Title: Digital Preservation and Distribution Models on the Nintendo Switch: A Technical Analysis of NSP and XCI File Formats in Super Mario Odyssey
Abstract
This paper provides a technical examination of the file architectures used in Nintendo Switch software distribution, specifically contrasting the Nintendo Submission Package (NSP) and NX Card Image (XCI) formats. Using the critically acclaimed title Super Mario Odyssey as a case study, we analyze the structural differences between digital distribution dumps and physical cartridge dumps. Furthermore, this document explores the role of update files (often denoted as mise à jour or patches) in maintaining software integrity and the challenges associated with "high quality" preservation in the context of modern DRM and copyright protection.
1. Introduction
The Nintendo Switch console utilizes a proprietary operating system and file structure distinct from its predecessors. Software distribution occurs via two primary vectors: physical Game Cards and digital distribution via the Nintendo eShop. For the purposes of digital archiving and preservation, these vectors produce two distinct file formats: XCI (physical) and NSP (digital). Understanding the distinction between these formats is essential for both software archivists and developers interested in the structural integrity of modern console software.
Super Mario Odyssey, released in 2017, serves as an ideal subject for this analysis due to its large file size, extensive post-launch support through updates, and universal acclaim, making it a high-priority target for high-quality preservation.
2. File Format Architectures
2.1 The XCI Format (NX Card Image) The XCI format represents a 1:1 bitwise copy of a Nintendo Switch Game Card. Structurally, an XCI file mimics the physical partitions of the cartridge ROM.
2.2 The NSP Format (Nintendo Submission Package) The NSP format is derived from the digital distribution ecosystem (eShop). It functions similarly to an archive (conceptually akin to a ZIP file) containing the encrypted content files (NCA - Nintendo Content Archive) and a Ticket file required for authorization. super mario odyssey switch nsp xci mise a jour high quality
3. Software Updates: The Role of "Mise à Jour"
Modern triple-A titles rarely ship in a "final" state; Super Mario Odyssey received several post-launch patches (updates) to optimize performance and add features (such as the
Super Mario Odyssey , achieving high-quality performance on Nintendo Switch or through emulation depends heavily on applying the correct software updates and choosing the right file format (NSP or XCI). Core Game Updates
The latest major updates significantly enhance the experience, especially for players moving to newer hardware or using emulators: Version 1.4.1 (Released June 2025)
: This update is a high-quality "Switch 2" optimization. It provides a significant resolution boost , nearly eliminating aliasing. It also introduces HDR support
, allowing two players to play together (one as Mario, one as Cappy) over local or online GameChat. Version 1.2.0
: This version is essential for core gameplay additions, including Luigi’s Balloon World and various new outfits and hint arts. Essential Files : To play updated versions, you generally need the base game file (v1.0) and the specific update NSP
. Updates are cumulative, meaning v1.4.1 includes all previous improvements from v1.2.0 and v1.3.0. NSP vs. XCI Formats Title: Digital Preservation and Distribution Models on the
Understanding these formats is key to managing your digital library: NSP (Nintendo Submission Package)
: These are digital eShop files. They are generally smaller (base game is ~5.7 GB) but require separate update NSPs to be installed afterward. XCI (Switch Cartridge Image)
: These are direct dumps from physical cartridges. They can sometimes be larger because they include "empty" cartridge space, but many "Super XCI" files come pre-updated with the latest software versions.
: These are highly compressed versions of NSP and XCI designed to save storage space. Optimizing High-Quality Performance To get the best visual fidelity and stability:
An exploration of Super Mario Odyssey through the lens of technical formats (NSP and XCI) and high-quality updates reveals a game that has evolved significantly since its 2017 launch. While originally a 900p docked experience on the first Nintendo Switch, the title has become a focal point for visual enhancement through official updates and community modifications. Technical Foundations: NSP vs. XCI Understanding the "high quality" delivery of Super Mario Odyssey begins with the file formats used in modding and emulation: XCI (Nintendo Cartridge Image):
These files are digital "dumps" of the physical game cartridge. They are often preferred by collectors because they can sometimes "bake in" updates and DLC into a single file, allowing for a cleaner setup on modified systems. NSP (Nintendo Submission Package): This format mirrors digital eShop titles. Critically, updates and DLC Super Mario Odyssey
are typically delivered as NSPs, even for those using XCI base files. The Evolution of High-Quality Visuals The quest for "high quality" in
spans two distinct paths: official hardware transitions and community-driven emulation. 1. Official Hardware Upgrades With the introduction of the Nintendo Switch 2, Super Mario Odyssey received a significant free update Structure: XCI files contain a "secure" partition where
