That's because that's how emulation works. When you get 20 fps it really means the game is running at 1/4 speedAnyone know how I can get F-Zero GX to have a good framerate? Is there any special settings that I can use? I have a MBP Retina 15" with 2.6GHz quad core i7 and 16GB ram. I only get 15-20 fps, and the game looks like it is running very slow.
