Nearcade vs OxyROMon

Nearcade is a free, open-source, self-hosted platform for playing local co-op games over the internet with friends. A host runs the game, while viewers join from a desktop or mobile web browser without installing a client. Streaming uses WebCodecs or WebRTC and peer-to-peer connections. Hosts can allow gamepad input, raw keyboard and mouse, or keyboard and mouse mapped to a virtual gamepad; mobile viewers get touch controls and a virtual joystick. Sessions can use private Cloudflare or Zrok tunnels, or appear in the public Nearcade Arcade lobby. Public Arcade sessions are limited to 80 minutes and require a verified tunneling provider. A host needs Node.js 18 or newer and Python 3. Linux also requires PipeWire and the uinput module, while Windows gamepad support requires ViGEmBus. Linux is listed as production-stable; Windows and macOS are experimental, and macOS lacks gamepad support. The project is published under GPL-3.0 and provides setup, usage, API, and VPS server documentation.

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.
