I recall you commenting on one of our posts about your son playing Splatoon 1, I really hope he's able to play soon
For the moment, you need to install custom firmware to play Splatoon 1, linking official statement since not many people have been reporting on it (even us)

That sucks, I don't moderate the Mastodon server so I can't do much about it. I don't really want to migrate 840 followers to a different server at the moment, the instance admins are really friendly and I like being in our small space.
Guess we're going to have to wait then.
Thanks for the response!
