Yamamoto-san, what kind of titles were you involved with before working on the sound for Super Metroid?
Yamamoto: I joined the company in 1987, so…
That's five years after Sakamoto-san.
Sakamoto: Yes.
Yamamoto: First, I worked on the sound for Mike Tyson's Punch-Out!! After that, I was involved with the sound for Famicom Wars and Famicom Tantei Club Part II: Ushiro ni Tatsu Shojo for the Family Computer Disk System.

What kind of titles did you work on for Super NES?
Yamamoto: Super Scope 6.
The game you play with a light gun that looks like a bazooka. (laughs)
Yamamoto: Yeah. (laughs) After that, I became involved with Super Metroid.
I see. Sakamoto-san, about when did development of Super Metroid begin?
Sakamoto: I think it was around the autumn of 1991.
That's already about one year after the release of Super Famicom in Japan. What kicked off development?
Sakamoto: It didn't start because I said I wanted to make it. My boss at the time was Makoto Kano. He has retired, so I'll use the honorific "san" with his name. Kano-san said, "Sakamoto-kun, make a Metroid game for Super NES. I'll create an environment for it, so we should do it!"
