You load the file in the first post on your Wii with the homebrew channel and follow the dialog/prompts to dump to dsp coefficient and rom files. The homebrew app will dump them to the root of the sd card, you can upload the files from your Wii to your PC using something like ftpii or remove the sd card from your Wii, insert into your pc and copy the files to the /sys/gc directory in your Dolphin directory.
As for dumping the files with a Gamecube instead of a Wii, I'm not exactly sure how to. I think you may need Phantasy Star Online (not sure which version) and a broadband adapter for Gamecube or a USB Gecko. Dumping the files with a Gamecube is going to be more difficult than dumping them with a Wii.
