Hacker News Stories and Comments
All the comments and stories posted to Hacker News that reference this video.⬐ rockbrunoI love these, they are always really impressive. They've done the same with Ocarina of Time in the same event[0] to inject entirely new levels into the game on the fly and even give it Wi-Fi capabilities (sort of)⬐ elldoubleyew⬐ 7373737373I don't understand how they got a network connection to load in the chat on an unmodified console. Was the TASBot connected to the network and pushing the messages via controller inputs? If so that is pretty insane.⬐ raldi⬐ birracervezaYes; the four controller ports allow a total of like 60 bytes per read.⬐ gfaure⬐ NobodyNadaActually, they progressively inject faster bootstrappers and end up with about 4.8 kB/s: https://youtu.be/qBK1sq1BQ2Q⬐ VyseofArcadiaI'm pretty impressed all the stuff they patched in the game at just 4.8 kB/s. TASBot was not active for all that long.⬐ bdonlan⬐ raldiTASBot was only controlling controller 1 for a short time, but it remained connected to controllers 2-4 for the entire run, giving it time to download additional content as the showcase was going on.⬐ VyseofArcadiaAh, I was under the impression that it had stopped. That makes more sense.But still about 60 bytes per read, an insurmountable limit.Yes, TASBot is controlled by a PC connected to the network, and was pushing chat messages over the controller port in addition to ACE payloads.Everything is on GitHub, so here's the code that was injected into the game to read commands from TASBot over the controller port: https://github.com/triforce-percent/triforce-percent/blob/01...
That is pure insanity, the in-engine custom ending with BotW shading is mind blowing.Recommended: Pokémon Yellow Total Control Hack: https://www.youtube.com/watch?v=p5T81yHkHtI⬐ ComputerCat⬐ s3r3nityBrings back so many memoriesAwesome to watch, and I recommend listening to the technical explanations if you have time.I love some of the YouTube videos coming out recently explaining not just this exploit, but also some of the Zelda: Ocarina of Time applications of ACE, including a new category called "Triforce%," in which speedrunners use a program to input millions of inputs that essentially code a _new game_ within the _original, un-modded cartridge._
I feel like I've learned more about assembly and architecture concepts from those videos in the past year or so than I had reading any other book over the course of my career.

Sad to see.⬐ randomhodler84⬐ SkeuomorphicBeeCalling people by their preferred pronouns isn’t politics, it’s not being an asshole.⬐ thebitstick"Oh no, someone prefers being called by a pronoun they weren't born with, the humanity!"Grow up.
⬐ minimaxirWhat exactly is the politics you're referring to?⬐ skyylerI have two guesses:When runners are being featured, their preferred pronouns are displayed on screen.
Their events were remote during the pandemic, the recent event last week required everyone attending to wear masks.
⬐ danparsonsonThe end of civilisation as we know it!⬐ skyylerWon't someone think of the transphobic gamers and their needs???Just to add some context, arbitrary code execution in Super Mario World is nothing new, it has been known since 2014. There was a tool assisted demonstration at Awesome Games Done Quick 2014 [1] where they inject a pong and a snake game using a TASBot (a robot controller that replays input scripts to the console). And in 2016 a streamer performed it manually to inject a flappy birds game [2] (this second video is really good, he goes into detail of the process).So, what this newer demonstration brings is the use of the known arbitrary code execution capabilities of "Super Mario World" to help finish all 5 games in "Super Mario All-Stars + Super Mario World" as quick as possible.
⬐ CSMastermindDisclaimer: I didn't watch the linked video but I did watch some of Sethbling's older videos about the All-Stars exploit which I assume this post is in reference to.I think the bigger exploit here is not only the Super Mario World ACE but the Mario 3 save file exploit.
