Skraper vs WolvenKit

Skraper is a free, non-commercial, non-profit application that adds metadata and media to retro-gaming software. It uses the community-fed ScreenScraper.fr database for artwork, screenshots, flyers, 3D boxes, and verified text information. The site advertises support for more than 200 systems and hundreds of thousands of media items and records. Skraper can provide EmulationStation metadata through Recalbox and RetroPie and fill LaunchBox game lists and images. Listed capabilities include game maps, manuals, Pad-2-Keyboard, Tips & Tricks, archive side-file filtering, and file renaming. A local cache, optimization, and multithreading reduce bandwidth use and increase speed. XML mixes can combine remote and local resources with positioning, resizing, rotation, color filters, and text or image layers. Windows may require .NET Framework 4.8.1. Linux requires the latest mono-complete package, with WINE kept up to date recommended. There is no native macOS build. ScreenScraper.fr anonymously records ROM or game names and checksums, which may be validated and added to its database.

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.
