The following procedure requires a Wii with internet access. Enter the 'Avatar' menu and begin Tag mode. On the Wii go to the Nintendo Channel and enter the DS Download Service. Select a demo and have the Wii prepare it for download. An avatar balloon popup will appear after a few minutes when the Wii is transmitting the demo. Select the balloon and use the scratch card. Then exit the transmitting demo screen and return into it. Now select another demo on the Wii and repeat the process.
