ROMba

ROMba is a command-line tool (and WEB shell) for the management, and collection of ROMs and Dat-files within the Linux and Mac OS X environments.

While its core functionality is similar to tools like RomVault and clrmamepro, ROMba takes a unique approach by storing ROMs in a de-duplicated way, and allowing you to "build" any set you need on demand.
