	Pannenkoek2012: "The random bit flip hypothesis shown in this video is just the current leading hypothesis. Before that, it was the ceiling seams, and before that the bob-omb/explosion/coin, and before that landing on the platform/wall at the same frame. Frankly, a gamma ray happening to flip a particular bit seems a bit far-fetched to me. It's completely possible that some in-game mechanic treats the height float like an integer and decrements it, thus decreasing that bit from a 1 to a 0, in which case the glitch would be reproducible, and the bounty would be awarded to the person who submits that. The bounty is not rewarded for hypotheses as to what caused the upwarp, otherwise the bob-omb or ceiling hypotheses would have "solved" it long ago."<br>		Pannenkoek2012: "The random bit flip hypothesis shown in this video is just the current leading hypothesis.

== August 4, 2015 ==
pannenkoek2012 put a $1000 bounty on the glitch. It was thought to be an unknown hangable ceiling glitch. The hypothesis was later superceded by the random bit flip hypothesis. (See August 5, 2015) 
 
https://www.youtube.com/watch?v=X5cwuYFUUAY 
 
== August 5, 2015 ==
The random bit flip hypothesis was introduced in this video, labeled the current leading hypothesis. 

https://www.youtube.com/watch?v=X5cwuYFUUAY (description) 

pannenkoek2012: "The random bit flip hypothesis shown in this video is just the current leading hypothesis. Before that, it was the ceiling seams, and before that the bob-omb/explosion/coin, and before that landing on the platform/wall at the same frame. Frankly, a gamma ray happening to flip a particular bit seems a bit far-fetched to me. It's completely possible that some in-game mechanic treats the height float like an integer and decrements it, thus decreasing that bit from a 1 to a 0, in which case the glitch would be reproducible, and the bounty would be awarded to the person who submits that. The bounty is not rewarded for hypotheses as to what caused the upwarp, otherwise the bob-omb or ceiling hypotheses would have "solved" it long ago." 

Following that was an ECC discussion.

Some confusion occurred after users used the VR4400 manual to assume ECC exists in VR4300 too. (VR4300 is the processor used by the N64) It was later discovered that VR4300 didn't have ECC.

"However, this is a function used by the VR4400 to

(26) and cache error register (27) do not practically operate. These registers are

"Because the VR4300 does not check data by using a cache parity, a parity error
