In early April 2024, online play and other functionality that uses online communication will end for Nintendo 3DS* and Wii U software. This also includes online co-operative play, internet rankings, and data distribution.
We will announce a specific end date and time at a later date.
Please note that if an event occurs that would make it difficult to continue online services for Nintendo 3DS and Wii U software, we may have to discontinue services earlier than planned.
- This includes software exclusive to New Nintendo 3DS
Is this the kind of thing that RiiConnect24 was for? (just for the original Wii) Or are these online services unrelated
