Priiloader is a modified version of the officially discontinued Preloader. Preloader is a small application which places itself before the System Menu. Its main feature is to directly boot the Homebrew Channel or a file you can install from a FAT device. Preloader is also able to apply memory patches the system menu to remove limitations or other things. Warning! This homebrew makes permanent changes to your Wii’s flash memory (NAND) and should be used with caution.

Changes:

Redesigned a bit of the installer. it is now using the HW_AHBPROT flag set by HBC and no longer requires
a patched ios when run from HBC 1.0.7 or above. if it is run from < 1.0.7 then it still requires a patched IOS. NOTE : the redesigned part of the installer is closed source for now cause of the used code Booting a Dol/Title now stops the DVD drive as well Titles list is now forced to display in english Dropped Support of Cios Added support for Homebrew channel 1.0.7&1.0.8 booting & reloading (in case of a DSI crash) Added online Updating (full versions and beta versions. also language mods are available) Added a password backdoor incase you forgot the password.To change the password temporary to "BackDoor" press on the Password Screen "1" and then 4 times "2" on the Remote or "Y" and 4 times "X" on GC/Classic. Added System Menu TMD patching for HW_AHBPROT so that applications started by Priiloader can enjoy the fun too Fixed rare bug when Show Debug info was on and reset was pressed Fixed some USB stuff Fixed some title booting stuff (removed & moved to SD titles are not listed anymore) Fixed the green bar that could show when booting system menu Fixed .elf binary loading
