Wack0 (also known as "Slipstream") identified a "pialease nerf" stack buffer overflow for the game "Pokémon Ultra Sun," which can allow a payload to be executed, for the ability to perform speedrunning tasks or installing custom firmware if this is the case. The exploit appears to only work correctly with "Ultra Sun" at the time of writing with version 2.2.0; however, it is unclear whether older versions will work or if Ultra Moon might be supported.

To follow the steps in the guide, you will need both a first and secondary 3DS console with the same game installed, and both must have the same initial versions; otherwise, the exploit will not work. During this time, the exploit will run in the background on your second 3DS, and you must start a new game using Litten or Popplio as the starter. As you progress through the game, you will need to visit the nearest Pokémon Center. From there, access the Start Menu, select Quick Link, and connect. The first 3DS connected to the secondary will suddenly crash and reset. From there, load the save file and you'll be in the Champions Room to battle with a Level 100 "Darkrai", which is where the code-execution will begin.

This is absolutely fire. Reminds me of all those insane buffer overflow manips on N64.

Nintendo keeping up with their classic coding arts I see.

Incredible! Would love to see what crazy things people come up with.

I guess I'm having a hard time understanding--what implications does this have for speedrunning, per se?

The author used this example code to teleport to the Champion's room from a near-fresh save file, and entered the Hall of Fame in under 40 mins because of it. Of course this would never become an actual category.

In the future, I could see race communities using this exploit to skip intro cutscenes or start with a predetermined mon and stats.

I wonder if this will spike the price of pre-owned copies of Ultra Sun?
Quick check of CeX shows it's currently at £35 (Ultra Moon is actually more expensive at £38) - let's see where they're at in a month or two.

This is once again one of those cases where I'm just sitting here, bamboozled, at how the fuck someone managed to even figure out and find such a teeny tiny, overtly specific loophole/exploit/bug in the game. It's on the same level as some of the "out of map" exploits in some of the older Call of Duty games, it just truly makes you wonder what the hell people do with their time or how the hell they even find these exploits to begin with. Absolutely insane, but kudos to the dev for even finding something like this...

I already did, and found nothing. It may have but the article doesn't even mention it

@Scarlet Reading and logical comprehension, understanding grammar and making connections between words seems to be a skill lost time for many these days I suppose

 

[Sir Tortoise]

It's very cool just by itself, but I don't think this would be used for any serious speedrunning unless there was a way to set this exploit up without external tools. Otherwise you'd just have a homebrew application on your 3DS that immediately edits your save file to complete the game.

Hey I might not have reading comprehension or understand grammar but I...uh...what was the third thing you said?

You are capable of making a logical inference without having to read the exact words you're looking for and understand from context, right? Yes, it isn't outright mentioned that Ultra Moon is/isn't supported, but there are enough references made to it either directly or indirectly that you can make a logical inference and draw a conclusion by what is being said, no?

What has happened to people these days, all of the most modern educational systems and institutions in the world and yet so many fail at basic fifth grader reading comprehension. We're done for I swear...

Do you have any links to these n64 ones?

Do you mean like the OOT stale reference etc?

I'm not sure yet, but somebody with a copy might try it out for themselves.

Presumably not, since you have been easily able to hack any 3DS without the need of a physical game copy for years now.

I'd like to agree, but look what happened with that Alien game on PS1 despite there being many free alternatives available to run backups on that system.

I doubt the price would ever go higher. A lot of 3DS exploits don't need a game like Cubic Ninja to install custom firmware these days.

That's because of the shear number of scalpers who have watched Modern Vintage Gamer's video skyrocketing the price.
