Q: Can I make my own Wii Game backups (Wii ISOs) or do I have to download them from the internet? A: It is possible to make Wii isos from your games using a modded console (wiikey chip) + tools cd that came with DVD Dumper - wii disc backup software. But a much easier and faster way to get a working backup of your Wii Games is by downloading a ready made Wii ISO from the net and using image burning software to copy it to DVD-R. All in just a couple of easy steps.
