Nearcade vs ROM Librarian

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.

ROM Librarian is a free, open-source desktop application for managing retro gaming ROM collections on Windows and Linux. It renames batches with regular expressions, showing previews, handling filename collisions, and supporting undo. Its DAT rename tool matches ROMs with No-Intro or MAME DAT files using CRC32, MD5, and SHA1 hashes. The application compresses ROMs to ZIP or 7z and extracts both archive types. It converts CUE/BIN and ISO disc images to CHD; Windows includes chdman, while Linux users must have chdman in PATH. Renaming can update EmulationStation or RetroPie gamelist.xml metadata, with restoration through undo. Multi-disc detection creates M3U playlists. Duplicate detection uses SHA1 or MD5 and preferences for region, size, and date. A Linux command-line interface supports scripted operations. The MIT-licensed project credits RobotWizard.
