I made a mistake in my StarFox review once. I had originally thought that the SuperFX chip was something built into the SNES system but unused for a time while they were still perfecting the software for it. I don't know where the heck I got that idea. Not more than a day later, someone had pointed out to me my mistake, that the SuperFX chip was a chip used in the game cart, not the system, and I fixed it right away.
