Nintendo has released a new update for Super Smash Bros. for Wii U and 3DS.
This new update will support the upcoming Cloud, Corrin and Bayonetta amiibo and any replays prior to this new update will no longer work.
Patch-notes:
Wii U Version 1.1.7
- Cloud, Corrin, and Bayonetta amiibo (including Player 2 versions) are now supported.
