Launching the Exploit

Join the DS⁽ⁱ⁾ Mode Hacking! Discord server for guide development and help.

We'll start by first setting up your SD card to launch our exploit. For most users, we recommend using an exploit called "Memory Pit" which takes advantage of a flaw in how the Nintendo DSi Camera application handles image metadata.

Launching the exploit will boot you into TWiLight Menu++, a homebrew application that acts as a replacement to the DSi Menu.


If you don't plan on installing Unlaunch and have either the DSi Browser or Flipnote Studio, it is recommended to use either stylehax or Flipnote Lenny instead. Which is the best exploit?

Section I - Checking your DSi Camera Version

  1. Power on your console
  2. Open Nintendo DSi Camera
    • If you are prompted to complete the camera tutorial, do so now
    • If the tutorial crashes as you try to complete it, your Nintendo DSi camera hardware is likely broken in some way and you will not be able to use Memory Pit. Please use an alternate exploit
  3. Open the album using the large button on the right
  4. Take note of whether you have a Facebook icon alongside the star, clubs, and heart, outlined in red here: Screenshot of where the Facebook icon is located

Section II - Memory Pit

  1. Download the correct Memory Pit binary for your Nintendo DSi Camera version:
  2. Navigate to sd:/private/ds/app/484E494A/ on your SD card
    • sd: is the root of the SD card
    • You will already have these directories if you have previously taken photos to your SD card via the Nintendo DSi Camera application
    • If they (or just 484E494A) do not exist, please launch the DSi Camera application for the folder(s) to be created
  3. Inside the 484E494A folder, rename the existing pit.bin file to tip.bin
  4. Place the Memory Pit pit.bin file in the 484E494A folder
  5. If there's a folder named DCIM in the root of your SD card, make a back up of it so you don't lose the pictures inside, and then remove it from the SD card

Section III - Launching the exploit

  1. Ensure your SD card is inserted into your Nintendo DSi
  2. Boot your Nintendo DSi and launch the Nintendo DSi Camera application
  3. Select the SD Card icon in the top-right
    • If you receive a message saying your SD card isn't inserted, please use another SD card
    • If you receive a message saying that your SD card cannot be used, ensure your SD card is formatted correctly
  4. Open the album using the large button on the right
    • The screen should flash magenta if Memory Pit was copied correctly


If the top screen turns green, you do not have TWiLight Menu++'s BOOT.NDS on the root of your SD card. Follow the prep work again.


If you enter the SD card camera album and nothing unusual happens, ensure that you downloaded the correct version of Memory Pit for your version and region, and placed it into the correct folder on your SD card. Also ensure that the DCIM folder does not exist on your SD card.


Taking photos with the Memory Pit exploit on your SD card will cause the exploit to stop working properly and you will have to copy it over again.

You can now use TWiLight Menu++! First, it will ask you to select your language and region. These do not need to match your console's language or region so set them to whichever you prefer. Next it's recommended to continue on and make a NAND backup. This can potentially be used to save your console if anything bad happens in the future.
