Just want to say a bit about
GameEx. GameEx is by far the very best MAME FrontEnd available on the web! Tom Spiers has really put together something that is tailored to the customer. Through his website and attached forum, he takes requests and updates the software to include just about anything you might like with it. Additionally, a user known as 'Headkaze' has authored some accompanying software to allow each user to create their own themes to further customize the FrontEnd.
I have a MAMERoom Ultimate Arcade II cabinet that I put together and customized and I was able to tailor a very specific FrontEnd using GameEx for it.
I also have a media PC attached to my 42" Plasma HDTV and I have tailored a complete media platform for that as well. Here are some of the features that you get with GameEx (It is free BTW with a nag screen that goes away with a small donation):
GameEx is a graphical DirectX based front-end for MAME, Zinc, Daphne, PC Games, and all command line based game emulators, along with being a complete Home Theatre PC solution. The original goal was for it to be used on Windows Media Center as a plug in for playing games and for Arcade Cabinets although will run on Windows 98SE, ME, 2000, XP, and Vista. If you have Media Center and don't need a games plug-in, GameEx still adds additional features including Internet Radio, News Reader, DVD's on disk, and Karaoke.
