Hacking 3DS Hack: "We hacked it"

[Yatashi Strife]

ok how about this will street pass work on a un-updated 3ds

most likely but idk. i believe that data is saved to the system but i dont know for sure, i dont think that it being updated or not will get in the way. only thing that will probably be affected is the loss of eshop from not updating.

I accessed SP before I updated my 3DS a few days ago.

You know man, I am a programmer, Foxi and Pro2man are programmers too.
Would you question a doctor's diagnostic?
Probably no, because he have spent his life studying about that.

But let's suppose you do,
if you want a second professional opinion,
and after seeing a new doctor's with same diagnostic you're still not convinced,
If you see a third doctor, and he gives you the same diagnostic,
do you still think this diagnostic is wrong?

That's basically the same case.

I'm sorry, but that is ridiculous. Let's say that those three doctors are all from the same office. And they're all telling you that it's healthy to drink 5 liters of gasoline a day. A smart man would still not believe them, and instead investigate what the majority of doctors believe, not three.

While I trust that Foxi, Pro2man, and VMM are posting, what you are saying is ridiculous. It's always perfectly understandable for somebody to ask what the source of their information is. Infact, you should be asking why these users are so automatically skeptical, not questioning why they don't blindly accept what others are saying.

same here so yea it should work if its 3ds mode.

OBVIOUSLY KNOWS WHAT HE'S TALKING ABOUT GUYS SO THE DS HACK IS FAKE OKAY LETS JUST GO HOME

Let's put it simply.

Insert cartridge into 3DS.
3DS boots the ROM off of the cartridge.
3DS loads save data from save flash into memory.
You play your game.

The cartridge does not boot itself. I do not have a stack of free-energy powered 3DS cartridges sitting on my desk running 24/7 because they're booting themselves.

So say you have a savegame exploit. The save flash is rewritable, or else you would not be able to save your game. So you make a hacked game save, encrypt it, and use something like the R4i Save Dongle or NDS Adapter+ to write it back to the cartridges save flash. Then...

Insert cartridge into 3DS.
3DS boots the ROM off of the cartridge.
3DS loads save data from save flash into memory.
You play your game.
And with the hacked save:
You play to certain point where the modified part of the save data is accessed.
Stack overflow, crash system
Load custom code
Get some sort of higher level access and execute unsigned code. Hopefully.
Your SD card is not a part of the equation. Period. If you don't believe me, go load up any cartridge based 3DS game and remove your SD card before it loads, your save game will still be there. Or go ahead and take it out while you're playing then save your game. Your game will still save.


You're incredibly dense.
ANYWAY
I'll have to keep an eye on what happens with this. Would certainly be easy to do as a cart based exploit, my 3DS is a few SM revisions back, as is my brother's. If it turns out I can't update it or else I lose the hack, then so be it, I'll buy an XL in addition. I do need to update it and redownload all of my Ambassador games though.

Edit - if re-writing and loading modified saves weren't possible, people wouldn't be able to use Pokesav to get Pokemon with custom stats in their legitimate cartridge based games. But they do, somehow. http://cyclods.wikidot.com/homebrew:pokesav

You are absolutelly right,
but with all the discussion that have been going on,
it looks like nothing will stop Dr Pikachu in this one-man cruzade.


I suggest that we stop discussing it and pretend it never happened
before the mods hunt us down with warnings and bans, and the topic gets locked

Hahahaha. Hahahahahahaha. Hahaha. Ha. Haha.

You just want the bitch-fest back dont you? you can tell me

 

[Chary]

Shhh, don't mention about how many chips are in a cartridge.

No, I just saw an incredibly flawed argument and I had to say something.

 

[nukeboy95]

soo if it yellow8's pic than why its not in 3dbrew?

 

[Sicklyboy]

Shhh, don't mention about how many chips are in a cartridge.

Imagine the commotion if someone finds a cartridge with 4 chips.

OHSHI--

we changed subject not only because it was flawed, but also irrelevant, but now, you sir are stirring the shi-

Perhaps VMM used the argument of "authority" here, but I sure as hell haven't - I directed Dr Pikachu to resources where he will be able to extend his knowledge about how game cartridges work - to Wikipedia. I also directed him to 3DSBrew, which features detailed information about the cartridge and how it's built and interfaced with.

As for the skepticism, it comes naturally to anyone that it's not the game booting itself, it's the system booting the game - it's the cartridge that piggybacks on the console, not the other way around. The game (or its portion necessary for its function at any given time) is copied to RAM from where it is executed, assets are accessed via the Data Buses. That's how cartridges work, that's how they always worked.

All the cartridge memory controllers (embedded on the silicone or not - it's same difference) do nowadays is handle the addresses the 3DS requests - the days of mappers built into the cartridge that the console actually interfaced with are over, and have been for quite some time.

In any case, this is all off-topic and perhaps it's time we return to the subject proper, which is the exploit itself.

Your SD card is not a part of the equation. Period. If you don't believe me, go load up any cartridge based 3DS game and remove your SD card before it loads, your save game will still be there. Or go ahead and take it out while you're playing then save your game. Your game will still save.

We only discussed SD-related issues because someone said the 3DS has no SD access when executing a game stored on a cartridge, which is not necessarily true - it's not the cartridge that governs it but the firmware, and if the firmware doesn't have such a limitation then it's entirely possible to use SD-based assets.

Also, last post I make in this train wreck:

Well, the time embed didn't work. 1:32

In other words, "I'm not a part of your system man" "Welcome to the real world jackass"

My sentiments when.

Yep. I'm going to bed.

thats it

We gave him all the sources he needed and more,
and of course, when I said that, I'm obviously considering that these doctors aren't from the same office.
That would be extremely stupid.

But I guess you're here just for trolling

News are all over twitter

 

[ieatpixels]

So many f***ing useless posts in this thread. I just want to know more about the exploit. What it can actually do.
So he edited a save game which ran some code off the SD card which only edited the text for the error screen.

He says it can't use any of the "gfx service" so who knows if this would be able to run actual homebrew or anything meaningful.
This actually reminds of the text edit another hacker did, this one;

Which ended up being useless.

There's still hope for this hack, but you guys seem to be jumping to conclusions.
