Are you currently encountering a specific error code or a "software closed because an error occurred" message when trying to boot the update? Deltarune 1.02 update out now, patch notes

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

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.

Overview: The Dynamic Chapter-Unified Patching Engine is a backend feature for a Switch content management tool (like a "Deltarune Chapter Manager"). It solves the common issue where updating a multi-chapter game via NSP files results in duplicate icons, missing save data, or version mismatches between chapters (e.g., Chapter 1 being version 1.0 while Chapter 2 is 2.0.4).

This feature automatically detects, validates, and merges disparate update NSPs into a single unified game entity, ensuring seamless transitions between chapters.
