RomCenter is a free, open source application for managing and organizing your ROMs (Read-Only Memory). It is designed to help you keep track of your ROMs for various classic gaming consoles, such as the Atari 2600, the Nintendo Entertainment System (NES), the Sega Genesis, and more. It allows you to easily create and maintain lists of your ROMs, tag them with metadata such as game title, publisher, and release date, and preview artwork associated with them. RomCenter also allows you to keep track of your gaming progress and achievements, as well as identify and remove duplicate ROMs. It is available as a desktop application for Windows, Mac, and Linux, as well as a website.
The latest discontinued version, 2008.20, released in July 2008, can still be downloaded from gamebrew.org.
