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.ini should be on the sd root(only once, they get copied to NAND) and can be found here.
* save 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)
