Things You'll Need
Instructions
Visit softpedia to download a rawdump file. Click "Download" and on the next page it takes you to, click "Softpedia Secure Download." This will open up a prompt to ask you where you want to save the file.
Save the rawdump file to your computer in a folder that you can find easily. I suggest saving it to your desktop.
Right-click on rawdump2.0.rar, the rawdump file you downloaded, and select "Extract to rawdump2.0\" which will create a rawdump2.0 folder on your desktop.
Insert the Wii game in to the DVD burner installed on the computer. It must be a 8164b, 8163b, 8162b, or 8161b burner. Open the rawdump2.0 folder and double-click on rawdump2.0.exe.
Click "Start Dump." This process can take a few hours so allow it to run completely. A message will pop up to let you know when it is done. There will now be an ISO file in the rawdump2.0 folder that has the same name as the game you just dumped, such as "Grand Theft Auto.iso".
Open Nero. Remove the Wii game from your DVD burner and insert the blank DVD-R.
Exit the start-up dialog for Nero and click on "Recorder" and then "Burn Image". This will promp you to locate the image to burn. Browse to the rawdump folder on the desktop and select the ISO file. Click "Open" and Nero will begin the burning process. When it is completed, you will have a backup of your Wii game.
