I'm at a loss for what to do. I'm trying to run Pokemon Emerald with VisualBoyAdvance 1.7.2, and I can't get the game to start. I'm using the "Open..." option, selecting the ZIP archive for the game, and all it gives me is a blank screen with "loaded battery" at the bottom left. What do I do? Like I said, I'm brand new to this, so I'm sorry if I've said something stupid.
