Complete retard please help

I have been doing research on modding my wii for about 2 months now and im more confused then ever. The information is scattered in so many places and is usually in a language i could only assume is english. Could someone show me a complete retards guide to modding my wii so i can play back up wii and gamecube games on a hard drive/memory card/usb flash drive? Anything but disks please as i tend to lose them quite often. I would also like to learn how to play nintendo 64 games.

Thank you for any help that I receive and much apprecciation and mahalo
