What RomVault is

RomVault is ROM management software for maintaining collections against DAT files on Windows and Linux. It scans files, identifies fixes, and rebuilds sets to match DATs; it can also detect duplicates, rename files, and verify hashes. DATVault is built into the program and lets users update DATs from cataloging projects with a button click. Without an access key, DATVault 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, but not RAR. Scanning and fixing default to Level 2. Its graphical interface runs on Windows and Linux using Mono, and separate command-line builds are available for both. RomVault is a standalone executable with no installer and needs write access to its directory. The free plan costs nothing, with core functionality and no ads or nag screens. Removed files move to ToSort, with an optional double-check deletion setting. Help and bug reporting are directed to the project wiki and Discord.
