Homebrew Homebrew on TLoZ: Majora's Mask??

if yellow9 do a OoThax why not MJhax? only i have Majora's for that i want the MJHax :F

They're two very different games.

But is The Legend of Zelda the 2 games -_-

Because they aren't encrypted the same way, OOT3D Hax came from a little exploit that you could find in the save slots, and by injecting a modified one, the game would assume that you're running that encryption, and also, because this is a 2011 Game, and so like TP, it is used as an entry point of hacking, Majora's Mask 3D fixed many of the issues that came from OOT3D, as well adding more support to users with N3DS, the encryption isn't the same at all, despite using some of the assets from OOT3D.

And finally, this remake was made since the 0 point, and so, the game has better security methods and it isn't going to recognize any save so easily, because it will most probably read as a corrupted thing, and again, is a recent game, with different mechanics altogether.

Yellows8++ LOL
In-Topic: He can't because he's found an exploit in the savegame that is encrypted with a very insecure method, as it's one of the first 3ds game
Save method for oot:

Repeating CTR Fail
On the 3DS savegames are stored much like on the DS, that is on a FLASH chip in the gamecart. On the DS these savegames were stored in plain-text but on the 3DS a layer of encryption was added. This is AES-CTR, as the contents of several savegames exhibit the odd behavior that xor-ing certain parts of the savegame together will result in the plain-text appearing.

The reason this works is because the stream cipher used has a period of 512 bytes. That is to say, it will repeat the same keystream after 512 bytes. The way you encrypt with a stream cipher is you XOR your data with the keystream as it is produced. Unfortunately, if your streamcipher repeats and you are encrypting a known plain-text (in our case, zeros) you are basically giving away your valuable keystream.

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.

It's not as easy as simply following that logic.
OoT 3D had an exploit related to the save slots.
And, if I'm not mistaken, OoTHax was released before Majora's Mask, wasn't it?

Seeing how Nintendo is following the hacks and exploits quite extensively, my bet is that such save exploit, if there was even one for MM, was patched during development of the game.

Even if it weren't, it doesn't mean that you can do the same thing from OoT right into MM, they're completely different games, and by extent, if there's an exploit for MM it would be handled in a different way.

Nice profile pic.

ye , yellow9 iz awsum

 

[Jwiz33]

Who is yellow9? Yellows8?
Just because SMW for the SNES was exploitable doesn't mean NSMBU is.

there's always the case of PSO but... that's an old story ^^

That's... a start, i guess?

Not really , more like preparations

But it's Yellows8, so we never know. Maybe he indeed has something.

Maybe , hopefully he has a 9.3+ Kernel + Time machine exploit

There was an exploit in the bank in MM3D but I dunno how it was achieved tbh, probably had to do with editing the rupees with the save file and causing the game to fuck itself, but I think it was the same as any other MM3D glitch/crash

are you, by any chance, thinking of https://github.com/yellows8/mm3d_re ?

(to anyone wondering: this repo contains in-game spoilers)

...I also just noticed someone linked to this earlier. I should definitely read...

I wasn't exactly referring to that but it does answer some of my suspicions. I'll link what I was talking about.
Edit:

Probably editing stuff in the save file to weird out the game. like always but I was sure yellows8 discontinued research on it for a reason, no? Maybe it's just my imagination.

 

[MAXLEMPIRA]

but he does!! there's actually one Majhax, is what I use for CFW on Sys 10.3 in my N3DS, how people can miss that!? :S I just don't understand :S

he's obviously a troll user with a troll thread trolling people xDD

If anyone looks that up, I hope they know the first link is twitch. Lol.
