Tiramisu – Nintendo Wii U

Tiramisu is a new Wii U exploit similar to Haxchi and CBHC. This exploit works on the latest firmware, 5.5.5. Modding your Wii U allows you to use emulators, dump Wii U games to USB or internal HDD, play out of region games, backup, edit and restore save files, download and install Wii U games etc. If you have an existing legacy CFW on your Wii U, you’ll need to uninstall it first.

What you’ll need
  • SD card (32GB+ recommended)
  • A Wii U with internet access.
  • A computer to place files onto SD Card
SD Preparation
  1. Download the latest files, and download the sigpatches
    • Select Nanddumper, PayloadLoader Installer and Base-Tiramisu
  2. Format SD Card to FAT32 using GUIFormat
    • Format SD Card with 32K (32768) allocation unit size
    • Do not name the SD card “wiiu”, as it will cause issues with homebrew
  3. Extract the contents of files.zip onto the formatted SD Card, then copy 01_sigpatches.rpx into /wiiu/environments/tiramisu/modules/setup on the SD Card
Launching Browser Exploit
  1. Plug the SD card into your Wii U, then navigate to wiiuexploit.xyz in the Wii U Internet browser app
