How do I backup Wii/GC games for Dolphin emulation?

I have a softmodded Wii with system 4.3u, and I don't feel like hunting down a specific brand/model DVD drive just to backup my Wii/GC games, when I could use the Wii instead. The problem is, most of the tutorials that I have found (googled) haven't been updated in the past 2-3 years and are riddled with either broken links, or outdated software.
