Hacking 3DS Homebrew Channel!

How would you go about only encrypting part of RAM? Wouldn't discerning between certain types of data and only encrypting some be a total resource drain?
Either you encrypt everything in RAM or you encrypt nothing. In this case it's, with 99% probability, nothing.
The PS3 also doesn't encrypt RAM, afaik. So it isn't unheard of in modern consoles.
In general it isn't a problem if the rest of the consoles security works. But being able to watch and edit RAM makes it much easier to find flaws in that security.

...the RAM itself is not encrypted, I tried to explain that to you. RAM simply contains data, which can be encrypted or not. RAM is Random Access Memory, it's simply used to store data which is necessary at a given moment simply because it's designed for fast input and output, that's all there is to it.

Just out of curiosity, does anyone know how region-checking is done?

It's probably in the header, as per usual, as there is no physical difference between the cartridges, nor a technological reason for this lock.

 

[totalnoob617]

so if you can edit the header then what is to stop a flashcard like the crown was supposed to be,one that doesnt rely on an exploit but is just a 1:1 card for running commercial roms? i would think some team has used his work already to build their own ram dumper ,

 

[Chaos Rush]

Why would you want a flashcart over a softmod?

A flash cart would be the only way to play commercial games since the SD card slot is not as fast as the cartridge slot.

What about emulators for lower-tech systems (like NES, SNES, Genesis/MegaDrive, etc.)? Will that be possible with an SD card?

On a side note, I know that many people will tear me apart for saying this, since there are lots of people on GBATemp that support piracy, but I personally hope that it will remain impossible to pirate 3DS games. I really hope the 3DS won't become a sickening pirate-fest like what happened with the DS.

(oh and I don't consider emulations of really old systems as piracy)

If it goes by the header, that must mean that in the ram, somewhere, the value of either the system or the card is transferred. Perhaps, through monitoring of the ram, we can play God and toggle what that data is concerning the region lock and perhaps we can bypass that lock.

Yeah, with stuff like that the ROMs can be loaded into RAM and done from there.

Surely if it was a matter of a single variable then it would be done by now. They should focus their search on exploits and then bother with the less important issues.

 

[Rydian]

Well if it was a single variable it might still be stuck in with other encrypted data, and even if it was a single byte, if it's position in the stream isn't concrete that might make finding it abit of a hassle.

And then there's the expalantion of "maybe the guy doing it doesn't give a damn". Not everybody cares that much about playing imports.

 

[Ghostyis40]

Even with a video what makes you all think it would be any more valid, ppl put fake stuff up on Youtube all the time and it looks real when done right! Like with Wii U and its plethora or rumors I am going to keep waiting until I hear that the 3DS has an official way to run homebrew!

One of the main reasons people want the system exploited is so the region lock is removed. I'm pretty sure it'll be easy once we can figure out what is happening in the ram of the system.

Region lock is just an excuse, people really want to play 3DS roms on it. Just that some are honest about it and others use excuses but in the end, they all run to buy flashcards or install softmods. I know on which side I am

 

[TheCasketMan]

I want a PS3 emulator!!!

well let's not go that far
i'm sure there are some people here who want the region lock to be gone[that being the top priority]and prefer japanize games but also want to play pal/ntsc region games
but when the option of piracy is right in front of your face, you ARE going to make use of it for sure

 

[kthnxshwn]

I'm almost certain that only a handful of people here want the 3DS to be hacked in order to bypass region locks. I mean, it sounds good now, but when that game you plan on ordering and waiting a month to arrive leaks online two weeks before the Japanese launch...we can talk then.

Plus there's the fact that even if neimod did disable the region check using his setup, it would be 100% useless to 99% of people who would want it. Without a setup like his, you can't edit RAM, so just knowing what value(s) to change in RAM, and where, would be useless. Unless he REALLY wants to be able to play imports (on a 3DS that is mostly dismantled and so probably not exactly a joy to play games on), it would be a complete waste of his time to even look.

I want a PS3 emulator!!!

Im sure it can be done in terms of programing, that stuf can happen, its who would do it.
I remember, the dingoo doesnt have much power to emulate a PS1 dicent, but a programer had the apropiate skill to program a PS1 emulator for DIngo and its flying the emulator.
I remember users saying that PS1 emulator for dingo would be "IMPOSIBLE" News | Dingoonity.org - The Dingoo Community

If someone out there has the apropiate skill, I would like a PS3 emulator. It CAN be done.


although I would e more than happy with Gamecube emulator.

pretty sure that was sarcasm. The 3DS (afaik) would have trouble emulating the N64. Let alone a PS3.

wait does this mean we hacked the 3ds?

"We"? What part did you play in this exactly?

Eh, there isn't even a PS3 emulator for Windows yet, and you think we can make one for the 3DS?

wait does this mean we hacked the 3ds?

We only hacked the RAM, which means:

• We can edit the RAM in real time(? Neimod didn't say anything about limitations)
• It may make finding 3DS exploits easier

However, you would need to build a RAM board like Neimod's...

I think he meant the 3DS community...
