3DS:Alternate Exploits/Homebrew Launcher (PicHaxx)

Required Reading

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" (free on eShop) installed on your device
  • You can scan this QR code using the Nintendo 3DS Camera for a direct link to the eShop app
  • 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)
• The latest release of unSAFE_MODE

Instructions

Section I - Prep Work

1. Power off your device
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 region/version from the unSAFE_MODE .zip's otherapps_with_CfgS folder to the root of your SD card and rename it to otherapp.bin

   • 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
