Good luck!
Manuals may be fading away, but maybe they’ll get one last hurrah as Nintendo has uploaded a full manual to Star Fox 2; the same kind of manual we used to expect to come with each new game. It details the story, characters, controls, features, and mechanics with brand new images (some animated).
Also uploaded are design documents for the overall game design as well as ship designsfrom June 19, 1995. They’re all in Japanese, but you can get a gist of what they’re showing and describing.
