Wii GeckoOS can act alone or take advantage of his USB Gecko Nintendo Wii development adapter. One cool feature of the OS is the fact you can boot it with the homebrew channel and use it’s Region Free feature to boot other region games on your Wii.

Changes:

Multidol games work through Gecko’s game loader, rebooter is no longer required for them
To ensure games are fully functional the game loader now uses the IOS requested by the game (as a result there is no 002 error, that error is due to game loaders booting a game with the wrong IOS)
If a game requests an IOS that you don’t have, the game’s update partition will be searched for the IOS and the option to install the IOS will be given if it is found (if you have a modchip, turn off update blocking!)
It is now possible to select not to load the debugger, which increases the number of code lines allowed by Ocarina
New hooks have been added so that most (if not all) Wii games can be hooked
Rebooter will use the hook selected on the config menu to hook games
Rebooter is now compatible with preloader
The menu interface has been improved, and you can load a custom background by creating a 640×480 PNG-24 file, naming it background.png, and putting it at the root of your SD card
The menu configuration can be saved, and the saved configuration will be loaded automatically when Gecko starts
A configuration file can be created for game specific settings like hook type
New code types are supported by the code handler
GPF (gecko patch file) support
