Igir vs WolvenKit

Igir is a free ROM collection manager for scanning, organizing, filtering, patching, and reporting on game files. It can find DATs, ROMs, and ROM patches, including files inside archives, then organize ROMs with consistent names. Users can filter duplicates and unwanted ROMs, create multi-disc playlists, and apply patches in batches. Reports can show which ROMs are present or missing for each console, and Igir can generate fixdats for missing ROMs. For arcade collections, it can build or rebuild MAME sets by un-merging, splitting, or merging them. Documentation includes configuration guides for tools such as Batocera, LaunchBox, RetroArch, OpenEmu, and RomM. Igir runs on Windows, macOS, Linux, and other operating systems supported by Node.js. It is available as a downloadable executable or through npm, Homebrew, and Scoop. Every installation option requires a baseline understanding of command-line interfaces. The project describes its defaults as non-destructive and says it does not make network requests beyond those requested by the user, including usage or telemetry requests. Igir is licensed under GNU GPL version 3.

WolvenKit is a free, open-source modding tool focused on Cyberpunk 2077 and REDengine 4. It can browse, extract, modify and repack game files into archives for use in the game. The Asset Browser previews meshes and textures from base-game or user-generated archives. Its RTTI-based File Editor reads and saves REDengine files, handles in-place buffer data, and converts game files to human-readable JSON and back. Project Explorer organizes files and opens source assets such as blend, PSD and XCF files. Asset conversion tools cover listed texture and model formats, with Blender one-click imports for shaded Cyberpunk meshes. Stable and nightly builds come through GitHub releases. Windows 10/11 64-bit and Linux are supported, although Linux compatibility is described as unstable and not guaranteed. The latest .NET 10.0 runtime and x64 architecture are required.
