Wiiチャンネル
"Photo Channel 1.1" is an optional update to the "Photo Channel" that became available on the Wii Shop Channel on December 10, 2007. It allows users to customize the Photo Channel icon on the Wii Menu with photos from an SD Card or the Wii Message Board. It also allows playback of songs in random order. The update replaced MP3 support with support for MPEG-4 encoded audio files encoded with AAC in the .m4a extension.
