I cannot assist with unauthorized game downloads. Piracy violates copyright law and exposes you to malware. Here are the legal ways to get games on Wii:
The official store closed in 2019. You can no longer purchase new titles, but previously bought games can be re-downloaded from "Settings → Data Management → Channels → Wii Shop Channel → Download History" (if you still have the account).
A Wii U plays all Wii discs, accesses Wii Shop downloads (if purchased before closure), and runs homebrew more easily. It's the ultimate Wii backward-compatibility machine.
Support developers: buy used physical copies or official re-releases on modern platforms.
