Note: A soft-modded Wii with USB Loader GX is required to accomplish this. It is a safe idea to backup and save your purchased Wii games in case the disk breaks or the Wii is unable to read the discs.
Games can be played directly off the hard drive or you may save them onto your computer (a separate guide will be made for that). The larger the hard drive, the more games it can store at one time.
Before we get started, keep in mind that the hard drive must be formatted in order to read WBFS files. A separate guide will also be made for that.
I hope you didn't actually try shaking the Wii Remote. Instead, it would be wise to remove the batteries in the mean time to conserve their juice for actual gameplay..
Access the Display as a List option at the top of the screen; if it is your first backup, the channel may already be on the appropriate menu.
Simply repeat these steps for all the games you wish to backup. Again, it's always a good idea to do this. I've had 2 disks stopped working, but I was still able to play the games through this method.
Keep an eye out for the other guides I will put up which relate to this one. I hope this wasn't overly boring. - Jorge
