The standard way to copy Wii games is to use a modified chip (Modchip) or modify your Wii by disassembling it and inserting a new chip. However, this is an extremely arduous process that voids the Wii warranty. It is not recommended to perform it. Read on to find out how to back up your expensive games.
Steps
Method 1 of 2: Download and copy the game

Step 1. Download software that can bypass Wii game copy protection and install it on your computer

Step 2. Insert the Wii disc that you want to copy (or specify the location of the downloaded game file) into the CD or DVD drive of your computer and press copy
The program will decode the protection of the Wii game. The data from the Wii game disc will be copied to your hard drive. This will take about 30 minutes.

Step 3. Insert a blank DVD into your computer's drive
Let the program copy the Wii game to a blank disc. Burn the disc at very low speeds (2-8X) so the Wii can read it.
Method 2 of 2: Play
Now that the game has been copied, you need a way to play it without installing modchip.

Step 1. Download and install the latest Wii Unlock Hack
It will allow you to play games that have been copied, imported, downloaded, as well as retro games and DVDs on your Nintendo Wii without modchip.
