It is really easy....... step by step instructions for those of you who are still unable to copy VC games to your SD card.
1. From the main menu, click on the Wii button (bottom right)
2. A screen appears with two boxes - Data management and Wii settings. Pick Data Management
3. A new screen appears. Two more boxes. Save Data and Channels. Pick Channels
4. A tabbed screen appears.... the tabs are Wii or SD card. USE THIS PLACE TO COPY YOUR VC TITLES TO YOUR SD CARD AND DELETE THEM FROM YOUR SYSTEM MEMORY. You can also copy them from an SD card to the system memory here too.
