Hi Cmoses and thanks for the great comments.
I chose Maximus Arcade (MA) as my front end due to it's slick look and simplicity. It is super easy to configure. It was worth the $25 registration fee for lifetime support.
I'm pretty sure MA supports LED configs such as the LED Wiz. I'm not sure if they support emulators as I've never tried it myself. However, the good news is the creator of the Frontend (Mameseer) has just purchased a LED Wiz and is working on stronger support for it.
As far as the control panel layout, I'm not quite sure it MA supports that, but it probably does, as it support pre and post launching of external programs. Again, I haven't tried it myself so I cannot confirm.
For your MA exiting question, you should assign a key to exit in the preferences. I set mine to the "End" key. (Escape is default and works with MAME, but it does NOT work for all emulators since Escape is not the default key for every emulator). Once you set it to the "End" key, you simply assign a button on your panel for the end key. Mine is a dedicated admin button, but you could always set your for a shifted button to save room.
As far as the video, I am sad to say that I cannot share it. I created it for RetrowareTV.com and technically they own the rights to it. He let me use it on my cab (modified with my name). As for my original video (the blue one), I once shared it but the guy I gave it to butchered it to suit his needs. So unfortunately, I'm very hesitant to share again. I hope you understand. However, my skin is downloadable on the Maximus Arcade website and I created a title screen with audio that you can use.
Hope this helped and good luck!
