MAME Smart ROM Sorter vs OxyROMon

MAME Smart ROM Sorter has no write-up on Specifiction yet; its figures are above.

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.
