OxyROMon vs Skraper

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.

Skraper is a free, non-commercial, non-profit application that adds metadata and media to retro-gaming software. It uses the community-fed ScreenScraper.fr database for artwork, screenshots, flyers, 3D boxes, and verified text information. The site advertises support for more than 200 systems and hundreds of thousands of media items and records. Skraper can provide EmulationStation metadata through Recalbox and RetroPie and fill LaunchBox game lists and images. Listed capabilities include game maps, manuals, Pad-2-Keyboard, Tips & Tricks, archive side-file filtering, and file renaming. A local cache, optimization, and multithreading reduce bandwidth use and increase speed. XML mixes can combine remote and local resources with positioning, resizing, rotation, color filters, and text or image layers. Windows may require .NET Framework 4.8.1. Linux requires the latest mono-complete package, with WINE kept up to date recommended. There is no native macOS build. ScreenScraper.fr anonymously records ROM or game names and checksums, which may be validated and added to its database.
