Please note that the steps here can and might damage your Wii! I very highly recommend you install BootMii into boot2 and back up your NAND before attempting any of the following steps. If you don’t, follow these steps then come back here once you’re done. You obviously need to have the Homebrew Channel plus a USB loader installed before you can do any of this.
Getting channels to go directly to the games, or the USB Loader is easier than you would think.
Yet having to load the Homebrew channel, then going through to your USB loader can feel cumbersome sometimes. If you followed my previous post on attaching a USB hard drive to your Wii, you now should have the convenience of loading games directly from your hard drive without ever having to worry about swapping discs.
