http://wii.leseratte10.de/devkitPro/Thanks @SaulFabre for re-posting this tutorial! My previous searches on the vWii SNEEK kept pointing to the original dead link.
So I've installed devkitPro, but how exactly do I install devkitARM r32? I've downloaded the linked .rar file but there's no installer that I can see. Or does "installing" in this case refer to the next step reading "restart your computer. Open C:\devkitPro\"??
