I KNEW it was something stupid and simple. Thanks for the help.

Whoops, my mistake. I meant "START Menu", not "STAR Menu". I get a white "MAIN MENU" instead of the MintyPi menu shown in the FAQ.

Instead, I get a white background menu that might be the standard RetroPi Menu. Either way, it does not seem...
