This was posted on November 2013 and I just read it December 2017 this happened to me as well and I'm curious if others have come across it?
"I remember a long time ago; at least 1991-1992. I found this bizarre bug in Super Mario Kart for the SNES. I was watching a replay of my performance on Ghost Valley 2 and about halfway through the replay, my racer was turning and running into things erratically: obviously that WASN'T what happened when I played. And then a minute later, the replay showed my racer stopping, I wondered if it would continue driving but didn't and then I was able to take control of the racer while in replay mode.
What kind of craziness did I stumble across all those years ago??!!"
