Mod it with Free McBoot, use HDLoader and you won't ever have to use the disc drive again, so yes.

(I got lucky with the network adapter though, GameStop rarely has them for $15)

Yes, i added a few funny details, but you have to reach the firmware through Pc-3ds communication.If you witnessed a real hacking in your life, you should know that.That's the only way to fully unlock the system.


Riiiiiight, because the Wii was more or less hacked without a computer using a pair of tweezers. (Read up on the Tweezer Hack.)
That hack led to the Twilight Hack, which again didn't require any communication (it just delivered a payload that caused a buffer overflow in Epona's name, allowing execution of unsigned code).

That won't help. As pelago said, what you see is what you get. Stuff that goes onto 3DS memory never touches the SD card. We don't even know what's in the eShop download specifically, so we can't remark on what's on the 3DS and what's on the SD card. (Not to mention that trying to access any temporary files during that time will lead to nasty file system errors.)

As usual, I'm going to wear black and eat this that day.

I was not discussing comparing save formats, just whether the programming itself could be compared.
Also, save game exploits will not work, as we have mentioned many times before; the 3DS does checks on saves to ensure they have not been tampered with. There is no doubt that a simple port will have a very similar save structure (this will vary per game, of course). However, it is irrelevant as we have no way of running said exploit if we were to make one.

There's no need to be so defensive. SuzieJoeBob brought up the idea of comparing cross-platform games which, in my mind, is someone less technically minded suggesting that if we can find an exploit in a game on a console that's already hacked we might be able to exploit the same vulnerability on the 3DS. You shot that suggestion down saying that the SDKs were different so that wouldn't be possible, and that's why I said what I said. Regardless of what you are or aren't discussing, I said what I said in response because I thought it was relevant.

I also said editing saves wasn't currently possible, as you kindly elaborated for me. However, that doesn't mean it won't ever be possible; all the checksums and hashes are in the save file, so the algorithms could possibly be reversed. That being said, I don't think a save game hack will be the first exploit for the 3DS. I think it's more likely that a hardware hack will lead to a software hack (like on the Wii).


I apologize if I sounded defensive. I should be studying for some tests and I'm not really in a good mood right now.
Also, permanent save game exploits will most likely not happen until we get some CFW going. You are correct on the hardware hack probably being the first thing to happen.
I would also like to point out that checksums/hashes are designed to be irreversible. We can't simply "reverse" an algorithm, as there is not enough information to reconstruct data from a hash. If you're talking about reverse-engineering the algorithm, it appears that it's also based on a stream cipher, which makes this relatively easy to break if we have access to the 3DS's pseudo-random number generator and the initial seed used with the stream cipher.
Anyway, because we do not, it's not practical for the time being. Unfortunately, it also looks like Nintendo is able to change the type of save encryption used, according to 3DBrew (the scheme changed at firmware 2.0.0-4). Meaning that being able to encrypt our own saves will only work until the next firmware update.
