Well, it's better than VBA, since it doesn't just come up with a white screen, whenever I try to load a ROM.
I'm playing Pokemon Emerald, and when I go to the Rusturf Tunnel, the whole screen is foggy and white. It's not a problem because it's a short area. I'm running into this problem again once I go into the Lavaridge Town gym, I can't see anything but trainers. Help?
