Hacking Post your ideas regarding how to hack the 3DS, here

with the new r4i save dongle, can we expect some save game exploit?

Doubtful. Even if we can backup the saves, there's no way to modify them. There are checksums in the saves. And we still don't know of a point of attack for any 3DS game in its loading/saving code.

what is going on when we try to load some corrupted save?

Nothing, the game reformats the save. 3DS saves implement CRC checks now, presumably to kill off Action Replays.

lol it's explained here on how to decrypt the save..... http://3dbrew.org/wiki/Savegames

So how do you use this to decrypt a savegame on a 3DS? First off, you chunk up the savegame into 512 byte chunks. Then, you bin these chunks by their contents, discarding any that contain only FF. Now look for the most common chunk. This is your keystream. Now XOR the keystream with your original savegame and you should have a fully decrypted savegame. XOR with the keystream again to produce an encrypted savegame.

idk but i'm doubtful it's that easy, else, they would've done it already

But you can't change anything in the save because there are some unknown checksums.
ADD: Also that bug in the save file is fixed in newer games.

.... Real???

Why is the camera flipped in that video?

.... Real???

Have you guys read the youtube comments? I wonder why so many people commented that it works. I wonder if it could be real. So many people have said that Star Fox and Zelda work. I have been trying to crack the password, because I can't find it on the website they say it is on. I haven't had success with cracking it though. If anyone wants to crack it, you should post what you find.

Without even downloading it I can tell you its fake, and probably a trojan of some sort. Why? The video was posted in April. Don't you think if it really worked it would be posted all over the net, have been on the front page here, and be a sticky? Just think about it for a second. There are lots of videos like this, and they are all fake.

I wonder why all those comments say it works though? Is there a way to make hundreds of fake comments or something? Most fake videos that I have seen have mostly dislikes, but this one for some reason has mostly likes.

 

[Clydefrosch]

yeah, you can make lots of fake accounts, also, people might just be trolling each other here, like, comeon, lets all like this thing

A lot of people will go to those lengths on youtubes.
How it got 170k views and that like/dislike ratio is quite puzzling, it's just a reversed, muted video of someone playing Street Fighter IV.

So I totally didn't read up on 3DS security, but what if we have a cart, that takes a retail 3DS card for authentication, then using a timer, routes data from some sort of external memory as the game data? The authentication step is similar to what the original PassMe did.

You can filter comments, you know... ¬¬

Just found this:

I download it and it seems legit. Although I'm not sure.

It's a survey scam.

 

[Felipe_9595]

Ok, asked to a friend, he tested it, it worked. Anyone else can test it? i dont have a 3ds, but i found strange that the video had a lot of views + More likes than dislikes + people posting it worked.

And what is the password file?
