ROM Librarian vs RomForge

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.

RomForge is free, open-source desktop software for managing ROM collections in the OfflineList DAT ecosystem. It scans ROM folders and matches files to DAT entries using CRC32, then reports statuses such as Verified, Missing, Incorrectly Named, Wrong Archive Type and Untrimmed. Users can rename ROMs to DAT-expected filenames, re-archive between ZIP and 7z, and remove GBA or NDS padding. The application supports multiple DAT files and can update them from configured URLs. Its cache re-hashes only files that changed, while game-list status persists across restarts. RomForge is a modern rewrite of OfflineList and remains compatible with community DAT files. It reads OfflineList XML DAT files, which users supply, but does not currently read the No-Intro/Logiqx format. Supported systems are macOS on Apple Silicon and Intel, Windows x64 and Linux x64. The macOS app is signed and notarized; Windows downloads are ZIP archives and Linux downloads are TAR.GZ archives. The project uses the MIT license.
