ROM Librarian vs verifydump

ROM Librarian is a free, open-source desktop application for managing retro gaming ROM collections on Windows and Linux. It renames batches with regular expressions, showing previews, handling filename collisions, and supporting undo. Its DAT rename tool matches ROMs with No-Intro or MAME DAT files using CRC32, MD5, and SHA1 hashes. The application compresses ROMs to ZIP or 7z and extracts both archive types. It converts CUE/BIN and ISO disc images to CHD; Windows includes chdman, while Linux users must have chdman in PATH. Renaming can update EmulationStation or RetroPie gamelist.xml metadata, with restoration through undo. Multi-disc detection creates M3U playlists. Duplicate detection uses SHA1 or MD5 and preferences for region, size, and date. A Linux command-line interface supports scripted operations. The MIT-licensed project credits RobotWizard.

verifydump is a free command-line tool for checking compressed .chd and .rvz disc images against Redump Datfiles. It converts each image into the original format described by the Datfile, adjusts the result to Redump conventions, then checks it against the Datfile. Users provide a Datfile, which can be zipped, followed by image files or folders containing them. The tool says it does not modify user files and stops checking an individual image after finding an error. CHD checks require chdman and binmerge, both available in the system PATH; RVZ checks require DolphinTool in the system PATH. Some Redump cue metadata cannot be represented in CHD. Users can provide original cue files with --extra-cue-source or ignore cue mismatches with --allow-cue-file-mismatches. Verification creates temporary converted files and deletes them afterward; the project suggests a RAM drive for frequent checks or large collections to reduce SSD writes. Windows users can use the offered executable, while Linux and macOS users can install through pipx or another Python package installation method. The package requires Python 3.10 or later and below 3.16. The project directs bug reports and questions to GitHub issues.
