ROMSorter vs verifydump

ROMSorter detects and renames ROMs and other games, with tools for archives, duplicates and file checks. It can zip files, convert supported archive formats by extracting and recompressing them, or unpack archives into a folder. Identical files can be moved into a subfolder named after the original file. A catalog stores file names and hashes for later checks that files have not changed. The program can create DAT files for other ROM manager apps and rename single-file games using a supplied DAT file. It converts BIN/CUE or ISO files to CHD and can extract CHD back to BIN/CUE using chdman. Other tools include building one-game, one-ROM sets from Parent/Clone DAT files with region priorities, sorting Everdrive folders by starting letter, generating M3U playlists, and batch IPS/BPS patching. The current ROMSorter release is for Win-x64 only; its Librarian command-line companion is available across platforms. Both require .NET 6. Linux and Mac Librarian users need an appropriate MAME chdman build for CHD commands. It is free, MIT licensed and provided without warranty.

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.
