And here's this glitch taken to the max using a TAS (in which a program is used to enter frame-perfect controller inputs). Apparently, a second controller is used to enter arbitrary code into RAM. http://tasvideos.org/4961S.html I don't really understand it, but it really blows my mind what some people think of.

The progression isn't particularly mind blowing, though. Once somebody notices a buffer overflow / register pollution of some sort, you note which area of memory it's executing and then reverse engineer how to modify that memory to execute particular instructions. I would expect a community like HN would consider this par for the course. That said, what's impressive to me is the amount of time and energy individuals…

Yeah, it turns out the link I posted is from one of the people behind the discovery/application of the glitch, so it really seems to be the logical next step if you know what you're doing.

And agreed on speedrunners! It's not something I could ever do myself, but it's one of my favorite aspects of gaming.

I don't know if you've watched The Dawn Wall; it reminds me of speedrun grinding IRL.

EDIT: I mixed up two retro gaming YouTubers. The below refers to Bisqwit, not Bismuth. His personal views aside, I hope you find Bisqwit's other videos interesting.

I really respect this guy as an engineer and a retro gaming enthusiast, but he has some videos explaining his personal irrational Islamophobia that really make me wonder about him as a person -- here's one of them: https://www.youtube.com/watch?v=xVxSAi4sueQ

That's absolutely insane. Manipulating the state of the game world so that its data maps to instructions to complete the game, and then glitching in a way that executes it. The only thing I'm not clear on: even knowing exactly what you're doing... how likely is it that you could pull this off in real-time? Did the player have to do this 10 times? 100? 1,000?

Speedrunners usually list their number of attempts in the top right corner of their splits window. In this case, it says 16/3904. My read of that is that this is his 3,904th total attempt at speed running this game (I have seen runners with attempt counts at over 40k). The 16 is probably attempt count for this specific session/stream, but I'm not as sure of that.

Say what? Watched the video and it did not even mention Islam?

I wonder how many of these people eventually go on to become developers and/or enter the (anti-?)security community, because finding and exploiting bugs in non-games also requires the same sets of skills.

It's a great video, that must have taken hundreds of hours just to animate, not to mention the research. That the author has opinions I don't agree with or are unpopular is another matter. I can have more than one thought because I'm not 4 anymore. This reflex to stigmatise and virtue signal annoys the freak out of me. Just enjoy the video.
