Hacking Set up Gateway/HBC on Japanese New 3DS Ver. 8.1.0-0J

[wataznach]

Hey, everyone!

So I just got a Japanese New 3DS from a friend who previously got gateway running on it before. However, he didn't send me any of his SD cards and the setup didn't work when I tried to only use the Nintendo DS Profile exploit with SD card files and red gateway card. Now, the Nintendo DS profile thing shows up instead of freezing/starting gateway or whatever it's supposed to do, so I think I need to restart the exploit process.

What is the cheapest/fastest way to set up Gateway and/or HBC so that I can get games roms running? So far all I've really found is that I may need a game with exploitable game files (OoT3D/CN) or Sky3DS. Is there any easier or cheaper way to exploit yet? Also, would I need a different Japanese Sky3DS or something?

Hi, u cant set up the HBL on 8.1 without cubic ninja, i would recommend u to update to 9.2 with a tutorial to access HBL and set up menuhax (launch gateway through HBL as the 3DS is on and launching your theme) but if u want to take a risk u can do arm9loaderhax (a9lh) that gives u a super early kernel access so u will be able to launch gateway immediately as the 3DS starts even before the NAND (os) starts so u will be able to unbrick your device without a hardmod but if u r new to this scene so dont do it cause its a little bit risky.
i think u should upgrade to 9.2 and set up a CFW cause u wont need gateway anymore and u wont get bans (if u use a flashcart there is a chance u will get banned).
set up menuhax and a cfw and if u want to try a9lh we will help u (i have it and its super awesome)
hope that i helped ya and have a nice day and week

Hey, you're in the same situation as my JN3DS! You won't be able to get out without a copy of JP cubic ninja or ocarina of time. JPN Ocarina of Time relies on either a 3DS with <10.6 firmware or a Cyber Save, which is the JPN equivalent of Powersaves and can get rather pricey.

EDIT: However, you could alternatively get yourself a Nintendo DS flashcart to re-install the Gateway MSET ROP exploit on 8.1J. That is probably your cheapest/easiest option.

If you don't know someone with a <10.6 firmware, your next best choice is to get a Sky3DS, because it costs as much as importing JPN Cubic Ninja and doesn't require the save dongle. From there, you should either do this or update to 10.7 and then proceed with the Plailect guide like everyone else: https://github.com/Plailect/Guide/wiki

Thanks for the reply! If I wanted to play games online until then (with the cartridges) since sky3ds might take long to ship, could I update to 10.7 before getting sky3ds? Also, where can I learn more about the NDS flashcart ROP exploit?

To the first question, yes, except you can do that in Gateway's EmuNand without updating SysNand itself.

Second question, it's pretty much "run a piece of nds software using a flashcart and it will reinstall the proper hack for your DS Profile so it properly boots into Gateway." Said software is a "Gateway Installer" .nds rom and is included in nearly all of the Gateway .zip packs, in a folder called "Blue card"

But if you want to know more about why installing a ROP exploit in MSET (aka System Settings) works, you can read this:

To exploit this vulnerability, you need a working DS Mode flashcart for your 3DS and you must run an NDS Homebrew designed to alter the DS Profile settings strings. When launching the 3DS System Settings application's DS profile settings editor, it will cause the application that edits the DS profile to crash, and this crash pushes custom code into memory from within the edited profile and makes the security co-processor "accidentally" load that code, resulting in homebrew being launched.

Gateway with a private header is not a confirmed cause of bans, cheats with gateway is far superior, when they update the a9lh it would be on top again, the use of 3ds files is awesome, using 9.2 is convenient because of menuhax but sometimes is less stable than mset

Thanks to everyone who has replied! I'm very new to exploits and have only done the spider exploit before with older 3dses, so I'm very inexperienced. I pretty much have no idea how to do what anyone else besides CrispyYoshi is saying.

So should I not update with the default update that will be suggested and instead update Gateway's EmuNand without updating SysNand somehow? How would I do this?

Also, are there any tutorials or threads going into more detail about the NDS flashcart exploit? I'm trying to find some but all seem really complicated and I'm not even sure if I'm looking for the right thing.

I play competitive Mario Kart so I pretty much just need to play online as soon as possible (I have mk7 cartridge) but I don't want to miss out on any potential hacks by updating...

Assuming your SD card already reads as "GATEWAYNAND" on your computer, you probably already have EmuNand set up. Just boot Gateway Mode and perform a system update through system settings. Be warned, though, that exiting System Settings will boot you back into SysNand. Be absolutely sure that you are in EmuNand when you update through System Settings, or you'll accidentally update your sysnand!

Your first step is to get a NDS flashcart that can run on 3DS/DSi, like a DSTWO or R4i Gold (second option being cheaper/consumes less battery. There are fakes so I'm not sure where the best place to buy an R4i Gold is [someone here might recommend one?]). In any case, once you can run .nds roms through your flashcart, just download the Gateway Installer from the Blue Card folder of the GW update pack .zips from Gateway's official website, then run the Gateway Installer, select "New 3DS", and it reboot your system and will fix your DS Profile exploit.

I don't think I've been able to enter EmuNand since getting the 3DS (and the SD doesn't say that either; I had to get a new SD since the original wasn't sent with the 3DS).

What are the risks associated with updating SysNand to 10.7? Isn't there still the option to downgrade it to 9.2?

You cannot downgrade from 10.7 without a copy of Cubic Ninja/Ocarina of Time/Pokemon Super Mystery Dungeon native to your region. You can still set up EmuNand within Gateway Launcher, but you'll need a DS flashcart to get in.

Update to 10.7 and get the game vvvvv. It has a exploit which the. You can use to set up CFW or a9lh CFW

Cubic Ninja rom on sky3ds would still work on 10.7, correct?

I may just update to play mk7 online and invest in sky3ds so that I can do the exploit for multiple 3dses. I mostly just want to make sure whatever I do can be reversed.

Isn't that only a secondary entry, though?

Yes sky3ds can be used on any known firmware so far.

V6 is indeed a secondary exploit and needs setting up on an already hacked 3ds.

So if you want to spend ~$90 go ahead and buy a sky3ds. You can then set up multiple exploits on it and use it all around. You could also look into buying a Ds flashcard as mentioned above. After setting everything up you can still use both the sky3ds and the ds card to play games anyway.

Yes, CN+Sky would work on multiple 3DSes, but you'd need the CN rom for each region. You don't need to buy anything besides a large SD card for any system at or under 10.5 firmware.

VVVVVV is a secondary exploit and requires hacking the save prior to updating. It's digital and cannot be modified through another 3DS, unlike OoT.

EDIT: Ninja'd!

Thanks so much for the help! One last question if anyone here as any experience with it: does sky3ds mk7 rom work well online?

 

[Temarile]

Thanks so much for the help! One last question: does sky3ds mk7 rom work well online?

I highly recommend to avoid going online with a sky3ds. There is this thing called headers. Just Google sky3ds headers and read everything up. I can see if I can find my little essay I wrote on it..

EDIT: not really the post I was looking for but it still helps you.

BEWARE THOUGH: If you want to play online, you'll need a private header.Short explanation: Headers are a piece of code that Nintendo connects to a physical cartridge. It's unique for every cartridge. Nintendo checks this header if you're playing online. It checks if you're the only one with that piece of code online, because ofcourse only ONE physical cartridge is able to play online. Alas, one physical cartridge can't be in two different 3DS' at the same time. Get it? If there are multiple devices with the same piece of code, you'll risk a ban. A private header is a piece of code only you have. You can either buy it (beware of resellers though. They can sell the same thing multiple times) or extract one from a physical cartridge you own using Power Saves.

EDIT 2: this is what I was looking for

You can't play online with the sky3ds. If you don't plan to, you've successfully banned yourself from nintendo servers and you don't actually have to read everything after this. If you do plan on playing online, for instance for trading on the wonder trade in pokemon, or battleing with other players, just continue reading. Well, actually you can but there's something called headers. Headers are basically strings of code that nintendo checks when you're playing online. Every cartridge has its own header. Nintendo checks if your header is on the online servers multiple times, which could mean two things; either you're playing online illegally or you've found a way to insert one same exact cartridge into two devices at the same time. Seeing as the last one is not possible, you must be playing online illegally. Nintendo can ban you from their online servers, thus making you unable to play online again. Those headers can be found on the Internet, they're called public headers. But as everyone can use them, the risk of the same header online multiple times increases, thus increasing your chance of getting banned. So that's why you need something called private headers. It's a header only you and you only own and should never ever share. You can extract the string of code from a retail cartridge you actually own using the power saves save dongle (which you'll have to buy too if you wanna play online with sky3ds). Here's the thing though: there are 3 major manufacturers of games. Their headers are basically: AE, C2 and 45. For example, your copy of game X is from the AE manufacturer (most games are), you do need An AE header. You can't use a C2 or 45 header on a AE game and vice versa. So to be completely covered with playing online, you'd have to have 3 different manufacturers retail cartridges and extract the header from every cartridge. Then you can play online without the risk of being banned.
