JRomManager vs RomVault

JRomManager is a free Java ROM manager for organizing and checking ROM collections. It works with MAME and Logiqx DAT files and can also import data from the MAME executable. Its tools scan, fix, and rebuild split, non-merged, or merged sets. It supports ZIP and 7z archives, TorrentZip, RAR4 and RAR5 decompression, and multi-volume RAR and 7z decompression. Checks include full or on-demand SHA1 scans, MD5 for older DAT files, CHD, and Software Lists. One important CHD limit: verification reads the header for MD5 or SHA1 but does not hash the CHD data. With MAME linked to a profile, its viewer can launch games or software marked available. Batch tools include a directory updater, torrent checker, and archive compressor. Desktop packages are listed for Windows x64, macOS x64 and ARM, and Linux x64; it can also run on an OS with Java 21. Server mode serves a web interface. Simple Server lacks encryption, access control, and DDoS protection; Full Server offers accounts, access rights, and TLS 1.3, but is experimental.

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.
