Information:
This Japanese video has previews, commercials, and other good "things" for many Super Famicom games released in the early 1990s, including Mother 2. It is hosted by a group of four people and a bat. Information about games is presented in several formats, including group discussions about the games and through a mock quiz game-show.

The Mother 2 segment is several minutes long. Shigesato Itoi talks with one of the hosts about Mother 2. Their dialogue isn't very interesting, but the video and sound of a pre-release version of Mother 2 that's playing while they're talking is very interesting.

The pictures from the video and the digital video linked to below were captured off of a cheap TV-tuner, so the quality isn't as good as it could be.
