‣ At 09:23, I mention you can go to any address with QDS/BBR tags, but realistically you are limited by the size of the structured ROM without the PAT tag.
‣ At 18:52, I mention Link's rock "despawning" with a camera exploit, but this is an oversimplification. The real way to get empty hands and abuse SRM has to do with setting up culling and loading triggers to unload the rock while it's in your hands, rather than "despawning" it.
‣ In general, multiple objects can be used to overwrite pointers in Ocarina of Time, but for the specific human-viable setup with the file select, LightNode SRM is used. This was glossed over in the video; more information can be found here: docs.google.com/document/d/1X...
‣ It's mentioned at 19:49 that the Japanese version of the game is required, but it is theoretically possible to use SRM to switch languages to the included Japanese within the US versions. This would allow for Japanese inputs on a US disc.

To honor a lot of people who have been super welcoming and kind since I started this channel, I've included a special credits sequence at the end of this video. Perhaps there's something after as well... 🤔
ACE is a very complicated topic, and there was quite a lot to cover with some specifics I might have glossed over. If this video piqued your interest, there are a lot of extras in the description, including some minor corrections!
I love you
no game is safe from ACE
U should've told us the time
@@itisliamhfjone22Give it a few years and we'll have PS2s running PS1 versions of Ace Combat ACE to run PS3 games.
awesome
The funniest thing about ACE in Ocarina of Time will always be that people keep using it to do ACE in other games. Shoutouts to the Paper Mario speedrun of course.
We'll make our own Stop'nSwop!
i was active in jcog's chat (she's the streamer who did stop'n'swop at GDQ) as ACE was discovered and the run was developed and it was insane to witness in real time
Now my question is, can you use ACE in the Super Smash Bros Brawl unlockable 5 minute demo mode for Ocarina of Time to do ACE and escape the SSBB emulator to modify Brawl?
@@Chrome166no, it’s separate from brawl iirc. Ace is possible in the 5 minutes though.
Omg asexuality in animal crossing 2024
Using OOT to execute ACE in Animal Crossing is like trying to break into a car with a more broken, fucked up and stupid car... and I wouldn't have it any other way.
So like breaking into a Lambo with a cybertruck?
Gotta find a use for it after all. Reusing is better than recycling
It's like using a legacy Win32 application to jailbreak a 64bit Windows OS :V
we can open this masterlock by using this masterlock.
@@satibelI got that reference.
The PAT tag is so funny. "Here's all the different tags they let us attach to a NES rom, and all the reasons it would be extremely challenging to achieve arbitrary memory modification with them.... oh wait, never mind, here's the 'make arbitrary memory modifications' one."
Either it was for debugging or patching the NES games like in Virtual Console.
@stgigamovement Correct. The included Legend of Zelda NES makes use of patching to function on AC’s emulator, but it’s actually done using another tag that has highly specific data for Zelda (SPE tag for “special”). I’m assuming the PAT tag was the general application for this to patch other games as well.
Presumably to not screw all of AC over if someone decided to ENGAGE RIDLEY
@@Wiimeiser That's definitely plausible.
@@Wiimeiser i absolutely must ENGAGE RIDLEY, MOTHER FUCKER
Ridley must die
i love how oot has essentially turned into an ace bootloader for many different games
Game Genie fell off
@@rompevuevitos222 we're on that Great Fairy cheat engine now!
I feel like I just watched the season finale to my favorite show
FOR REAL THE CREDITS ARE AMAZING (it oddly reminded me of the DS rainbow road from Mario kart 8)
My God, I know! I saw the notification for this video come up while I was on the phone with my boyfriend and I went, "Hunter! You magnificent bastard! You really went and did it! Holy crap!" My guy doesn't really understand any of this, but he still understood what a big deal it is.
Before we got off the phone, he's like, "go watch that video. I know you've been thinking about it. I've got one I've been waiting to see too." What an amazing time to be alive, seeing all the incredible discoveries that have come out about my favorite childhood pleasures really does feel like the season finale. Man.
@@Flexkid_ probably because that's a remix of Wii Rainbow Road in the background
@@UCRg_xCRyCLMhQXnGclhGxuA oh 🗿 I had a feeling, it sounded familiar
I felt that when seeing the credits lol
When you said 99% of the game is stored in RAM it made so much sense because I remember not owning the game as a kid and being able to play it for like a week by leaving my gamecube on after I booted up a friend's copy. He took it because he had to leave but I was stoked when it just kept working
That's awesome
thats amazing lol
I wonder what wouldve happened if you tried to play the minigames
Thats the best story ive read today. Amazing.
This is the things why i love computer in general 😂😂
@@UnaturalShadows probably would've just froze or went to black

and they're chilling like it's no big deal
The villagers just act like it happens all the time XD
@@shoadowolf Well, Boris certainly doesn't give two oinks about it.
IDEs have become obsolete, all coding will now be done using Animal Crossing and Ocarina of Time GC ports
funnily enough you don't even need to corrupt the instruction pointer in pokemon gen 1, there's just an item that executes code from WRAM directly
What's that? 😮
Knowing pokemon, i would be surprised if it is only one.
@@jacksonshoptaw4556 8F in red and blue executes code starting from the number of pokemon in your party
@@egon3705About half the glitch items in RBY share this functionality, 8F is just the most usable one.
Gen 1 Pokemon do be gen 1 pokemon
Extremely funny to hear how Gamecube OOT can theoretically be used to set up Animal Crossing ACE. This concept isn't completely new, as Paper Mario 64 got ACE and for a while, it couldn't do anything meaningful. It was then realized that you could use OOT ACE to set up memory, and then do a Banjo-Kazooie-style Stop 'n' Swop to Paper Mario, and then execute the OOT memory you wrote as Paper Mario code to save your file on the "The End" map, so loading the file again would end the game.
Really cool video, and I love how you acknowledged ACE as a serious security vulnerability on modern hardware.
Yeah the big problem with Paper Mario's ACE was while it was *theoretically* possible any way to utilize it was just too difficult. You could do the Stop'n'Swop payload with *any* other N64 game with ACE, but Ocarina of Time happens to be the one with the easiest ACE to perform. Lucky really.
WHAT
@@StarfieldDisarrayAbout a year after the stop n swap ace was found, we did manage to come up with a paper mario only method. It's however done in the volcano instead of goomba king

finally, Animal Crossing Exploit
Ha! Nice nickname for it.
Now that’s a ACE.
@@Emiko1 It certainly is!
“Oh Hunter, we know you’re an ACE in the hole.”
Hunter: “A what now?”
Ace the jock bird when he exists:
what does that phrase mean? i know its used in Hazbin Hotel to mention that Alastor is ace/asexual, but is it used elsewhere? what does the hole mean? is this a golf or a pool joke?
@@xymaryai8283 Are you trolling or genuinely can't can't see the joke?
The thing is, it's just a phrase "You're an asshole" but 'ass' replaced with 'ACE'.
I love how depending on the context ACE is either extremely cool or extremely worrying
Zelda ACE vs old emulator ACE. Also nice to see a fellow furry here
ACE: happy, despite being a little scary. meanwhile RCE.... never a fun time (Remote Code Execution)
i'm glad retro ACE exists since gamecubes can't connect to your internet and don't store, like, your credit card info on there or anything. kind of wish we still had stuff like that -- consoles on their own little islands.
Holy, the animations in the credits are phenomenal, so fluid and so cute, especially Isabelle! Please thank Wyvarie for me!
This is probably a long way off, but with how well understood this game is getting, I wonder if decomp progressing will allow for mods adding in features from later games into AC. A "Perfect" version with more options for paths, more pattern storage, easier access to the island without requiring a link cable, adding in a few characters, HD texture/font mod, more K.K. songs, more events, maybe fixing and adding in unused content or version/region-exclusive content, uncapping the 2030 limit, making the forbidden NES games appear in the shop, and more... If it was open source and made right, the community could create new little content drops every few months or so, so that the game feels magical again... Just thinking about something that nice makes me smile. I've always had a soft spot for the original and would love to see it get more of the little quality fixes that later games in the series got, but without the massive expanse in scope.
You’d be surprised at how far underway a lot of what you’re discussing is already. Behind the scenes, mods and quality-of-life features from future games are slowly being tested and added to the game.
The future is exciting! And thank you for the compliments. 🥳
@@Hunter-R. That's really exciting!! Thanks for sharing that, I look forward to hearing about it in your future videos! Now I'm imagining an even more robust real-time online multiplayer too...! Don't even tell me it's already being tested, it's a surprise haha
early nintendo games do be having at least one ACE exploit... don't look at the original pokemon gen 1 games there's too many to keep track
I swear, from what I've been seeing of the Gen 1 Pokémon games, they are held together by nothing but craft glue and wishes. It's amazing they work at all.
@@blakksheep736my favorite part about the gen 1 Pokémon games is that a lot of the most iconic glitches are only as harmless and easy to see as they are due to pure chance-if the translation error with tiles hadn't existed, the Cinnabar shore tricks wouldn't work, and if the first English translation of red/blue didn't have the data in the places it did Missingno could easily have been a crash-causing menace like it is in other versions of the game.
@@InnocentGuillotine and then there's yellow's missingno
They've found exploits for every mainline game up to Diamond and Pearl!
@@InnocentGuillotine the cinnabar shore tricks already doesn’t work without extra work in some languages due to being partially patched. You will go insane if you dive into the unexplored lands of different languages of Gen 1
Wake up guys new Hunter vid dropped. It's huntin time
I liked the part where he hunted all over the place
@@iiAwesomeJ real

horned hat... bug net... hunter custom design t-shirt... yeah, it's hunter time
Using ocarina of time as an ace setup game has also been done to do a credits warp in Paper mario, so its cool to see the same strategy applied to animal crossing to execute arbitrary code c: At least in this case it didnt rely on hot swapping a cartridge into the console before the ram got wiped x3
The biggest difference is that this one requires OoT as far as I'm aware, unlike paper Mario which only uses it because the inputs required to do it in game are too precise for humans
It would be crazy if Hunter announced he's turning over a new leaf with his channel at the end of this video.
IKR
He did.
Holy shit that credits sequence made me sob, referring to every person who, no matter how small or tangential, that helped this all come out, is so ridiculously cool. Losing my mind over how incredible that is and how much effort went into finding everyone.
Super kind of you to say! Working on the credits was super fun and Wyvarie's animations add a ton, as does Starmonized's rendition of Wii Rainbow Road. I'm very grateful to everyone involved!
I appreciate the heck out of it man. I have a lot of credits to do going forward and I don't know if I'll ever do it to this level of quality, but damn it, I'm gonna try. You changed my life and my perspective on this for the better, and I can't thank you enough for this.
Just two N64 games being bros.
Hunter R is Pannenkoek of Animal Crossing
Yes hes the pancake of animal crossing
@@mouthwaterin*The Dutch Pancake of Animal Crossing
That's... A bit of an exaggeration.
Pannenkoek is an absolute know-it-all when it comes to SM64, to the point he can make hour long videos that go in _very_ technical detail about the various quirks of the game.
Hunter is just giving surface level info about the game without going into too much technical detail.
@@T.T_CenrryTH The equivalent to this is probably Cuyler, who is outright decompiling the game, but I think he doesn't care much about making videos so he helps Hunter instead.
I’m not worthy to be compared to the GOAT. Like others said, rather than just talk about discoveries, pannenkoek actively works to TAS and break the game themselves as well - and has an editing style that’s far more fluent than mine.
I’m still passionate about the game of course, and I hope to dig my teeth into more personal contributions myself in the future. But, for now, I’m very far beyond pannenkoek’s achievements.
Awesome video!
Funny enough, Animal Crossing: New Leaf has an ACE exploit, which is also a RCE exploit. The function responsible for receiving packets for the games bulletin board can be used to send payloads to other 3DS consoles due to a buffer overflow trick. Such as giving them mod menus, editing their memory, basically anything you want really.
I learned a lot from this video, it's so cool what fans in the community are capable of!
Hacking their 3DS
@@NatetheNintendofan Yep. And a similar exploit is also possible in Animal Crossing: New Horizons, and my mod menu uses that to call functions on their system whenever they want to do certain things for themselves.
@@Bidziilla Really?
An RCE is a very serious issue, even if it's just a game console (also it sounds like the RCE it's in the 3DS, not GameCube)
@@Jason9637 It was in the 3DS and switch versions of the game. Likely ACCF too.
Excuse me whilst I scream at the algorithm.

Those credits slap 🔥 But anyway, thank you so much for making these videos! It's been great to see your channel all the way from the beginning. Can't wait to see you where you go next with new leaf! But no matter where you go I will be glad to be a part of it.
that credits scene feels like the end of a movie. It's really cool to see this channel grow and has certainly educated me on the really cool things going in the the Animal Crossing community and I'm really happy hear everyone involved was so passionate to share all these really cool discoveries here. Can't wait for new leaf. Amazing video as always congrats!!
The end credits animation was fantastic.
@@life-destiny1196 It ROCKED!!! Seeing Blathers, KK, Isabelle, a player digging up a fossil, a player dancing, running after a floating present with their net as if they could ever bring it down that way... awesome. Everything was just awesome.
Was watching all of your episodes together for my kids who also enjoy Animal Crossing. Love how you snuck in an easteregg regarding acnl for April 2024 as part of a letter you generated. Well done! Even if it's a month off, still impressive that you included it as a reference so early on and got as close as you did!
I appreciate it! I admittedly wanted to cover New Leaf before Nintendo shut the online servers down, but a few things got in the way. Since this video technically came out in April, I suppose I can just say the ACNL teaser in that letter was just for the announcement of a New Leaf video... >:)
23:10 ayy that's me!!
(for the record, all i did was fill in some villager names, so it's a pleasant surprise to be included!)
If you’re on the repo, you contributed! 🥳
I tried to include every one who has helped, no matter how small. Even if your work seems insignificant, even a first step like that is helpful.
Which villagers, and where?
sometimes i dont understand a word this guy's saying but his videos are so fun to just listen and vibe to. i love animal crossing and computer junk. thank you for making these videos T__T
got my horned hat... bug net... hunter custom design t-shirt... yeah, it's hunter time 😎
Extremely excited to see a longer video from you. I hope to see more!! I love how simply and easily you explain things & your video style is clean and sticks to my brain. I really like your narration as well - you have a good tone, cadence, and pace of talking. It's just right! The japanese stock images in this video are very cute as well.
that next animal crossing video seems really cool! theres a few technical aspects of new leaf that you can run into sometimes, especially with how the welcome amiibo update was introduced.
-the game keeps a backup of your save file pre-update, though it never touches it. you can go back to it if you play the game on another system without the update or otherwise force the game to run on the original system after deleting the patch (the home menu prevents you from downgrading for acnl), letting you effectively have two towns on the same cartridge.
-similar to this, the game keeps custom designs saved at the able sisters (not the ones you have in your menus) in a separate file separate to town data, meaning you can freely share custom designs between your two towns. super weird.
-the state the game is in on cartridge versions of acnl when trying to get the save data bonuses from a cartridge version of happy home designer is very weird. i dont think theres another 3ds cartridge game that has a feature that lets you eject the cartridge, put in a different cartridge, then put the original cartridge back in, and still be playing the same game all throughout. its super weird.
but since nintendo network went down not too long ago, i'm assuming this upcoming video has something to do with reviving the game's online features (online multiplayer, club tortimer, spotpass, dream suite, etc.). no news from pretendo about its progress aside from them saying they have all the old dream towns backed up, but i dunno, thought itd be cool to share some stuff ive personally come across. maybe theres something more to these mechanics?
Every video of yours hooks me in and explains things about games I would have never put a second thought into while playing.
Especially in this video, which you put so much time and passion into, I absolutely cannot wait for what's next, Hunter!!
You have consistently been getting better and better at your video production. I cant wait to see where this channel will go! I cannot wait to watch the next video, both in terms of editing production and because ACNL is my favorite game. Keep it up man!
This is a great video and channel in general! You deserve every view and subscriber you get and a million mor-wait… NEW LEAF???
Absolutely wonderful video! I do not think i have seen anyone explain ACE without prior knowledge requirements! This is now my go-to video to link people to if anyone asks me about stuff like this
Found your channel yesterday and was binge watching them all today. What a treat.
lucky you, i found this channel 2 months ago and have to wait for new videos
honestly this was amazing to watch, loved the deep tech stuff, your knowledge is crazy fun to hear about. More, more, more!
Seriously great video, and an awesome first impression to your channel!!! You made everything super understandable, and your visuals remained stylish and supportive. Really really happy I found this!!
Very kind words. Thank you so much!
Thanks for the videos! They've gotten me back into playing New Leaf again. Finally even got the toy hammer there. Very exciting to see you about to cover *my* Animal Crossing game in technical detail.
Beautiful video! And that credits sequence, chefs kiss!
ACE is the place with the video game hijinks.
awesome as always mate, been here aince you posted your first vid on the mp16 discord! cant wait for the next vid
Your best vid to date!! Loved the outro too, the credits animation was awesome!!
what a wonderful end to the beginning of this channel. very excited for new leaf now, and any further things you’ll cover. keep it up!
I just discovered your channel and you are absolutely a gem of a channel. Looking forward to knowing more about Animal Crossing than I'd ever thought I'd want to as I watch through your videos.
Thank you so much! I'm extremely grateful to have found an audience who finds these topics as interesting as I do. Your comment means a lot, and similar comments always make me glad I started this channel.
I did not expect a full visual explanation of SRM in OoT in this video. Amazing work!
Great video as always, and the credits animation/segment is just too sweet. While I love how the channel has gotten me interested in the original title, New Leaf is one of my favorites in the series so I’m super pumped to see where you go with that!
the credits animations were so good!
super hyped for the next video too! (i would be hype for any video you teased, but i'm extra hype for one covering one of my favorite games)
I love this video, definitely worth the wait, I'm glad I came across your channel a couple weeks ago!
This is hands-down one of the coolest videos I've seen in recent memory. Wow. I'm not someone with an extensive knowledge of programming, but you made it easy enough that even I could follow along! Thanks for putting everything into simpler terms. :^)
Another great one from Hunter! Cant wait to watch this through
How in the hell did you manage to make this video feel so momentous?! This video feels important, man.
I gotta say, on a personal note, I really must thank you for these videos Hunter, and the comfort they've helped to provide me in some dark times.
This goes to everyone who's helped make this channel a possibility, too. Thank you so much, sincerely.
I appreciate it, truly! This channel wouldn’t even exist without viewers like you, so thank you for the kind words. 🙂
I don't know how you do it, but every single Animal Crossing video you make is consistently interesting and informative. Keep up the good work! (Love the outro credits too)
Binge watched your channel over the past couple days. High quality stuff.
I love this stuff you do man. It’s so fascinating and ACE in particular is just wild to me. But honestly I’ve seen every video on your channel and love them all. I eagerly await your next uploads :)
This is actually fire, iv been watching you since your first video and my god you haven't disappointed me with a single video yet.
You are an extremely underrated channel. I love your content and the amount of effort/work you put into it! Great job as always!
Great video! Loved the end credits, and super excited to see what comes next for you.
amazing video as usual!! even if most things fly over my head, the way you explain them make them pretty reachable regardless. very excited for the next one!!
Omg the teaser at the end! I've learned so much about ACPG from this channel I cant wait for the next chapter. Thanks for making my nerd brain happy as always Hunter :) Loved this video!
Truly amazing AC content! Thank you for another very informative and entertaining video. Can’t wait for the next. Keep it up
This is one of the channels that was great with the first videos, and has stayed that way. This has been one of the more enjoyable channels, and I hope it can stay that way. Gl with the RUclips channel, and everything else your doing, stay safe, thanks for making content!
A slight technical note: There is, strictly speaking, no difference between executable code and data. In fact, many advanced programming techniques rely on manipulating code _as if_ it were data (this is called 'metaprogramming', because you're programming the act of programming).
This is part of why buffer overflows lead to ACE sometimes. Computers do not know the difference between instructions and data, so if you can write data to a spot where instructions would be stored, that data gets treated like instructions. You can also do the same in reverse--IIRC, the static screen effect in _Metroid Prime's_ game over sequence is actually the game's compiled code, read out as if it were texture data.
While this is still true on modern systems, there's been a LOT of work done to keep you from accidentally using data as if it were code--and more importantly, to prevent people from doing that to machines they're not supposed to have access to.
This was for sure a wonderful video! As a programmer myself it's crazy to learn about how these exploits work and the dedication of their associated communities.
Super hyped for your ACNL videos btw!
Brilliant Video! Extremley excited about the next one.
A thing im really interested in is if you could technically use this to speedrun animal crossing? Like a new "OOT%" category lol
Some additional technical context for those interested! The reason the PAT tag can only write to 0x80000000 thru 0x807FFFFF is because that's the size of RAM on the N64. This same PAT tag exploit is usable on the N64 version albeit you can't do nearly as much since you're limited to 32K of space on the controller pak data (still a lot though!)
Additionally, when we overwrite my_free, we *could* encounter a similar issue as to trying to overwrite code directly. The GC also has a data cache but the caches only store the most recent commonly used addresses in them. Thankfully due to my_free's infrequent referencing, it doesn't get cached. That's a small piece of the puzzle that James and I spent a bit of time figuring out lol...
It was really fun to mess with this back in 2018! I wrote a fully working hex editor for use in game among other neat little proof of concepts!
Great video as always Hunter :)
Such a cool discovery, and both yours and James’ posts on the topic were very thorough. Thank you!
For those who are interested in additional technical information, I do highly suggest checking out Cuyler’s blog and posts on this topic (linked in description). If there’s anyone who’s helped the most with my video topics, it’s definitely Cuyler. Just like piggybacking off of my_free, you could argue I piggyback off a lot of Cuyler’s work when it comes to discussing Animal Crossing. 🐐
great work as always! while coding stuff goes straight over my head, it's cool to see the process. glad i found your channel :)
There should be an ACE no-skip category of speedruns for various games. Imagine how it cool it would be to see a runner essentially modding the game in real time but not being allowed to skip levels.
Great video man! One of the most convoluted topics in animal crossing modding, and you covered it very well. Based on that ending i’m looking forward to some new leaf content!
I wish I could like this video more than just once! ❤ This was a great video, and it’s clear you’re proud of it! I can’t wait to see more videos.
loved this video. Thank you for explaining ACE so well!
Incredible video and great subject ! The next video is going to be awesome, hope to see the evolution of the channel !
Banger video all around, great job to everyone involved 👏👏
Excellent video!
I love how OoT is the ever expanding gateway for ACE in so many games
its insane to see how far you've come from your first upload and im looking forward to more!
Thank you so much!
good to see that you did decide to cover some acnl stuff
also the credit sequence was very cool
Killer introduction. Great overview of ACE!!
Oh man so exciting!
I been here since the beginning, Thank you Hunter!
wow! this is very impressive! i love to see the modding community doing cool things with 20+ year old games to do cool things with other 20+ year old games... also congrats on 40k subscribers!
its incredibly impressive how much hunter’s videos have improved in such short time
THE GOAT HAS UPLOADED A LONG FORM VIDEO LETS GO
either youtube glitched or i'm stupid bc i couldve sworn i was subscribed to you! your stuff is so interesting to my animal crossing obsessed brain and im super glad i ran across your channel lol
The credits animations are absolutely fantastic! Amazing work by Wyvarie!! (Starmonized's Rainbow Road cover is exceptional too)
That credit sequence was amazing!! I’m sure a lot of work got put into it :D (and the TEASER!) It’s like a TV show!
killer explanation so far, I loved watching the old ones people did over time; this is a fun piece of history you're documenting
That was an incredible explanation of ACE. I’ve known it existed but never bothered to try and learn how it works and the way you described it made it crystal clear. That was awesome
OK, the part about using OOT to write the exploit onto the memory card was awesome! Great video :)
The credit animations are so cute!
Excited for the next video too aaaa
I love the little drawings included in the editing, such a cute and fitting style
I love Irasutoya.
I really hope this leads to a surge in AC GCN modding popularity. I feel like this game's graphics and vibe are absolutely perfect for an entirely new generation of mario 64-style crazy romhacks. People have already shown that they love designing environments and storylines in their towns in the newer games, and it would be so great to finally apply that creativity back to GCN. I'd absolutely love to see one of those classic new leaf horror maps done in GCN using tools like this.
Wait but at the very end 👀the best game???
Very excited for your next video! And thrilled at this one. Every time you post a video it makes me want to pull my gamecube out (two problems: 1. I don't have a tv, and 2. My wireless controller broke years ago and replacement ones are so expensive 😭)
YEAAA THIS WAS GREAT!! I love love love this kind of content so much, and the next video is on my fave in the series!!!!! Can it get better than this
Can’t wait to stay watching this channel for the next few years until eventually he makes it to an animal crossing game I actually own
In all seriousness that new leaf stuff is big news, so excited to see it. It definitely felt like we were slightly running out of glitches on the original. Keep it up. Love it
Not seen all this yet, but just wanted to say that the OOT footage you're showing at the start isn't ACE, it was a prank pulled at an event. Many ACE glitches have a limited payload, which does limit what can be done unless it can be leveraged to enable larger payloads to be executed.
There's still some great ACE out there though, I think Mr Cheeze has some good examples.
[EDIT: I was wrong. Triforce% uses ACE to stream models and music from a PC connected to the N64.]
What are you talking about? Triforce% wasn't a prank, it was real, so why would you think that?
Its real and actually uses arbitrary code execution thru tasbot. they have an actual patch file on their website but use ACE at the event
The jokey parts of the playthrough at GDQ were intended to have prank-y vibes (IMO, from the way they did the describing at the event), but they were achieved via ACE exploits set up in real time. To my memory, the initial payload was essentially "listen to the player 2 controller inputs and interpret them as code to execute on the fly" (which IIRC was why it was apparently finicky and required the human runner doing the playing to do only specific things lest the game potentially crash; if it were just a modded OOT cartridge that likely would have been able to be mitigated); part of the reason that was the instruction is because the payload would be too small to do it all otherwise. The player 2 controller input was TASbot sending instructions faster than a human would likely be able to, which was why it worked (even the Twitch chat was fed through that port) but the bot can only feed so much down the line so fast.
That's why they reiterate late in the block for the game, when the nature of the run becomes obvious, that the cartridge is unmodified, because it's a stock OOT cartridge.
@@themightypikachu8119 Yeah, I went and read more about it and it uses ACE to do the following (from their website):
Triforce% is a hybrid RTA/TAS "speedrun" of Ocarina of Time which uses Arbitrary Code Execution (ACE) to install a set of data loaders in system memory, enabling arbitrary assets (scenes, objects, music, etc.) in the game ROM to be seamlessly live-patched from the host PC.
So I was wrong about it not being ACE, I just remembered it not being pure ACE (as the assets are streamed in from a PC, not built as code and executed)
So glad you showed Triforce% as an example! Such an INCREDIBLE showcase that deserves way more attention
i'm so excited to see the new leaf video!!! it's my favorite animal crossing game and one of my favorite games ever. also great video!!
