OxyROMon vs RomForge

oxyROMon is a free, cross-platform command-line tool for organizing and archiving ROM collections. Written in Rust, it checks files against known-good databases and supports console, computer and arcade systems through Logiqx DAT files. Commands can import, validate, check, convert, export and purge ROMs, as well as create M3U playlists for multi-disc games. It is designed for original and lossless formats; exporting to lossy formats leaves the lossless files untouched. Collections can be sorted by region or in 1G1R mode, while arcade sets can be grouped by BIOS, parent and clone. Settings are stored in SQLite with global options and per-system overrides. The documented database sources include No-Intro and Redump for consoles, and MAME or FBNeo for arcade systems. An optional server provides a GraphQL endpoint and web interface for browsing collections, managing settings, and importing ROMs and DATs. The server defaults to loopback, but URL imports can reach hosts accessible to it, so exposing the server beyond loopback requires care. No-Intro DAT handling checks for updates but does not download the DAT files.

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.
