Arcade Manager vs RomVault

Arcade Manager has no write-up on Specifiction yet; its figures are above.

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.
