How can I play games that I downloaded years ago?

I don't really know if this is the right subreddit to post this in, but here I go. Recently, me and a friend have broken oit my old Wii, and have been playing some games that we haven't played in forever, like SSBB or Rhythm Heaven. One of our favorite games to play together, was pokemon rumble. Pokemon Rumble is a download only however, and Nintendo shit down the Wii's internet capabilities. I was wondering, if I can find the SD card we originally downloaded it on, would we still be able to plag it?

TLDR: Is it possible to play games from the Wii shop channel, that were downloaded on to an SD card?
