The Gaming Emporium is a curated archive and centralised directory of videogame-related projects, bringing together links to fan creations, preservation efforts, ports, and modern recreations. Visitors can browse its collection by category, game series, or genre, or explore popular, trending, rising, and recently added projects. Categories include decompilations and recompilations, open-source projects, fan games and homebrew, mods, ROM hacks, translation patches, ports, utilities, texture packs, guides, and virtual reality projects. The archive also features abandonware, preserved games, browser-based titles, and projects still in development.

Discovery tools such as Surprise Me and Hidden Gems help visitors find projects across the collection, while favourites can be saved locally without creating an account. The site invites users to suggest games and links, which are reviewed before being added. It also provides site statistics, an RSS feed, and instructions for installing the site on an iPhone or iPad home screen. Some projects may require users to provide their own ROMs; the site points visitors toward guides for dumping them.
