    DSiWare Exploit Sudokuhax Released!!!

    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.

    Have you hacked a DS yet.. I have 2 for my boys at home and was considering it but I hear mixed reviews on it. Like the emulators run slow and/or there are many bugs and freeze issues. Any insight?
    [SPOILER= Did I come off like a jerk?? Read more here]Shift_Lock On Forum Issues - Vol. 1

    Disclaimer:
    First I would like to state that this is one persons point of view. It does not reflect this site (wiihacks.com) or any other staff/mod/or admin here. It is solely mine. Now even though a few may have similar points of view this should be taken as one person’s opinion. Also. This DOES NOT reflect all users and noobs here.. Just a select few personality types that pop in time to time. Let’s get started!

    [SPOILER="Outlook On Forum Rules "]Now I realize many of you did not even read the rules and just agreed to them.. Kind of like signing a legal contract without reading the clause that states you just sold your life away… It happens... When it does, YOU are still responsible and held liable for your actions. No matter how much you think its BS... It’s still on you. I for one am among those who did just that when I signed up here... (Shame on me I know) I to did not read them immediately (however I did speed through it to get a general idea)... I was quickly referred to them a few times do to not being thorough enough with “speed reading”...

    [SPOILER="Why we have rules on this site"]The rules here at wiihacks are here for a few key reasons. I’m only going to hit a few.

    Conduct - We know it’s the net, and there are a lot of internet gangsters/bully’s/and plain jack ass’s... We don’t like that here. The ways users conduct themselves reflect the site... We want user to enjoy coming here but respect in general is needed. Flaming and such results in infractions/bans so don’t do it.

    Piracy – This is a big one here, and no one seems to understand... First of all IT IS AGAINST THE RULES OF THE SITE! Which every last one of you members had to agree to follow prior to being a member here. Copyright laws vary from place to place so they are different for others. But we have to follow our copy rights here to protect our site. We DO NOT support piracy and will not assist in it. We don’t want to lose our wonderful site that you as a user come to, to find help. Big brother (the government) and big “N” (Nintendo) may be watching along with a vast amount of other private sectors looking to stop the pirating of copy righted material. Shutting down sites that support it are somewhere at the top of the list to reduce this.

    Personally, I don’t care what you do... I don’t care what your online habits are or how much porn/software/media you download every day. It’s your computer and your life. YOU are responsible for anything that may occur from that. Users who lack a way with words to express themselves in what they are trying to do may get wrongly accused of being a pirate and these things occur: warnings/infractions/bans/threads closed/YouTube videos of dancing pirates/ and many many possible pictures pointing you out.

    We as staff here are obligated to abide by and enforce forum rules. Whether we believe their valid or not. They are in place to protect the site and members of our community. I won’t allow a poor decision result in losing this site.

    Cheating – Play Fair... I support it... Nothing I hate more than losing to a cheater... If I lose I want it to be because the other person was actually better. Cheating takes the fun out of the game... Why make it easier? Do you suck that bad at it? Don’t like the challenge? GET A DIFFERENT GAME! We don’t support cheats here. Users will not be given help on how to become invincible or walk through walls... you want god mode? Unlimited ammo? Go Google it somewhere else. Don’t ask about it here.[/SPOILER]

    There are a lot of users/members that say “this is wiihacks wtf?” or "that’s the point in hacking a Wii”... No it is not….. We assist users in backing up their legally purchased games so they don’t get ruined in the future (we know how kids are)... Before backups I had bought 3 Mario karts! Ridiculous… Anyways, it also allows us to fully enjoy the console and the convenience that some mods add to the system. We make it custom and set it up the way we like it. Kind of like your pc. A lot of users buy the Wii just so they can do that! I will ban anyone who tries to argue that point... Dont be ignorant... [/SPOILER]

    [SPOILER= “So you Think You’re a Hacker”]Warning: Spoiler below is a rant. [SPOILER= "Shift_Lock's Rant about the tough guys"]Really guy? We are “Modder’s” at best... most users aren’t even that. A hacker would shut down this site with a single code line… Not sit here claiming he’s one arguing about rules and why he needed help... I’m not saying we don’t have members that are real “hackers” but face it... You aren’t one of them... Coders and developers are fantastic people that make all this possible. And some of those guys truly are considered hackers at some level. Now, could they hack the pentagon? Probably not, but maybe. Who knows... lol

    The point of this is for those of you that come on here thinkin you’re hot [nice word]... If you were a hacker you wouldn’t need our help and wouldn’t need to hide behind a proxy or redirect to post your nonsense… Get over yourself and just follow our guides. If you can’t “hack” a Wii, what can you do? Can you hit the logout button? Try It! How about facing your fail and going back to the guides to read some more… Leave the “hacking” to the REAL hackers out there. /end rant[/SPOILER][/SPOILER]

    [SPOILER= “Need Help?”] That’s why you’re here right? To get help Modding your Wii. Some users can just navigate the site and never need to post a thing because they can search, read and are on some level tech savvy. Other users need assistance. That’s why we are here... To support and assist those who need the help to mod or to help find solutions to their problems. We like to help… but... We don’t always like to spoon feed arrogant people who demand help or can’t use the search function... If our search is too hard to use there is Google, and if you can’t use Google then you SHOULD NOT mod your Wii...

    We see the same issues every day, same posts, same questions, same answers…. SEARCH FIRST!!! Read a little… Geez people! Too lazy to search for a solution, but can type a wall of text that takes 15 mins to read? C’mon man… step up your game... My spoon hand is getting tired, gonna have to just start [nice word] slapping people with it…

    Don’t be lazy... Help us, help you... If you’re really stuck then we take no issue helping as long as it’s within the lines of the rules... The “grey” area is kind of tough... The staff is here on OUR own time and do not get ANYTHING for being here helping you... We are not paid and don’t see any part of the donations... The donations go strictly to site development. Can you fathom how much it costs to run a site of this level and host the files that we do? Everything costs money... Just not the staff here so remember that the next time you are impatient or lazy... We aren’t getting paid... We are helping because we want to... So keep your cool and dont lose your head... Don’t give us reasons to NOT help you. If you do, well... Then we won’t...[/SPOILER]

    [SPOILER= "Mutli Threads, Double Posts and bumping"]Ok.. So It might not bother you but it bugs the crap outta me! It clutters the forum and makes you come off as impatient and ungrateful.

    Mutli threads - Do you really need more then one?? Mods and staff see EVERY POST MADE! You only need one thread for your issue.. Dont create more then that..

    Double posts - You have an "EDIT" button... it will be right under your post to the right.. it will say "EDIT".. say it with me now.. "Eh-d-it" ...... Use IT!!!

    Bumping - If no one has got to you yet there IS a slim chance it was missed.. probably not.. As we answer what we know. so if we dont know, We will leave it for someone else or atleast contact another Staff member for assistance. So WAIT and be PATIENT!You can bumpAFTER 24hrs! and that it!!! I will infract/ban/scold/kick your dog/delete any users who abuse this after warnings....[/SPOILER]
    More to come (without a doubt) so stay tuned for the next edition! Peace I’m out![/SPOILER]

    So this is basically a softmod for DSi? No flashcart from Hong Kong needed now? Does this apply to the DSi XL?
