Re: [Gc-linux-devel] Wii Kernel experiments

[Adam S. <ash...@gm...>]

Can HBC even boot Kernel ELFs? I thought that BootMii had to be used? (I had
to use BootMii when i had Whiite installed)

Also, Please post updates on your progress, I am interested in porting
Android to the Wii but dont know enough about the kernels to download and
patch them. I learn by observing mostly, :)
