Nintendo Wii got a minor firmware update today. The new version is 3.3E (I think it’s U for US, J for Japan).
The mail on Wii from Nintendo said:
Save files created by unauthorised modifications may cause damage to your Wii console. This Wii Menu update will detect and automatically delete such files. Please note that these deletetion measures will not affect Wii consoles that contain only normal save files.
This update also adds a new feature to the Mii Channel. You can now move a Mii from the Mii Plaza to the Mii Parade. To do this, pick up a Mii and release it over the Mii Parade icon in the upper-right corner of the screen.
