Gamnesia is reporting that the new Super Smash Bros. for Wii U has a pretty nasty bug. The error code in question is code 160-0103 and no one really knows exactly what is causing the error, but it is only showing up with this title at the present time. You can play any other title on the system with no issue. Most seem to think the error is coming from the update data.
If you receive this error, it is not advised to go into data management since that will give you error 160-1710 and this could delete all your save data or brick your console altogether. You can check out the YouTube video from Trippy12345ify that shows this in action below. Nintendo does seem to aware of this issue and hopefully they will get it fixed really soon.
