ClrMamePro vs RomVault

ClrMamePro scans and rebuilds MAME machine sets, checking ROM, sample, and CHD files for missing, unnecessary, or incorrectly named files. Its Rebuilder matches input files against a database using hashes and size, then writes correctly named machine files to an output folder. The package includes a graphical interface and a command-line executable with Scanner, Rebuilder, and Dir2Dat functions. The tools can use a MAME executable's listxml or listsoftware export as a data source. They use 7z.dll for 7z archive support and can produce zip, 7z, or decompressed output. A suitable DatFile allows use with systems beyond MAME. There is no install wizard; users unpack the archive into a folder. Current builds run on Windows 7 and higher, while older documentation describes Linux use under WINE or similar. The software is freeware, and the copyright notice identifies Roman Scherzer as its author; he says he started clrmame(pro) in 1997. Incorrect settings or removal operations can cause data loss, so the author recommends backups.

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.
