Pegasus is a graphical frontend for browsing your game library (especially retro games) and launching them from one place. It's focusing on customizability, cross platform support (including embedded devices) and high performance.

A modern retro-gaming setup: Instead of launching different games with different emulators one by one manually, you can add them to Pegasus and launch the games from a friendly graphical screen from your couch. You can add all kinds of artworks, metadata or video previews for each game to make it look even better!
