This reddit thing links to a TAS/ABC discord, wherein there are several related youtube clips being posted. I only just found this so I may not have things quite right, but it seems that the triangular platforms that rise and fall can be manipulated to rise very slowly due to a rounding error that works on Wii VC but not WiiU VC. This may take days (the initial strategy might take 8 days but someone mentioned cutting it down to 3).

On the decompilation of SM64:

As mentioned in that video, the completion of figuring out what all the functions and such do is relatively recent, and was not needed for most of Pannenkoek's work/all of Kaze's work. Most of what Pannenkoek does is based on STROOP, his way of monitoring and understanding RAM during gameplay, which was comparatively easier to sort out versus figuring out all the functions used to build the ROM.

IIRC, Pannekoek did use partial completion of the decompilation project a year or two ago to build an accurate simulator of the randomness in Tick Tock Clock to determine that a potential A-button challenge strategy which depended on insane luck would not be feasible/or at least would likely require days and days of waiting/manipulation.

Now that the decompilation project is done, I'm not sure what it's been used for aside from examine the compiler flag stuff and confirm that the bulk of the Dire Dire Docks lag is from the sub's collision detection being set up as if it were going to move, making it much more computationally intensive than needed. If there's other stuff being done with it, it hasn't been relevant to Pannenkoek's videos. Maybe the decompilation will be used to search for new ABC stuff or is being used to confirm that the strategy for 0 A presses should work the way people think, but I haven't kept up with the news/discord recently.

I also like skips that are found solely out of desperation, like the game just breaks down and happens to throw speedrunners a bone so they can do exactly the kind of thing they were trying to do

The Remote Lava Boost is almost an example of this. After a long time with only one required A press left in Mario 64, it seemed like every idea had been exhausted.

But then through dedication they were able to figure out that under ridiculously obscure circumstances, Mario can get flung in the air by lava without actually touching the lava. And the last A press is in an area with tons of lava! And a lava boost like that would get you enough height!

In other news, some guy is working on some new program that will display live head-to-head SMB1 speedruns on a single screen.

https://youtu.be/18fbp9H89Xg

Obviously, it can also display recorded runs, like this video shows. It seems he's also worked in a way to retroactively get the controller inputs from recorded sessions (even Miniland's, which was on a CRT).

This was really amazing to watch. Embedding so more people see it.

That is pretty insightful. Thanks.

The key phrase (often brought up in the education world) is "fixed mindset vs. growth mindset". It's talked about a lot with mathematics, but it's endemic across subjects, including video games.

I used to think I'd never be able to beat megaman/contra-style games because I'd tried some hard ones a tiny bit, failed, and gave up. I imagine a lot of people think they could never speedrun games when they just need to do some scaffolded practice.

Thanks for sharing this. It's nice to see a few more perspectives besides the Bismuth-SummoningSalt-TomatoAnus triad of speedruns explained.

There are lots of channels and videos inspired by SummoningSalt. Most of the ones have few videos, bad audio, or other growing pains, but I think Abyssoft is pretty good.

The other cool thing about Bismuth is that he'll soon be giving a talk on how glitch-hunting and such is basically a science.

Speedrunning Video Games as a Gateway to Scientific Endeavours
Speedrunning is the act of completing a video game as quickly as possible. Highly skilled speedrunners zip through levels at inhuman speeds, sometimes warping straight to the end credits. They set world records for millions of enthusiasts to watch in awe. But how does this black magic come to be? Behind the scenes, an entire community works together to discover new glitches and to further the understanding of these beloved games using a surprisingly scientific process of reverse engineering. In fact, science and video games become one and the same when trying to answer the ultimate question: what is the perfect speedrun?

For you/anyone who may not be aware. A full (120 star) playthrough of SM64 while blindfolded has been completed by Bubzia, who had been grinding towards that goal for something like 14 months.

I watched Dire Dire Docks and the last star (red coins in the wing cap area), but there are probably other good parts too:

This shouldn't languish in the Pokemon thread because it basically invented an interesting new type of TAS and delivered impressively. Basically, what if you specified the list of inputs like a TAS, but not the timing so you had to deal with all RNG with the same inputs?

quote:

This repository contains a list of inputs that theoretically will beat >99% of all Pokémon Firered games. There is no RNG manipulation involved, and there are no frame-perfect inputs required. The sequence of inputs is static, it does not require any information from the game. The intention of this list is to enable beating the game with no visuals/audio, or "blind and deaf".

In the spirit of Super Mario 64's "A Button Challenge", there was recently a TAS (well, a LOTAD) doing Ocarina of Time - All Dungeons in minimal C presses. Keeping in mind that it takes a C press to equip anything and C presses to play songs, it's tough to keep C presses low. Here's Twitch:
