XNB extractor

XNB extractor enables researchers and developers to access embedded assets inside XNB game content files produced by XNA/MonoGame pipelines. It targets textures, audio, fonts, and metadata, providing a non-destructive way to inspect and reuse assets. Primary users include game developers needing assets for documentation or reuse, modders collecting resources for experiments, and archivists preserving historical content. The tool operates without altering the source file.
Conceptually, the tool reads the binary XNB container, identifies asset blocks by type signatures, and decodes payloads when possible. It writes assets to common formats (textures to PNG, audio to WAV/OGG, fonts to TTF/OTF) and generates a per-file manifest with asset names, types, and sizes. Where decoding is not feasible, raw data with mime-type hints is exported. The process supports single-file and batch workflows.
Value and differentiation: it preserves data fidelity, supports multiple XNB versions, reports limitations, and avoids destructive edits. Advanced features include asset-type filtering, batch processing, and optional packaging (ZIP) of extracted assets plus a structured JSON manifest. Unique selling points are precise asset mapping, transparent reporting, and compatibility with downstream pipelines used in game development, research, and preservation work.
Use cases span asset reuse in remasters, documentation projects, and preservation of older titles. The tool is designed for developers, tool builders, modders, and digital archivists who need reliable, auditable asset extraction from XNB files without reverse engineering or code execution. It complements existing content pipelines and supports reproducible extraction tasks.
