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!

Yes, but i heard something about that R4 SDHC that costs a half than R4i RTS will be compatible and i want to know if that's true.

I think that i've been clear this time. Thank you.

http://www.nds-card.com/ProShow.asp?ProID=507 do you mean this? or is it not on nds-card?

i wouldnt recommend getting that card bro

 

[annson24]

Don't get what this has to do with unsupported flashcarts, it IS supported, it is just not finished. I asked what would be more likely, and i got a smartass response, don't try to play it cool. you act like a smartass, i act like one back.

You're still not getting it don't you? Hehe. How dense can one person get? Well being stubborn as you are, however you put it, you're still asking us the magical question. But! Think as you please, if it'll get you sleeping through the night then go ahead.

Ps. My magical ball still isn't responding, sorry.

What is with this "dense" shit?

I'm not talking about when my shit would arrive. It's a simple hypothetical. If i were to order a card, what would happen first. I don't know how you don't get a hypothetical question. Stop with this shit thinking that having an attitude is funny when someone asks a simple question.

 

[gamesquest1]

Yeah the point is your asking a question that nobody really knows the answer, it's like asking If I go to get a bus and my friend catches the train who will get somewhere first?

Seeing as there is no "eta" on either option any answer would just be random guess which is kinda pointless you can guess yourself and have a 50% chance of being correct

If you had already ordered the card, it would have been shipped right now and you'd have your answer Lol. Instead of speculating, just order it or wait for yours to be supported by checking the github now and then. For reference when I ordered my card from NDS-cards, it arrived in 9 days and I'm on the East Coast of the U.S. Besides, the card (R4i Gold RTS) is less than $20 with free shipping that's hardly breaking the bank considering "working on" is no guarantee of support.

I don't get why some of you are all pissy that a flashcart you bought YEARS ago isn't supported. Seriously, suck it up and buy a new one they are dirt cheap. It's not like you're replacing your $200 console. Jeez. It's funny how when OOT3DHaX first came out no one was worried about spending twice that ($40) just for userland homebrew. You guys are becoming too spoiled with your free exploits. Lol

I want to create a list containing flashcards which will never be supported, flashcards which potentially could be supported, and flashcards which are supported.

If you know any flashcards with a ROM (such as the original R4), please PM them to me.

If you know any flashable flashcards, also please send them to me.

I'm under the impression that only DSi flashcards can be flashed? Since they disguise themselves as another game.

 

[urherenow]

from replies on the last couple of pages, It seems many people aren't aware that at least 2 different cards don't even require a DS or hacked 3ds. You can do ntrboot directly on an unmodified 3ds now via .nds file

https://3ds.guide/flashing-ntrboot-(3ds-single-system)

• R4i Gold 3DS RTS : All Versions <= 11.5.0
• Acekard 2i : All Versions <= 4.3.0

 

[N7Kopper]

Now I need a good deal on a flashcard that supports both this and playing games in TWL mode.

I can confirm that the next flashcard DON'T work:
R4 Revolution for DS (NDSL/NDS)
R4 SDHC GOLD Pro (r4isdhc)
R4i v1.4 (r4i-gold.eu)
R4 Chrismas Version (r4isdhc)

Yes, that flashcards can be used for play DS games on 3DS.

 

[MrJason005]

Yes, that flashcards can be used for play DS games on 3DS.

I mean if their firmware is stored on a ROM chip, essentially making it impossible to flash them as ntrboot cartridges.

 

[retrofan_k]

Can we stop with the "when is my shitass flashcart gonna work with this?" before I cut my fucking wrists already? SPEND THE $25 ON A NEW FLASHCART FOR FUCKS SAKE.

I agree. It's only the ones that are tight as a duck's ass who complain about it. Same with the WiiU moaning about paying for a legit VC title for CBHC when it costs next to nothing to buy one.

 

[N7Kopper]

And you can confirm that it can play DSi exclusive games? Because that's my preference. More for making use of hybrid features, but I might want to play a DSi game at some stage.

Today I learned a duck's ass is apparently tight. My Saturday won't be any better.
