Tutorial  Updated

Installing Sudokuhax on 3DS 4.x-9.2

So yeah... Title says it all. Ever heard of the DSi exploit named Sudokuhax? You want it? Okay! Here's some info:

  • DSiWare does NOT have access to game card, slot 1.
  • DSi Homebrew Channel ONLY supports a maximum SD card size of 2GBs, because of libnds? (If anyone want's to fix that problem, go ahead).
  • Does not support DLDI patching (sucks, right? Can't even run moonshell or a lot of legacy homebrew with that -_-)
  • You need a NDS mode flash card, so ROP Multiloader can be installed. (New method, doesn't have this requirement :D)
  • DSiWare already installed on the console (it must be at least 4MB's in size!) UNLESS you use the NEW method.
  • Ninjhax or Spiderhax (browser, O3DS) is currently required for the NEW method. The old method, requires a NDS flashcard or other method of installing the ROP chain for MSET.
NOTE - QUOTES ON FREEZING:

It works on my 32gb fat32 32k cluster. I used the modified boot.nds from zoogie link.

Yes cluster size is the issue with hbMenu. If it's anything beyond 8192K on 16+ GB size SD cards (not sure if this counts for anything smaller) then hbMenu won't start anything. You just get that white screen. But the problem was I had screen buffer bugs with GBA games when I had my 32GB SD card formatted to 8192k cluster size.

The ROM

1.) Google "DSiWare SDATs" - click on the link with the domain "hcs64".
2.) Scroll down to the bottom and select "page 3" - you'll see a post by "CaitSith2", posted on "March 27, 2015".
3.) Click on "nomodcrypt" and download the archive.

I can't post a direct link to the files, as it isn't allowed here. Sorry.

PC Utility

1.) Search that ISO site for "Play DSiWare in your 3DS!".
2.) Click on the link and go to page 6, post 59.
3.) Download "DSiWare_Injector.zip".

Good! That's the PC utilities downloaded.

Edit: For those of you who can't find the post, I uploaded the injector to my dropbox. Here it is: https://dl.dropbox.com/s/8pjwmgyiwg5bil4/DSiWare_Injector.zip

DSi Homebrew Channel (Mileage may vary)

1.) Download this: http://filetrip.net/nds-downloads/applications/download-dsi-homebrew-channel-1-0-f25356.html

OR Download this modified version, by @zoogie : http://gbatemp.net/attachments/boot-zip.18916/

OR the latest release (also credits to Zoogie): http://gbatemp.net/attachments/boot-zip.21417/

You don't need a 2gb card. just use nds_hb_menu.
Freshly compiled build attached for your homebrewing pleasure. :P

That's pretty much all you need :P Okay, now for the messing about.

***New Method: 4.x-9.2*** (Concept by Zoogie)

1.) Download a copy of Decrypt9, from either of the two links:
OR try @zoogie 's tool:

Here's a version of TWL_PADGEN that includes a browser-launchable decrypt9 -- no cubic ninja needed.
Use gateway firmware for nand dumping and reinjection and such.
Press select to create xorpad.

http://gbatemp.net/attachments/twln_padgen_spider_launcher-zip.21674/

2.) Place the file in their respective places (Launcher.dat, goes at the root of the 3DS SD card. "Decrypt9", goes in the "3ds" directory, if you're using Ninjhax).
3.) Launch the payload.
4.) Select "Decrypt Nand Partitions" then press "x", to backup.
5.) Once finished, shutdown the console.
6.) Rename "SUDOKU-Electronic_Arts_Inc..nds" to "00000002.app".
7.) Rename "dsiware.sav" to "public.sav" (this file is located in "DSiWare_Injector".
8.) Remove the 3DS's SD card and insert it into your computer. Navigate to SD:/Decrypt9 and open "TWLN.bin" with a piece of software such as WinImage.
9.) In WinImage, go to "\title\00030005\42383841\content" and inject the "new" 00000002.app. You can inject the new file by clicking on "Image" then "Inject".
10.) Go to "\title\00030005\42383841" and create the directory "data" (Image -> Create Folder).
11.) Open the "data" directory and inject the "public.sav" file.
12.) Go to File -> Save.
13.) Remove all files from "SD:/Decrypt9", EXCEPT FOR TWLN.bin!
14.) Eject the SD card and put it back into the 3DS.
15.) Re-launch D9, then click "Decypt Nand Partitions" then press the restore button (y).
16.) Accept the confirmation (if any) and wait for it to finish.
17.) Reboot the console, then go to System Settings -> Internet -> Nintendo DS Connections.
18.) Sudoku should load. Press start and Sudokuhax should load. It'll show an error about boot.nds
19.) Power down the console, eject the SD card and put it into your computer.
20.) Transfer the DSiHomebrew channel (boot.nds), to the root of your SD card.
21.) Reinsert the SD card into the console and relaunch Sudokuhax.


***BELOW INSTRUCTIONS ARE 4.x ONLY!***

3DS Injection Tools

1.) Download ROP Multiloader here: http://filetrip.net/3ds-downloads/homebrew/download-ropmultiloader-1-1-f32981.html

Getting your DSiWare Title ID's

1.) Go to system settings ---> Data Management ---> DSiWare.
2.) Copy the DSiWare that you want to be "Sudokuhaxed" to the SD card (make sure no other DSiWare is on your SD! It'll make things easier).
3.) Shutdown the 3DS.
4.) Remove the SD card and insert it into your computer.
5.) Go to "SD:\Nintendo 3DS\<ID1>\<ID2>\Nintendo DSiWare" - you'll see a title with a name similar to this: 4B344856 (This is just an example).
6.) Make sure it's at least 4MB's in size.
7.) Note down the name of the file (don't bother about the file extension - you don't need this).
That's the ID's sorted! Great! :vul2:

Sorting out the stuff

1.) Extract "SUDOKU-Electronic_Arts_Inc..nds" from "decrypted_titles_nomodcrypt.7z" (requires 7Zip or any other archive handler that supports the .7z file extension).
2.) Extract "DSiWare_Injector.zip".
3.) Copy/Move "SUDOKU-Electronic_Arts_Inc..nds" into the "DSiWare_Injector" directory so that it is with it's pals "dsiware_InjectTitleIDinMset.py" and "MsetForBoss.dat".
4.) Rename "SUDOKU-Electronic_Arts_Inc..nds" to "dsiware.nds".
5.) Open "dsiware_InjectTitleIDinMset.py" with a text editor, so that the title ID can be changed.
6.) Change this:
title_ID="xxxxxxxx" # 8 characters or die.

to this:

title_ID="<THE TITLE ID THAT YOU SHOULD'VE NOTED DOWN EARLIER!" # 8 characters or die.

7.) Save the changes and run "dsiware_InjectTitleIDinMset.py" (You must have Python installed!).
8.) Copy "dsiware.nds", "dsiware.sav" and "MsetForBoss.dat" to the root of your 3DS's SD card, (NOT THE NDS FLASH CARD!).
9.) Extract the DSiHomebrew channel and copy "boot.nds" to the root of your 3DS's SD card, just like the previous step.
10.) Extract "235679-ropMultiloader 1.1.zip" and copy "rop_multiloader.nds" to your flashcards SD card (NOT 3DS's!)

You're almost done!

11.) Eject all SD cards and put them back where they belong (don't ask stupid questions. You know where to put it, hehe.)

Installation onto the console


1.) Launch ROP multiloader from your flashcard and install the MsetForBoss exploit.
2.) Go to system settings ---> Profile ---> Nintendo DS profile - you'll see a magical menu, hehe.
3.) Select the option to inject the DSiWare. Wait for it to finish and shutdown the console.
4.) Turn the console back on and launch the DSiWare that you had injected Sudoku into.
5.) The exploit will load after the start menu.

You're done! I've only found this useful for installing the profile exploit, on the go without the need of carrying a flashcard with me. This lets you play NDS games and you could just re-install the exploit with Sudokuhax. Just copy any ROP installer to your 3DS's SD card and rename it to boot.nds.

Would be great if Moonshell2 could be ported to work with this :) Or even better - have a DLDI patch that lets you use more homebrew (nothing is impossible), though I doubt someone would be willing enough to make this happen -_-.

Any errors in this tutorial? Let me know and I'll correct them.

DISCLAIMER: If you break your console, I am not responsible for that. You do these sort of stupid things at your OWN risk. ALWAYS HAVE A BACKUP! Don't come crying to this forum if you've bricked your 3DS and don't have a backup of your NAND - it's just plain sense to have backed up your console, you're an idiot if you don't have one.

Special thanks to a certain user on this forum, for helping me out with the details. He prefers not to be mentioned as he'd rather not receive nooby PM's.

Can we get a list of what works and doesn't. I tested some stuff I had on an old r4i gold ds card laying around not being used and this is the results:

Working: Nesds and gameyob and dscraft.nds
Not working: nitrografx, neods, jenesisds

Was hoping neods worked but oh well from what I understand, it needs to be udated to work with this sudokuhax method. Anyone else want to contribute on what is working.

For those having trouble with the boot.nds file, just rename the ROP loader you want to use to boot.nds and put it on the root of the SD card. If you're using CakesROP, make sure to put the ropCustom.txt on the root as well. This works for me on my 2DS with a 64GB SDXC card. The HBMenu really doesn't like SDXC cards, regardless of cluster size, ha ha

Hmm I tried that and got a frozen white screen with this horrible high pitch sound. Reverted back to using the modified boot.nds as it works well.

But does anyone know if I did decide to update if the hax will continue to work on 9.9? I not planning on doing it but wonder if it sticks. Maybe someone with a hardmod can test?

This hack will work on 9.9, yes, but no other hacks are present on 9.9, so it would just be a strictly DSi homebrew exploit, with no 3DS access. And, of course, there's no way to install this hack to a console currently running over 9.2FW, so it's not as though this will be a popular thing to do.

Is it possible to use rxTools 2.6's decryption tools instead of running D9? I'm okay with having to use D9 if rxTools can't, but I'm just curious as to whether or not I can do it with what I already have.

Also, is the "\title\00030005\42383841\content" path the same for consoles of all regions? My sis-in-law's 3DS is a JPN console that loads a USA emunand. If I can get this running on her console, that would be awesome. I already plan on putting this on both of my 3DSes to reduce the need of keeping a DS flashcard handy when I need to rerun the ROP installer to switch between GW/rxTools.

rxtool's crypto stuff is based on decrypt9 anyway.

But rxTools doesn't dump decrypted twl like the latest d9
So I guess I'll just use D9 instead, which isn't a big deal. What about the region-related question I had? Is the title path the same for all regions? I'm assuming that they are because I don't see any other listed paths in the OP, but you know the old adage about making assumptions...

It is the same.
