Ah, you are probably right, my mistake. Unfortunately I can't edit my original comment now. I was under the impression it was a Wii U file since I downloaded it from a reddit link I found that said it was a Wii U Virtual Console title. But, doing some research it was also released for the original Wii VC at some point, so it's likely that's where the file came from.
