RomVault
What it is
RomVault is ROM management software for maintaining collections against DAT files. It scans ROMs, finds fixes, and rebuilds sets; it can also detect duplicates, rename files, and verify hashes. Built-in DATVault lets users update DATs from ROM cataloging projects with a button click. Without an access key, DATVault is limited to official MAME listxml DATs; Patreon supporters get full repository access and a unique key. RomVault supports uncompressed files, ZIP, 7z, and CHD, but not RAR. Its graphical interface runs on Windows and on Linux using Mono, and separate command-line builds are available for both systems. It is a standalone executable without an installer and needs write access to its directory. Scanning and fixing default to Level 2. Removed files are moved to ToSort, and an optional setting adds a double-check before deletion. The free plan includes core functionality without ads or nag screens. The project directs users to its wiki and Discord for support and bug reporting. Its comparison page estimates approximately 1 GB of RAM per million files managed. The public RVWorld repository describes itself as the home of RomVault 3.8 and is licensed under Apache-2.0.
