OxyROMon vs ROMSorter

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.

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.
