Switch XCI Extractor

The Switch XCI Extractor is a domain-focused utility designed for developers, archivists, and researchers who work with Nintendo Switch XCI images. It solves the problem of discovering, validating, and extracting embedded assets and metadata from a dump, enabling cataloging, offline analysis, and integration into data pipelines. It operates on a local XCI file, avoiding network access or external dependencies, and produces structured outputs that preserve source structure while exposing key artifacts. Typical use involves preparing a dump for inventory, verification, or examination of content metadata without modifying the original file. It targets users who need repeatable, auditable access to a dump's components and their metadata.

Core Logic & Features: the tool parses the XCI container by reading the header to locate partitions and offsets, then resolves content boundaries for tickets, certificates, CNMT metadata, and content NCAs. Required features include input validation, header parsing, artifact discovery, and safe extraction of selected NCAs; outputs include a metadata JSON and artifact files. Optional features include filtering by content type, batch processing, and signature or CRC checks when keys are supplied. It supports exporting metadata in JSON and human-friendly XML-like notes, and can produce a compact artifact bundle for automated workflows. It does not decrypt data unless proper keys are provided, and it never writes to the source XCI image.

Audience, differentiators, and practical use: the tool serves developers building XCI workflows, archivists cataloging game dumps, QA engineers validating data integrity, and researchers exploring Nintendo's image format. Its differentiators include adherence to the official container structure, explicit artifact naming, deterministic extraction, and outputs tailored for automation. Practical use cases include creating a content inventory from a dump, validating partition integrity before archival, exporting CNMT and ticket metadata for analysis, and generating a ready-to-import artifact bundle for archival systems or forensics workflows. Compliance notes emphasize legal use of dumped data and respect for copyright, with clear boundaries on decryption and distribution.
