It offers ROM and title management, as well as some basic in browser emulation of those ROMs. > Version 1.7.0 and later contain user authentication, and can be exposed to the internet. However, it is recommended to not expose the server to the internet if you're not actively using it remotely, or if you have alternative means to access it remotely like a VPN. > While we do our best to stay on top of server security, if you expose the server to the internet **you do so at your own risk**. ## Screenshots    ## Requirements * MariaDB 11.1.2+ (preferred) or MySQL Server 8+ * These are the database versions Gaseous has been tested and developed against. Your mileage may vary with earlier versions. * MariaDB is the preferred database server, while MySQL will continue to be supported for existing users (they should be interchangable). * Note that due to the earlier database schema using MySQL specific features, moving to MariaDB from MySQL will require rebuilding your database from scratch. The "Library Scan" background task can be used to re-import all titles. * ffmpeg * Internet Game Database API Key.
