I dont know if this game still functions online but if it does I would love to have some Wii friends lol
Here's the website https://wiimmfi.de/. It's basically a replacement server for the original ones. You could even go as far as to mod your entire Wii to restore full (online) operation. First, you need to homebrew your Wii. Assuming you have it at the moment, I suggest you begin now since Wiimmfi won't work without the homebrew channel. There are plenty of tutorials on Youtube explaining how to do that. The method I used requires an sd card for the port upfront. Next, (since you'll be using the physical disc) you'll want to install a disc patcher which basically patches your disc to connect to the Wiimmfi servers instead. The Wii can't write to discs so you'll have to boot the patcher every time you want to play any game online. You can find it here https://wii.guide/wiimmfi.html. If you have any more questions I'd be glad to help.
