Without any warning from Nintendo, the Wii and DSi shops have been offline for the last 3 days. The first reported report of this finding came from a Twitter user named OatmealDome, who shared images of both stores showing error codes when attempting to access them.
There are questions about all of this as there is still an explanation from Nintendo and the fact that there are no issues shared on Nintendo’s network status page. The Nintendo Wii Shop was closed in January 2019. It is currently not possible to download purchases on either platform that have not already been downloaded to your system.
Nintendo is usually good at providing some level of warning in this situation and has even mentioned it in the past. The company said in an FAQ on the subject that the company would “announce specific details” once it plans to stop consumers from downloading its digital titles.
The DSi Shop closed back in September 2016 and many DSi digital titles are available on the Nintendo 3DS. That will soon change, however, as the 3DS and Wii U eShop will close their doors next March, making it impossible to buy anything whether you have money in your wallet or not.
