Note on release

Since there is still a high demand for preloader and I don't really want to work on it anymore I thought it would be the best to release the source. Source is released under GNU GPL 2.

Warning

PLEASE READ THE WHOLE README BEFORE RUNNING THE INSTALLER.

THIS TOOL MODIFIES THE NORMAL BEHAVIOR OF THE WII SYSTEM AND THEREFORE CAN CAUSE UNEXPECTED PROBLEMS.

IT IS HIGHLY RECOMMENDED TO INSTALL PRELOADER ONLY ON A WII WITH UNMODIFIED IOSs!!

YOU AGREE THAT YOU INSTALL THIS TOOL ON YOUR OWN RISK, THE AUTHOR CAN NOT BE HELD

RESPONSIBLE FOR ANY DAMAGES CAUSED BY EITHER USING OR INSTALLING THIS TOOL.

Note on compiling

Code has been tested on the latest devkitPro with devkitPPC and should compile fine.

Before you can compile anything you need to place a certs.bin into the data directory.

What is Preloader and what does it do?

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 to the system menu to remove limitations or other things.

Since Preloader places itself before the System Menu any problems that would cause the System Menu to fail are not causing your whole Wii to stop working.

If autoboot is enabled and you want to access Preloader's menu simply hold RESET while powering the Wii on.

Hacks

To install additional System Menu patches, simply copy the "hacks.ini" file included with preloader into the root of your SD card. (Ensure you are using the correct hacks.ini for your Wii's region.)

Then, boot into Preloader's settings, and chose to enable or disable the patches in the Hack Settings menu.

Once applied, your patches are placed in NAND, so feel free to erase the file on your SD card.

The format for adding additional hacks, or patches, to your hacks.ini file is simple and should explain itself.

Uninstall

The simplest and safest way to remove preloader is to reinstall the System Menu using AnyRegion Changer or a WAD installer.
