This homebrew application makes permanent changes to the Wii's NAND, thus, this application should be used with caution.

Please read the entire Readme before running the Priiloader installer.

Priiloader is a modded version of Preloader. Just like Preloader, Priiloader places itself in boot sequence before the system menu. By this Priiloader has the ability to:

  • Patch memory just like StartPatch or Preloader. hacks_hash.ini should be on the sd in sd:/apps/priiloader (only once, they get copied to NAND) and can be found here.
  • Save the user's Wii from banner & other kind of bricks that aren't ios/boot2/nand corruption related
  • Start something else than System Menu on power up (a dol file, BootMii, Homebrew Channel)

This tool modifies the normal behavior of the Wii System and therefore can cause unexpected problems if handled incorrectly.

It is recommended to install Priiloader only on a Wii with unmodified IOSs.

You agree that you install this tool at your own risk, and that the author can not be held

responsible for any damages caused by either using or installing this tool.
