPG world. Now, with the update, I was ready to experience the next chapter of the story.

As I played through Chapter 1 & 2, I was struck by the seamless transition between the two chapters. The update had clearly done its job, and the game now felt even more cohesive. I encountered new characters, explored new areas, and made choices that would impact the story.

At one point, I came across a choice that made me pause. Should I go left or right? The consequences of my decision were unclear, but I knew that it would have a significant impact on the story. I thought back to my previous playthroughs of Deltarune and how my choices had led to different outcomes.

After some deliberation, I made my decision and continued on. The story unfolded in a way that was both unexpected and engaging. I found myself fully immersed in the world of Deltarune, eager to see what would happen next.

As I reached the end of Chapter 2, I felt a sense of satisfaction. The update had breathed new life into the game, and I was excited to see what the future held for Deltarune. I saved my progress and closed the game, already looking forward to my next playthrough.

The Deltarune Chapter 1 & 2 Switch NSP Update was a resounding success, and I was grateful to have experienced it. The game had improved significantly, and I was eager to see what other updates would come in the future.

How was that? Did I meet your expectations?

For users looking to update Deltarune Chapters 1 & 2 on a modded Nintendo Switch using NSP files, the process involves installing a separate update file to enable Chapter 2 and the latest bug fixes. Originally, Chapter 2 was released as a free update to the existing Chapter 1 base. On official firmware, this is handled via the eShop, but for modded systems, you must manually apply the update NSP to your existing base game installation. Essential Files and Preparation

To ensure the update works correctly, you need three main components:

Base NSP: The original "Deltarune Chapter 1" base game file.

Update NSP: The specific update file (e.g., version 1.0.x) that adds Chapter 2 and subsequent patches.

Signature Patches (Sigpatches): Always ensure your Custom Firmware (CFW) has the latest sigpatches installed, or the new NSP will fail to launch with an "unable to start software" error. Installation Guide for Modded Systems

There are two primary ways to make the update work on your console: Method 1: Direct Installation (Tinfoil or Goldleaf)

This is the most common method for users who already have the base game installed.

Transfer Files: Place your update NSP file into a folder on your SD card (e.g., /NSPs/). Launch Installer: Use an app like Tinfoil or Goldleaf.

Install Update: Navigate to your SD card, select the update NSP, and choose Install. The installer will automatically detect the base game and apply the update over it.

Verification: After installation, the game icon should change, or you should see "v1.0.x" when pressing the + Button on the Home Menu. Method 2: Combining Files (Swiss Army Knife / SAC)

If you are starting fresh, you can merge the base game and update into a single "super" NSP. Open SAC: Use the Swiss Army Knife (SAC) app on your PC.

Select Files: Load your base NSP and your update NSP into the tool.

Merge: Click Update NSP file to create a consolidated file that contains both chapters and all current fixes.

Install: Transfer this new file to your Switch and install it once. Common Troubleshooting If the update isn't appearing or Chapter 2 is locked:

For standard users, this update is downloaded automatically or through the "Software Update" option on the Switch home screen. If you are using an NSP (Nintendo Submission Package) for a modded system:

Data Transfer: Save data from the original free "demo" version (Chapters 1 & 2) is transferable to the newer paid versions.

Beat the Chapter: To successfully carry over progress from Chapter 1 to Chapter 2, you must beat the first chapter and watch the end credits to update your "completion data".

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

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

To get the Deltarune Chapters 1 & 2 NSP and its updates working correctly on your Nintendo Switch, you typically need to install the base game file followed by the update file using a homebrew installer. Installation Steps

For a smooth setup on a modded console, follow this sequence:

Prepare Files: Ensure you have both the Base NSP (Chapters 1 & 2) and the latest Update NSP (e.g., v1.02 or higher). Use a Reliable Installer:

Goldleaf: Copy your files to an NSPs folder on your SD card. Open Goldleaf, navigate to Explore content > SD card, select the base file first, then the update, and choose Install.

Tinfoil: Alternatively, use Tinfoil to browse your SD card's root and install the files directly. Some users prefer the "MTP responder" mode in DBI to drag-and-drop files from a PC.

Install Order: Always install the Base Game before the Update. Installing them out of order can sometimes cause the game to fail to boot. Troubleshooting Common Issues

Version Mismatch: Ensure your update file matches the Region/Title ID of your base game. If they don't match, the Switch will treat them as two separate entries or the update simply won't apply.

Corrupt Data: If the game crashes, use the Switch's system settings to Check for Corrupt Data or perform a hard restart by holding the power button for 15 seconds.

Firmware Requirements: Latest updates (like v1.02) may require a higher system firmware. Ensure your custom firmware (CFW) and Sigpatches are up to date to avoid "Unable to start software" errors.

Merging Files: If you prefer a single file, you can use tools like Switch Army Knife (SAK) on a PC to merge the base NSP and the update into one consolidated file before installing. Nintendo Switch NSP Combination Install Tutorial

Understanding Deltarune Chapters 1 & 2: Switch NSP Updates and Compatibility

Toby Fox’s Deltarune has captivated fans since its surprise release, offering a deep, character-driven experience that expands on the legacy of Undertale. For players on the Nintendo Switch, managing the game—specifically ensuring that Chapters 1 and 2 are fully updated and functional—is key to a smooth journey through the Dark World.

Whether you are a new player or a returning fan looking to verify your game files, here is everything you need to know about making Deltarune Chapters 1 & 2 work effectively on your Switch. The Evolution of Deltarune on Switch

Originally, Deltarune Chapter 1 was released as a standalone demo on the Nintendo eShop. However, with the arrival of Chapter 2, the game was rebranded and updated to a single package: Deltarune Chapters 1 & 2.

For those using NSP (Nintendo Submission Package) files for archival or backup purposes, it is vital to understand that the "Update" file is what merges the two chapters into one playable experience. If you only have the base Chapter 1 file without the subsequent update, you will be unable to access the Chapter 2 content. Key Features of the Chapters 1 & 2 Update

Updating your game to the latest version does more than just add content; it refines the engine and ensures cross-chapter compatibility. According to the Deltarune Wiki, the game features a unique character creation and introduction sequence that sets the stage for the entire narrative.

Content Expansion: The update adds approximately 6 additional hours of gameplay, bringing the total experience to roughly 9 hours.

Save Data Transfer: A critical function of the update is the ability to carry over your choices from the first chapter. Players can load completion data from Chapter 1 even if the original save file was deleted, provided they saw the credits.

Performance Fixes: Updates often include "under-the-hood" stability improvements, ensuring that the pixel-art graphics and bullet-hell combat run smoothly in both handheld and docked modes. How to Ensure Your Update Works

If you are managing your game files manually via NSPs, follow these steps to ensure the update is properly applied:

Check Version Numbers: Ensure your update file matches the region of your base game (e.g., US, EU, or JP). Mismatched regions will prevent the update from "working" or appearing in the Switch menu.

Verify File Integrity: If the game fails to launch after an update, the NSP may be corrupted. Re-dumping or re-acquiring the file often resolves these "work" issues.

System Firmware: Some updates require a minimum system firmware version. If your Switch is on older software, the Deltarune update may fail to install or run. Future Outlook

While Chapters 1 and 2 are currently free, Toby Fox has indicated that future installments (Chapters 3, 4, and 5) will be a paid release. Fans have speculated on the length of these upcoming sections, with some theories suggesting that Chapters 3 and 4 together may be longer than the first two combined. There are even fan-driven discussions regarding "Chapter 7" and beyond, though official details remain scarce.

For the best experience, it is always recommended to use the official Nintendo eShop version of the game, which handles updates automatically and ensures your save data remains secure for future chapters.

how long do you think the full game will be once it's fully released? on Switch: How to Get Chapters 1-4 Working

This paper discusses the technical challenges of patching Unity-based games on the Nintendo Switch, specifically focusing on how the transition from standalone Chapter 1 to the combined Chapter 1 & 2 release functioned in the context of file formats like NSP.

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.

Step 4: Boot Using Fusee (Crucial Fix)

Most "update work" failures happen due to booting via Hekate without fss0 patches.

Do: Boot using fusee.bin from the SD card root.
Why: fusee.bin loads full sigpatches and KIP patches, which are required for Deltarune’s update to bypass Nintendo’s anti-CFW checks.

Problem 1: "Corrupt Data" After Installing the Update

Symptom: The base game works perfectly. After installing the update NSP via Tinfoil or Awoo, the Switch says the data is corrupt and prompts a re-download.

The Fix: This is almost always a Signature or Firmware issue.

Update your CFW: Ensure you are on the latest Atmosphere 1.6.2 (or higher) and Hekate 6.1.0.
Update your Switch Firmware: Deltarune Chapter 2 requires Firmware 13.0.0 or higher. The v1.0.2 update requires Firmware 15.0.1+. If you are on Firmware 14.x, the update NSP will fail to install correctly.
Reinstall Sigpatches: Outdated sigpatches are the #1 reason updates don't work. Download the latest sigpatches (for Atmosphere) and boot via Fusee.bin.

Conclusion

For users working with NSP files on the Nintendo Switch, Deltarune Chapters 1 & 2 represent a straightforward, stable experience. The key to success is understanding that the game is a single entity, and the “Chapter 2 update” is simply an unlock mechanism applied on top of the base NSP. As long as you use matching Title IDs and a modern installer, the update works perfectly, granting full access to Toby Fox’s surreal, heartfelt RPG adventure from start to current finish.

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.

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

As of late 2025, several patches have addressed bugs across Chapters 1 and 2: Nintendo Switch NSP Combination Install Tutorial

To update Deltarune Chapter 1 & 2 (currently as an NSP for a modded Nintendo Switch), you need to install the separate update file through a homebrew manager like Goldleaf or Tinfoil, or merge it using Switch Army Knife (SAK). Latest Version Status

Choose to install to the SD Card (recommended) or console memory. Via PC (NSP Merging): Use the Switch Army Knife (SAK) app. Place your Nintendo keys in the bin folder.

Select Update NSP, choose your Base NSP, and then select your Update NSP.

The tool will output a single, updated NSP file that you can then install as one package. Key Update Features (v1.02/v1.03)

Save Transfers: Improved save data import from old demo versions to the full chapters 1–4 release.

Bug Fixes: Addressed color errors in specific areas, character duplication bugs in the closet, and piano-stuck issues.

New Content Support: Updates often prepare the game for upcoming chapters (Chapters 3 & 4 are confirmed as free updates for existing owners). Managing Save Files
