| I totally have a 3DS game I want to rip open and maybe document if I find something.
But wait, do you need a 3DS with firmware 4.1-4.5 to be able to decrypt a ROM? I'm referencing the xor files. ____________________ Come on, you know you want to show support. Click the links below: >>Reasons for Operation Bluebird<< >>Operation Bluebird Facebook Page<< |

| My understanding is that it requires 4.5 or less, yes. |

Dammit. Already counted out before I had a chance to even look at anything. Nothing I can do but sit back for now then.  ____________________ Come on, you know you want to show support. Click the links below: >>Reasons for Operation Bluebird<< >>Operation Bluebird Facebook Page<< |

Originally posted by Xenesis I heard the same thing, but before that, I also heard you only need that to figure out the key for your game, and then you can use that with another program to break down files on your computer? I figure each game will have their own unique key, but that each copy will still share the same key. If this is true, we'll likely see a scene record of every key for each game, just like their checksums of proper dumps (right?). |

Originally posted by CeliceI wouldn't be surprised if decrypted ROMs started floating around the web regardless if every ROM image has a unique key or not. I expect this to happen, especially once 3DS emulators start to emerge because of this. It's just a waiting game for now. ____________________ Come on, you know you want to show support.

| Luckily, I haven't updated my 3DS in ages. Unluckily, that is because I lost it ages ago. I dunno if it was on 4.5 though.
I wonder if it possible to downgrade. EDIT: typo ____________________ New Super Mario Bros Beta Replica |

| Doesn't the 3DS have e-fuses for updates? |

| ^ E-fuses? I figured firmware updates were just flashing the NAND. Google tells me eFuses are a Microsoft and Motorola thing.
On 3DS decryption, let this be said because it took me forever to find this out: To generate the xorpad, you don't even need a flashcart capable of running 3DS roms. You only need a DS flashcart that can run on a 3DS. And it doesn't have to be a Gateway  .
(Same goes for 3DS rom dumping: Gateway's Launcher.dat can dump a 3DS cartridge to SD, and as long as it's the 1:1 original unmodified Launcher.dat, you can use a non-Gateway cart without bricking anything.) Note: I have not attempted any of this myself, this is all from info I've gathered awayways. e: vvv Thanks for clarifying that part |

| The Gateway Launcher.dat is used for cartridge dumping/NAND backup. There are alternate Launcher.dat files that generate xorpad files. |

Originally posted by ukueleh I'm sorry but can you please clarify this? You make is sound as if any 3DS, independent of firmware, can generate the xorpad as long as the 3DS can run the DS flash cart. That alone sounds strange to me since a DS flash cart can only run in DS mode to my knowledge. How can you possibly generate the xorpad in DS mode? Perhaps I am just missing something (Totally possible). ____________________ Come on, you know you want to show support.

Insert GW_INSTALLER.NDS into the DS(i) flashcart and boot on your 3DS console. 2. Run GW_INSTALLER.NDS from your flashcart's menu and let it install the DS profile exploit. 3. Return to the system menu once procedure has finished. 4. Insert Launcher.dat onto the SD Card that will be inserted into the 3DS console. 5. Navigate to Options > Other Settings > Profiles > Nintendo DS Profile and watch as your Launcher.dat runs!

| Ok, that ingredients and methods list makes sense. Thanks for compiling it, einstein95.
Damn, I really want to rip into a game too. Back to waiting I suppose. Nothing else I can do. ____________________ Come on, you know you want to show support. Click the links below: >>Reasons for Operation Bluebird<< >>Operation Bluebird Facebook Page<< |

Originally posted by ukueleh This will never happen. sspwn will only give user permissions, unlike the root permissions that running the launcher.dat does. This means that sspwn wont have access to the AES hardware needed to do the xorpad generation. ____________________ The more I type, the less gooder it sounds does. |

| Random thought, but if we can get those keys, doesn't that mean we can also make signed 3DS executables? (at which point the firmware version doesn't really matter, banned keys aside, but that can be worked around) |

| Oh, I guess they learned from the Wii =/ (where people figured out how to encrypt new executables) |
