RomVault vs WolvenKit

RomVault is ROM management software for maintaining collections against DAT files on Windows and Linux. It scans ROMs, identifies available fixes, and rebuilds sets according to DAT definitions. Duplicate detection, file renaming, and hash verification are included. The built-in DATVault can update DAT files from ROM cataloging projects, although access without a key is limited to official MAME listxml DATs. Patreon supporters receive full repository access and a unique key. RomVault handles uncompressed files, ZIP, 7z, and CHD archives; RAR is not supported. The graphical interface runs directly as a standalone executable without an installer and needs write access to its directory. Separate command-line builds are available for Windows and Linux. Scanning and fixing default to Level 2. Removed files move to ToSort, with an optional double-check before deletion. The free plan costs nothing and includes core functionality without ads or nag screens.

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.
