I really liked it and I wonder if there's a way to use it with loadiine (or any other homebrew app) now that is dicontinued, I know that the most probable answer is no, but I got nothing to lose by asking
Currently it's my understanding that homebrew gets enabled through other apps, showing up as that online instead of Wii Street U. I'm not sure if there would be a way to dump the portion of the enabling app that directs it to a server and swap it to the server you would need. I know I can't access the user created levels on Mario Maker using Loadiine GX2 through Mii Maker.
It doesn't matter if you manage to get the Wii Street U program to launch, the actual service behind it has been shut down. It won't work at all anymore, despite how it is launched.
It is possible that someone made a homebrew server (like what they did with the Nintendo Wi-Fi Connection) but if it hasn't been done already, there's probably no way it could be done now.
