The interview mentioned in the huge Star Fox 2 info dump a few days ago has been translated from Japanese to English. Shigeru Miyamoto, Takaya Imamura, and Tsuyoshi Watanabe talk about their experiences developing Star Fox and Star Fox 2. Much of what's in the interview was already known from previous interviews, but there were a few tidbits.
The decision to include Star Fox 2 with the SNES Classic was made by the producer of the SNES Classic, not Miyamoto. It's almost as if that producer read the interview about Star Fox 2 being finished and decided "why not?"
We had known that several of the characters in Star Fox were based on the personalities or mascots of various dev team members, but apparently, Andross's character was based on Imamura's boss at the time. No idea who that might be, though.
The crazy detailed diagrams of the Arwing transformations were made for the instruction manual, not for the purpose of making toys or something.
