GameEx 18.61
GameEx provides you with a complete Home Theatre as well as a front-end for MAME, GameBase, Daphne, PC Games, and all command line game emulators.
GameEx initially started as a Home Theatre and has expanded into much more. The standard version supports most emulators, Media Center Plug-In, Arcade Controls (X-Arcade, Slik-Stik), Native Widescreen and HD support, full touchscreen, and tablet support. It also has full integration with GameEx Arcade, adding thousands of flash games, jukebox support (play while playing games), video player, DVD player, picture and slideshow viewer, internet radio, a newsreader, and more. So, you get the idea; it is much more than a gaming front end.
GameEx offers a premium version with more features that you can read about here.
