Technical Details (optional)

PicHaxx is an exploit for the game Pokémon Picross released by zoogie, originally discovered and demonstrated by MrNbaYoh.

This method of using Seedminer for further exploitation uses your movable.sed file to write a custom save file for Pokémon Picross, which can then be used to launch the Homebrew Launcher.

This process will overwrite your Pokémon Picross save file, if you have one. If you wish to preserve your Pokémon Picross game data, you should make a backup of your 00000001.sav file before overwriting it.

What You Need

  • The game “Pokémon Picross” installed on your device
    • If you have downloaded it before, you can redownload it
    • Your SD card must be inserted in your device to install Pokémon Picross
  • Your movable.sed file from completing Seedminer
  • The latest release of Luma3DS (the Luma3DS .zip file)
  • otherapps.zip (direct download)

  2. Insert your SD card into your computer
  3. Copy boot.firm and boot.3dsx from the Luma3DS .zip to the root of your SD card
    • The root of the SD card refers to the initial directory on your SD card where you can see the Nintendo 3DS folder, but are not inside of it
  4. Copy the otherapp payload for your model/region/version from otherapps.zip to the root of your SD card, then rename the payload to otherapp.bin
    • Do not add the .bin extension if you do not already see it
  5. Copy movable.sed from your computer to the root of your SD card

Section II - PicHaxx

In this section, you will create a hacked Pokémon Picross save file that, when loaded, will run the Homebrew Launcher on your device.

  1. Open the PicHaxx Injector website on your computer
  2. Select your movable.sed file
  3. Select “Build and Download”
  4. Wait for the process to complete
  5. Navigate to Nintendo 3DS -> <ID0> -> <ID1> -> title -> 00040000 -> 0017c100 -> data on your SD card
    • The <ID0> will be the same one that you used in Seedminer
    • The <ID1> is a 32 character long folder inside of the <ID0>
  6. Copy the newly downloaded 00000001.sav file to the data folder on your SD card
    • Overwrite the old save file when prompted

  7. Reinsert your SD card into your device

  9. Launch “Pokémon Picross”
  10. If the exploit was successful, your device will have booted into the Homebrew Launcher

  2. Once you see the HOME Menu, press the (Left Shoulder) and (Right Shoulder) buttons at the same time
    • The camera applet should appear
  3. Power off your device
