Lord Tom takes control of Super Mario Bros. 3 with help from TASBot and dwangoAC

[@walteralrus5364]

I remember this, when Mitch broke the TAS

[@waryspoop7031]

wait what? i didn't break the TAS! Kappa

[@NOT_A_ROBOT]

@@waryspoop7031 at the end, he softlocked the game in the map screen

[@hobbified]

4:40 it's because the HV power supply in the TV is a little bit weak... when the whole screen is white, the power supply voltage gets dragged down and everything is a bit dimmer. As more and more of the white gets replaced by black and green, the load on the power supply goes down, so the voltage goes up, and the greens get greener.

[@dwangoAC]

That's the most compelling reasoning I've seen yet, although I'm not sure why it also affected some capture devices. My PVM as expected also seems less susceptible.

[@hobbified]

@@dwangoAC in the case of capture devices it's probably because of automatic gain control on the input, which has a similar effect but more intentionally :)

[@Spiderboydk]

4:25 I think I have an explanation. Our colour perception depends a lot on the surrounding color, and since the initial green is mostly surrounded by bright white, so it appears very dark in comparison, similar to the checker shadow illusion. en.wikipedia.org/wiki/Checker_shadow_illusion

Hay dwango. I have a question. Is Rob needed for console verification or is he just for décor?By the way I really enjoy your work and GDQ segments.

[@cael5118]

I know how TASes work, but how does your R.O.B. TASbot work? Do you just have the ROB holding an Arduino that acts as the tas? How do the LEDs work?

[@evknucklehead]

The R.O.B. is a normal R.O.B., it holds the board that handles interpreting the movie files into button presses. Last I heard the board itself is a Raspberry Pi of some sort. Earlier versions did use an Arduino, but the Raspberry Pi is more flexible for what TASbot needs to do. As the board sends signals to the console TASbot is connected to, it also lights up the associated LEDs on the input display. I'm not entirely sure whether they have a separate output for the visualizer or if they peek at the controller output lines and interpret the results the same way the consoles themselves do, though.

Is the backdoor a legit in the game or just a whole load of clever ACE?

As soon as the pipe glitch is triggered, full ACE is achieved. While some elements from the game such as letters are used, what you see is the result of achieving ACE.

[@Faber0k]

After completion of a tas, how do you go back and make last minute changes without having to redo the rest of the run from that point? Or did you just mean last minute changes near the very end of the run?

[@dwangoAC]

Assuming you're talking about the changes we made right before the run was presented, we made them like any other changes to a TAS that don't cause a desync. For instance, if you're in an autoscroller you can go back and add flair by changing movement to be more exciting, such as adding a close call with an enemy as long as you ensure that things like coin count don't cause a desync later. For the post ACE section he was able to make other tweaks to improve it from an entertainment perspective.

[@MrKevan-qu5ny]

Wow I didn't know Mario could shinespark

[@dwangoAC]

Normally he can't. I still think that was one of the more impressive feats.

[@tallreversd]

I have a question: was this whole thing written in with the RAM values manipulated, or did Shigeru add this in secretly?

Why not whistle on the warp screen to go to world 8 pipe on warp screen as intended? @dwangoAC

[@dwangoAC]

You have to get to world 2 before you can warp to 7 and all of world 8 takes longer than using the pipe glitch in 7-1. This is the game end route MitchFlowerpower uses.

[@murilopauletti5249]

I am new to this, so sorry if the question is stupid. Is this a rom hack or it is in fact on the original cartridges? Is the Miyamoto message real?

[@ActionGamerAaron]

It's the original cartridge, but that message is not real. I believe they performed code injection via tool-assistance.

[@hysterheister0947]

So, if you assume a person could execute frame perfect inputs in the exact way TASBOT does, they would be able to execute any of this on console? Makes me think of using Cappy in the Grand Poo World run. How is that even possible?

[@dwangoAC]

Someone pressing buttons at superhuman speeds could in fact do this but for the really fast datarates like the music player they would do irreparable damage to their muscles. Also, their controller buttons might cause so much friction that it causes it to light on fire. I should do a proper longform answer in the style of XKCD's What If? series. That could be good fun.

[@hysterheister0947]

@@dwangoAC that sounds amazing. Count me in. Some of the TAS videos seem too obscure to be true, so I'd love to see something more in-depth. Thank you.

[@BusyCookin]

I doubt there is a short answer to this, but how it is that when the bit is playing, Mario’s sprite seems to get clip through certain objects? I saw how Mario partially clips into a block for example without having any sort of collision. Just fascinating to me, and I’d love to learn more about it, God willing.

[@Anafyral666]

Just enough speed with just enough precision?

[@evknucklehead]

Essentially what Anafyral said. If you touch a block in exactly the right way, it'll confuse the game and put you into the block instead of stopping you. Once you're inside a block, the game will try to force you out by pushing you to the right. This can be used to clip through walls or do wall jumps in a variety of Mario games that weren't meant to have wall jumps.

[@BusyCookin]

Thanks for the info guys! That's so insane how it works out like that. I need to research this more, God willing.

[@chamberkingston7609]

[@djflugel79]

When exactly is your code inserted and which memory is used for this code?

[@dwangoAC]

Per Lord Tom's notes at tasvideos.org/4961S.html under Bootstrapping Total Control he writes to $0098 within the initial loop itself. Basically, forcing the game to run his code in RAM every frame allows him to make changes that would otherwise be impossible.

[@rockonig7615]

Is it humanly possible to access this menu?

[@dwangoAC]

The menu doesn't actually exist in the game, we take over the entire console and program that menu by sending inputs through the controller ports at superhuman speeds. :)

[@mikewilliams6025]

At AGDQ didn't they admit to using an emulator? What was that all about?

An emulator is used to create the run but the final console verification is on a real console. I'm good about noting when an emulator is in use.

[@dwangoAC]

Echoing what others have said, this is an unmodified game and console (with the caveat that the video path has been cleaned up with an RGB mod).

[@Grachtnakk]

Can someone tell me how the game is altered like that? The dinosaur especially? I mean it's not a hacked ROM, right?

[@dwangoAC]

The pipe glitch allows us to force the game to execute arbitrary code just through the controller ports. The TASVideos submission notes have additional information.
