Wii games are rather expensive ranging from $60-$100 per game. You want to be careful not to damage them, making them on unplayable. Wii game discs gets scratched easily even if you are careful with them. Just normal usage of inserting them in you to your game console can scratch them.
It would be wise to make backup copies of your Wii games and put the originals away in a safe place. Blank discs are cheap these days, you can pick up a whole sleeve at your discount shopping center and backup your entire Wii collection in one afternoon. Of course to do this you will need the proper software and a DVD burner.
Until recently there was no dedicated software for making game copies. You had to try and follow the tutorials posted in the forums online. Most of them are very confusing and if you try and follow them all you get is a pile of bad game copies that don't work. There is also a lot of free software, you can download that doesn't work.
The best way to make a Wii game copies is to buy software made for the job, like game copy Pro. Out of all the software we tested, we found this one to be the most efficient and easiest to use. It is almost 1 click copy. Copy guard is no problem. The software is made to bypass it. Plus it will work on any other game system. So if you have other game consoles in your house, you can copy all of your video games and back them up.
While you're really not supposed he use it for copying DVD movies and videos, it will work for this also. If you have kids that constantly watch the same movie, you know sooner or later it's going to get damaged, why not make a backup copy and let them watch that.
Wii copy games will play exactly like the original one did, with no loss whatsoever. You do not need a mod chip or any other modification to your Wii game console. As a bonus when you join, you will have access to to unlimited Wii game downloads. I have found quite a few popular new Wii games listed.
