RomM is a self-hosted application for organizing and playing retro game collections through a clean, responsive web interface, ideal for emulator enthusiasts. It scans and enriches your game library with metadata from IGDB, Screenscraper, and MobyGames, supporting over 400 platforms, and fetches custom artwork from SteamGridDB. You can play games directly in the browser using EmulatorJS and RuffleRS, share your library with customizable permissions, and manage games (view, upload, update, delete) from any modern browser. RomM supports multi-disk games, DLCs, mods, patches, manuals, and custom tags for filtering. It integrates with Playnite and muOS, and displays RetroAchievements. RomM is an alternative to RetroAssembly. In this step by step guide I will show you how to install RomM on your UGREEN NAS using Docker & Portainer.
