The 22 year secret of Punch-Out
Taken from a recent Iwata ask:
Tanabe: What? Really?
Wada: No one has known about that for about 22 years…
Wada: I was wondering when I would have a chance to tell people that.
Iwata: You’ve been holding that information for 22 years since the release. (laughs)
Wada: Now that I had the chance. (laughs) There are a lot of hidden elements in the NES version.
