How to download mincraft to the wii?

Minecraft isn't compatible with the Wii, unless you know how to install the homebrew channel onto your Wii

You can't.

Impossible, the Wii is lacking in power to even play it.
The Wii has been discontinued.
Minecraft will only be released on Microsoft owned platforms now anyway, the other versions will stay but it won't be on the PS5 or any Nintendo product ever. I'm sorry

Minecraft isn't on the Wii yet. :-/ (Cool concept, though.)

They don't make Minecraft for the Wii.
