DSiWare Exploit Sudokuhax Release

January 27th, 2011 by yellows8 · 88 Comments

Update: 28/01/2011 Nintendo removed Sudoku from the EUR/AU and USA DSi Shop. At the time of the USA Sudoku removal, there was 234 injection requests from the client software, and 1684 client software release archive downloads. The download/request ratio is large because there was several downloads per minute, while each user took several minutes to buy Sudoku and inject Sudokuhax, thus there was one injection request every couple minutes. Current download and injection stats are available here.

Update: 02/02/2011 USA Sudoku was removed from NUS, EUR Sudoku is still available on NUS but both aren’t available from any of the DSi Shop regions. None of the Sudoku regions were updated on NUS yet. And at this time when trying access the Sudoku page from DSi Shop “Account activity”, it displays an error saying this software was removed due to certain circumstances.

Update: 03/24/2011 USA Sudoku was updated and is now available on DSi shop again. EUR/AU Sudoku was not yet updated. On roughly 03/30/11, EUR/AU Sudoku was updated and is now available on DSi Shop. This update fixes all the Sudoku string bugs, and the game will check for Sudokuhax and delete it when detected. Sudokuhax is dead for this updated Sudoku version.

As you may remember we started looking at the DSi about two years ago. Despite some early attempts using savegame hacks for hybrid card games we eventually resorted to more complex attacks that involved soldering many wires to tiny points on the PCB to be able to trace and modify the RAM. However, doing this is not feasible for the average homebrew user so we used the knowledge we gained through these complicated attacks to get more information about the whole system which allowed us to experiment with DSiWare games in the end. We also learned how to create savegames so we can now do what we did three years ago with the Wii: Savegame hacks!

In early December we managed to get DSi mode code execution by exploiting the DSiWare application ‘Sudoku’ by EA. Sudoku is only available for regions USA and EUR/AU. Exploiting DSiWare is interesting because in DSi mode the DSi SD card slot is accessible, the whole 16MB RAM is available, and the CPU is clocked 2x higher than DS-mode. The max size of the embedded code that can be loaded directly via this exploit is limited so a small payload was needed to chain load to another application. Initially a wifi loader was used, but this was switched to load from the DSi SD card slot. The SD card loader boots /boot.nds from the SD card directly from Sudokuhax.

DSiWare exploits can’t access gamecard slot1, it’s likely that only launcher/sysmenu can access slot1. The main advantage of DSiWare exploits over hybrid card EEPROM savedata exploits is SD card access, *and* the exploit supports SDHC. :)

Usage of the exploit is described below:

  1. Export Sudoku to SD card via the data management menu.
  2. Sudokuhax will then be injected into the Sudoku application via client software. The client software uploads DSi-specific data from the Sudoku application to a web server, then injects the retrieved data into the Sudoku application.
  3. Copy the output binary to SD card with the same filename as the original.
  4. Copy Sudokuhax from SD card to “internal memory” via the data management menu.
  5. Launch Sudoku, then press button A or touch screen at the Sudoku title screen.
  6. Now boot.nds on SD card will be run.

The data uploaded by the client software includes the anonymous DSi-unique console ID, and other data required for modifying the Sudoku binary on SD card. This data is used for logging unique web server requests.

The client software is available here. The tracker for the client software and Sudokuhax is available here. Client software source code licensed under GNU GPLv2 is available here.

    Guys, that’s just awesome!
    I can already see frustrated faces of the guys who ordered the iEvo, lol :D
    Btw, if 3DS supports DSiWare, shouldn’t this exploit work on 3DS too?

  • 3 SifJar // Jan 27, 2011 at 11:50 am

    Fantastic work. I’m guessing the DSiWare game will just get pulled soon though, and replaced once the exploit is fixed :(

    Quick question: Does file system access work in homebrew? (e.g. can homebrew like loaders which need to access other files work?)

  • 4 oldtopman // Jan 27, 2011 at 11:51 am

    Thank you!
    This is just the thing I have been waiting for and hopefully I can get it this evening before it is pulled.

    SifJar: We’re working on a libnds patch for DSi sdmmc. SD card can’t be used with old homebrew via DLDI since the MMC bus is arm7 only, homebrew will need rebuilt with latest libnds once support is added.

    popoffka: Only if Nintendo doesn’t block it by then, and only on USA/EUR 3DS since Sudoku is USA/EUR only. But it’s likely(a guess) 3DS has a DSi-mode, where 3DS-only hw is disabled.

  • 7 RupeeClock // Jan 27, 2011 at 12:41 pm

    Fantastic work guys, this exploit was really easy to do, and now I’ve managed to test some homebrew.

    First I tried WordUp.nds, it’s a puzzle game.
    Didn’t work, it was stuck on the enable/disable highscore screen.
    Then I tried a version of NESDS with an injected NES rom, it just failed to boot.
    Next I tried Phidias, a painting homebrew. That would get to the canvas size option, but couldn’t get past it.
    Then I tried Pocket Physics, I was able to get into the main game in that, but then that’s when I realised, the touch screen wasn’t working!

    Weird huh? This exploit and the touch screen just don’t seem to agree! Button inputs work just fine though.

  • 8 yellows8 // Jan 27, 2011 at 12:51 pm

    Current homebrew using FAT will not work, those will need recompiled with a future libnds. Touchscreen and audio will not work with old homebrew, those work fine with recent libnds.

  • 9 RupeeClock // Jan 27, 2011 at 1:00 pm

    Yes, I’m aware that FAT wouldn’t work, which is why I tried to use homebrew where FAT access could be avoided, although the touchscreen issue got in the way first.

    So recent libnds huh? I’ll have to try downloading something newer.

  • 10 RupeeClock // Jan 27, 2011 at 1:12 pm

    Well I did find a homebrew that works nicely from the SD slot, a little 3D tech demo called Multiview.

    TB: Support for DSi SD card was committed,(doesn’t work for SDHC AFAIK) you can track DSi changes by the DevKitPro svn logs and the libnds tracker patches.

    We’re working on another exploit. We tried to find vulns in the free DSiWare for ages but never found anything.

    Little question though : in DSi mode, is the VRAM bigger on not ?

  • 33 yellows8 // Jan 28, 2011 at 3:35 pm

    electrical: You’d need to recompile open-source homebrew with latest libnds.

  • 34 Eon-Rider // Jan 28, 2011 at 3:53 pm

    The game was pulled from the Australian shop at around the same time as the European shop. I guess you guys don’t care since the two seem to be identical to each other but I think it’s worth updating the first sentence for completeness’ sake and to not get any Australian’s hopes up. :P

  • 35 yellows8 // Jan 28, 2011 at 6:46 pm

    windwakr: Yes, all crypto is done server-side.

    eviltroopa: VRAM is identical to DS.

  • 36 oldtopman // Jan 28, 2011 at 7:38 pm

    How portable is this exploit (to other games)?
    Also: Shouldn’t you be able to release a redistributable installer now? This will be legal because the Sudoku game won’t work, it will have been recompiled/edited/whatever to load your code.
    For you to get the keys, all you have to do is find the encryption key based off of the DSi Browser and then you can re-encrypt your exploited sudoku.
    I could just be speaking out of my ignorance though…

  • 37 winmaster // Jan 28, 2011 at 8:25 pm

    Wonderful, I’ve been waiting since launch day for something like this! Too bad Sudoku was removed by the time I read this.

    Just a suggestion though: If you make a new game exploit, don’t release it until after the 3DS, that way we may be able to have some homebrew on there too.

    Also, I just noticed that the crashable list of DSiWare you removed from DSiBrew is still in the archives.

    Finally, I have a question. If I read that post correctly, Slot-1 access is currently not possible. Will this be possible in the future?

    Great job guys. Reading this made my day.

  • 38 yellows8 // Jan 28, 2011 at 9:04 pm

    oldtopman: If you’re asking something like “can you make a injection app, which generates the the content key and encrypts the copyrighted .nds and sudokuhax”, then no. Tad(DSiWare exports) content crypto uses AES engine F(X^Y) where F is an unknown function implemented in AES engine, thus it can’t be de/encrypted on PCs.(linux/win32 etc) Also, we can’t do something like that without leaking a DSiWare .nds(however arm7i/arm9i bins would be still encrypted, decrypted bins are required for booting it) and it’s illegal to redistribute copyrighted software like that.

    winmaster: See comment #6, 3DS DSiWare probably would have 3DS-hw disabled. Thus there’s not much point in 3DS DSiWareHax for using 3DS-hw directly from the exploit. Slot1 access via DSiWareHax is impossible. Hw that is disabled can never be enabled again without a hard-reset.(power button etc)

    ron975: I already answered that in comment #29.

  • 43 Techokami // Jan 29, 2011 at 2:06 pm

    Well, with how fast Nintendo pulled the affected game from its market, DSiWare-based exploits are going to be a hell of a lot harder. But hey, at least EA sold 200 more copies of this game in the span of a few hours, and Nintendo made a small commission from each one!

  • 44 ron975 // Jan 29, 2011 at 2:51 pm


    So I assume it’s a DSiWare exploit?

  • 45 yellows8 // Jan 29, 2011 at 2:57 pm

    ron975, yes more DSiWareHax.

  • 46 winmaster // Jan 29, 2011 at 3:33 pm

    @yellows8 Thanks for answering my previous questions.

    Could a Homebrew Channel be made for the DSi? If so, is it possible to launch it without disabling Slot-1? (Maybe a system menu patch?)

    Also, I just thought DSiWareHax could be useful on the 3DS because some homebrew is better than no homebrew.

  • 47 yellows8 // Jan 29, 2011 at 4:15 pm

    winmaster: We currently are not aware of any title launching vulns that could allow a DSi HBC. And you can’t modify launcher/sysmenu or any title since the RSA signatures are verified on launching, the .nds itself is signed. I’m assuming that launcher disables slot1 automatically during title launching, regardless of bits in the header.
    Any specific reason why you want slot1 access?

  • 48 winmaster // Jan 29, 2011 at 6:06 pm

    I was hoping to be able to dump/restore savedata to game cards.

  • 49 Nathan // Jan 30, 2011 at 2:20 am

    What do you guys want to ultimately achieve with this?

  • 50 spinal_cord // Jan 30, 2011 at 6:49 am

    This might sound like a stupid question, but would it be possible for a DSi homebrew to switch to DS mode and allow loading older non-DSi homebrew? a lot of homebrew is now either abandoned (and closed source) or wont easily (or at all) compile with recent dkp builds.

  • 51 Zachary // Jan 30, 2011 at 8:06 am

    That’s pretty awesome, can’t wait until somebody makes it more accessible to noobs… like me.

  • 52 winmaster // Jan 30, 2011 at 9:36 am

    Thought: DSDownloadPlay must have slot1 access because Pokemon Black and White can use it to access your savedata on a Diamond/Pearl/Platinum card, so shouldn’t there theoretically be some way to launch a title without disabling slot1?

    BTW, everyone says that exploiting DSDownloadPlay is impossible, but I don’t think I’ve ever seen a reason why except for the fact that it would be DS mode, which is undesirable.

  • 53 yellows8 // Jan 30, 2011 at 11:16 am

    winmaster: Yes that does have slot1 access but it’s ds-mode so exploiting it is rather pointless. There’s no reason why dlplay second-stage wmb loaders couldn’t be exploited. I actually have an exploit for a WMB bin but releasing it doesn’t have much point for DSi-mode since WMB is DS-mode. I can’t legally release it if I wanted to: would need to redistribute the copyrighted JP DS Station WMB bin, and people would need to either setup a softAP or change their router SSID/WEP key.

    Zachary: What exactly do you mean? We’re working on more exploits, we can’t do much about Nintendo removing the targets so fast besides more hax.(Would be nice to exploit a popular DSiWare, presuming that Nintendo would care enough about profits to not remove it.)

    Nathan: Currently since we’re not aware of any vulns that could allow a DSi HBC, so just load full DSi-mode homebrew from SD card, which Sudokuhax already does.

  • 54 yellows8 // Jan 30, 2011 at 11:27 am

    spinal_cord: Only launcher/sysmenu can activate DS-mode, DSiWare exploits can’t access the registers for that since the titles’ arm7 crt0 disables access to those registers. Even if that was possible, the loaded homebrew couldn’t access SD card in ds-mode and would have to use flash card for FAT.

  • 55 SifJar // Jan 30, 2011 at 3:23 pm

    spinal_cord & yellows8: In addition to what yellows8 said, even if it were possible to switch to DS mode, surely a flash card couldn’t be used for FAT because slot-1 can’t be accessed once DSiWare has been launched? Or would that be negated by theoretical DS mode activation?

  • 56 yellows8 // Jan 30, 2011 at 3:31 pm

    SifJar: I’m assuming that slot1 hw disable is only for DSi-mode, after switching to DS-mode I’d assume that slot1 could be accessed regardless if slot1-access was disabled before activating DS-mode.

  • 59 igeek5 // Feb 1, 2011 at 6:54 pm

    just a question. i’m kinda new to all this, but is it possible to exploit other games in a similar manner? such as the web browser, or flipnote studio? what makes sudoku so special?

  • 60 yellows8 // Feb 2, 2011 at 12:17 am

    igeek5: Yeah we’re looking for more exploitable games. Sudoku had a savedata ASCII string buffer overflow. Flipnote uses UCS-2(UCS-2 isn’t exploitable) we haven’t found anything in flipnote and opera there’s nothing useful in savedata either. Basically we managed to exploit Sudoku not free titles because Sudoku used sprintf and strcpy, the free titles use UCS-2 for strings if anything.

    Great work TT!

  • 63 Pachi-chan // Feb 9, 2011 at 3:50 pm

    I was browsing the DSi Shop today and I noticed several other EA titles on there.

    Considering that EA has already produced a title that was exploitable, why don’t we take a look at some of their other titles on the DSi Shop and see. I think I recall a Texas Hold ‘Em software there too or something like that. Not to mention there is other software in the 200 points section that is shovelware basically, and would likely be easy to exploit. I hope someone takes a look into that. XD

  • 64 yellows8 // Feb 9, 2011 at 8:15 pm

  • 65 Pachi-chan // Feb 10, 2011 at 1:01 am

    You didn’t catch my intent proper, if I were skilled enough to test these vulns myself I would. :/

    However I don’t have skill to test them, and I likely wouldn’t know a vulnerability even if it slapped me in the face and raped me unless there were an already compiled program to plug the data into that plugs code in wherever it can and returns a visible “You found an exploit!” message. >_<

  • 66 Pachi-chan // Feb 10, 2011 at 1:03 am

    That’s why I made some suggestions, because aside from blindly editing that wiki page and adding titles I think should be tested, I’m only a smart end-user of this stuff. xD

  • 71 Tux // Apr 30, 2011 at 12:53 pm

    Would it be possible to hack other WiiWare, like the ones included in Dsi XL ? Or even the photo channel (since pictures are in .bin format) ?

  • 72 yellows8 // Apr 30, 2011 at 9:14 pm

    DsProjekts: Exported DSiWare from data management are locked to the console it was exported from, attempting to copy someone else’s old Sudoku tad to your DSi will not work.(Tad header MAC address and tmd/srl console-unique keys would be different)

    Tux: Did you mean DSiWare? Other DSiWare can be exploited of course.(But I doubt the DSiWare which comes with XL is exploitable, not much in the saves for those) DSi photo app uses .jpg not .bin.(And no-one managed to crash the photo app either)

  • 73 DsProjekts // May 1, 2011 at 5:14 am

    yes i know, but i need it.

  • 74 DsProjekts // May 1, 2011 at 5:15 am

    and probably it work on the 3Ds?

  • 75 yellows8 // May 1, 2011 at 11:08 pm

    DsProjekts: The only way to get you a vulnerable Sudoku tad would be to re-encrypt the console-unique encrypted sections, but we can’t do that with a web server. And we won’t do that manually either, just wait for other dsiwarehax.

    Yes other dsiwarehax should work on 3DS though in dsi-mode.(With eshop in late May) Transferring hax via the DSi->3DS system transfer should work, but if they changed the dsiware SD card export format/keys 3DS uses, hax couldn’t be injected that way for a long while.

    Patxinco: Guess I have to RE settings more, afaict they didn’t change DSiWare sdcard import code much, but they did change a bunch of banner code.(not sure what for)

    Tux: I use arm-eabi-objdump.(I can’t afford IDA Pro, but I heard they aren’t really allowing individuals to get an IDA Pro license anymore either…)

    DsProjekts: You can’t redirect shop comms to download the old Sudoku, the tmd and ticket are downloaded via HTTPS. The cetk is not available on NUS.

    @yellows8 I see on dsibrew that all future DSiWare HAXX will not work due to the System Menu’s refusal to import the save file. Is this true, and if so, how did Nintendo manage to do this?

    winmaster: It’s true, all DSiWareHax is dead with 1.4.2, details later.

    EDIT: Btw, it’s system settings(Data Management) which does DSiWare import from SD card, not launcher/sysmenu.

    @yellows8 Thanks for the info. I thought the settings were a part of system menu.

    so, i updated my dsi to 1.4.4, so does this mean that there’s no hope for me to get homebrew on my dsi.
    and also, is there any possible way to get my dsi’s firmware back to 1.4.1?

  • 85 yellows8 // May 28, 2012 at 6:51 am

    Yeah once you update to 1.4.4 *all* means of DSi-mode code exec are dead unless you already had DSiWareHax prior to 1.4.2. With 1.4.2+ the only way to get DSiWareHax, is to solder your DSi to dump NAND, and extract dev.kp from it.

    You can’t even use DSiWareHax anymore in the first place when you don’t have the required DSiWare.
