Hello, I am new to WiiU gaming system. I am a pc gamer for many years. We bought this for our girls, 6 and 8 years old, for Christmas. They have played it every day since they got it. The other day, my wife went to take the disc out of the cover and cracked it. Being a pc gamer I have many programs to copy my own discs so this doesn't happen. Is there any programs to back up these games? I know it is too late now for this one, but we replaced the game from Ebay for $50.00. I really don't want to keep doing this if they break again. Any help would be great.
