Info

@Normmatt has created a way to run B9S .firm files from bootrom via a DSi Flashcard and a magnet! This works on every 3DS on any firmware version.

For installation without a PC, user @TheCyberQuake has created a pack which will automatically install B9S and copy over essential starter homebrew from the flashcard's SD to the 3DS's. This will mainly be used for PC-less B9S installations. If you have a PC with you, use 3ds.guide. Read more here: https://gbatemp.net/threads/481141/

How does this work?

This works because of a flaw in the bootrom. Before the bootrom boots the NAND, it checks to see if Start+Select+X is held down, and if the shell is closed. If these requirements are met, it will boot an NDS cartridge from the bootrom. This give that cartridge bootrom access. You might be wondering how you'd hold down buttons while the shell is closed, and why you need a magnet. If you put a magnet in a specific spot on the 3DS, it will go into sleep mode. Using this, you can boot the NDS cartridge with the buttons held down while in sleep mode! Using a reflashable flashcard, you can boot B9SInstaller using the flashcard, and easily install it on your 3DS.

The 2DS doesn't need a magnet since a switch puts it to sleep instead of a magnet.

What does this mean?

  1. Any 3DS model on any firmware can be hacked with minimal effort
  2. You can unbrick any 3DS model from any type of brick.
    - Remember, you don't need a NAND backup for this. Just do a CTRTransfer.
    - This does not apply to MCU bricks.
  3. Even consoles with fried NAND, or even the NAND chip physically removed, can use this
This is incredibly impressive stuff, and will most likely be released soon! edit: now!

FAQ

Q: Can Nintendo patch this?
A: Nope! Not without a new hardware revision.

Q: My flashcard is blocked by my firmware! Can I still use this?
A: Yes! The flashcard blacklist is not enabled on the bootrom.

Q: Why can't this work with my flashcard?
A: The installation requires you to flash NTRBoot to the flashcard's nand. Most DS flashcards, such as the original R4, have a ROM, which is not flashable.

Q: Can I install NTRBoot on my flashcard without another 3DS system?
A: If you can run NDS roms on your 3DS with it, then yes. If it's blocked on your 3DS version, then you'll need another 3DS system to use it.

Q: Will my 3DS flashcard work?
A: No, only the NDSi flashcards listed above.

Q: Will any other flash cards work?
A: Only the ones listed in the OP. However keep in mind that flashcards such as the DSTT, Supercard DS2 and R4 SDHC Dualcore are planned to be supported in the future.

Q: I tried to do this with my cartridge and it didn't work?
A: It doesn't work with regular DS cards.

Q: Can I unbrick from a ____ brick?
A: Considering the card has access to the bootrom, yes! This can unbrick any brick (except MCU), unless you've taken a knife to the motherboard.

Q: Can I install B9S on the latest firmware with this?
A: Again, since the card has access to the bootrom, you can do this easily! Just plug in your flashcard, boot up using the magnet and button combination, and install.

Q: Does this work on the New Nintendo 2DS XL?
A: Yes!

Another tidbit of info: the 2ds doesn't need a magnet since a switch (not that one, that one) puts it to sleep instead of a magnet.

Front page when? Also, this is really epic!

Let's wait until it's released since there's no telling when that will be.

    LLMs can be run on cpu anyway but it's quite slow
  • BakerMan @ BakerMan:
    Have you ever been beaten by a wet spaghetti noodle by your girlfriend because she has a twin sister, and you got confused and fucked her dad?
  • Psionic Roshambo @ Psionic Roshambo:
    Lol
  • Psionic Roshambo @ Psionic Roshambo:
    I had a girlfriend who had a twin sister and they would mess with me constantly.... Until one chipped a tooth then finally I could tell them apart.... Lol
  • Psionic Roshambo @ Psionic Roshambo:
    They would have the same hair style the same clothes everything... Really messed with my head lol
  • Psionic Roshambo @ Psionic Roshambo:
    @The Real Jdbye, I could see AMD trying to pull off the CPU GPU tandem thing, would be a way to maybe close the gap a bit with Nvidia. Plus it would kinda put Nvidia at a future disadvantage since Nvidia can't make X86/64 CPUs? Intel and AMD licensing issues... I wonder how much that has held back innovation.
  • The Real Jdbye @ The Real Jdbye:
    i don't think nvidia wants to get in the x64 cpu market anyways
  • The Real Jdbye @ The Real Jdbye:
    you've seen how much intel is struggling getting into the gpu market
  • The Real Jdbye @ The Real Jdbye:
    and nvidia is already doing ARM
  • The Real Jdbye @ The Real Jdbye:
    i don't think they want to take more focus away from their gpus
  • Psionic Roshambo @ Psionic Roshambo:
    Yeah I think Nvidia s future lays in AI GPU acceleration stuff if they can get that going it's going to be super interesting in the long term
  • Psionic Roshambo @ Psionic Roshambo:
    AI assisted game creation might become a thing
  • Psionic Roshambo @ Psionic Roshambo:
    At least that's something I think would be pretty cool.
  • Psionic Roshambo @ Psionic Roshambo:
    Don some VR glasses and gloves and talk to the computer and paint entire worlds

    "Now we need a spring fed river flowing down the north side and add some wild life appropriate for the biome"
  • Psionic Roshambo @ Psionic Roshambo:
    Many TBs of assets and the programming of something like that is going to be tough but I think it's something we might see in 20 years maybe sooner
  • The Real Jdbye @ The Real Jdbye:
    @Psionic Roshambo AI assisted game creation is kinda already here, there was recently that AI that can turn any 2D image into a fully modeled 3D object, it's not perfect, but it's a starting point, beats starting from zero

  • The Real Jdbye @ The Real Jdbye:
    before that there was one to generate a fully modeled scene from a 2D image
     +1
  • The Real Jdbye @ The Real Jdbye:
    but most recently, there was one that actually generates a working unity scene with terrain and textures already set up that you can import right into unity, that's a huge time saver right there

  • The Real Jdbye @ The Real Jdbye:
    and using LLMs to generate NPC dialogue and even dynamically generated quests is something i'm sure is already happening

  • The Real Jdbye @ The Real Jdbye:
    will just take some time for games made using those things to be completed and released
