Looks like it. I encountered this commercial yesterday after looking up some more recent Wii game commercials. I click on this thinking it’s Japan’s Epic’s Yarn commercial. Besides it looking like it was recorded with a VCR, the video looked normal. Then the gameplay footage is shown. I’m like, “what…? Kirby’s Adventure?” I’m thinking “must be an extra in Epic Yarn.” Then the old  Japanese “Nintendo” splash is shown to end the CM. I’m thinking “nah, this guy must’ve edited something.” I look up another video, and it’s true, this was the real deal: this really was the Japanese Kirby’s Adventure commercial! So that means someone at HAL looked back on this commercial and thought, “You know what, let’s make a game outta this!” I gotta admit, this is pretty cool. The only other time I’ve seen Nintendo take cues from their commercials was when they took the Chandelier Dragon from the Golden Sun US commercial and added him to the game in Golden Sun: Dark Dawn.
