Punch-Out! (Arcade)
https://patents.google.com/patent/JPH0213798B2/en?inventor=Masahito+Hatakeyama&sort=old
Genyo Takeda, Masato Hatakeyama
- This confirms that Hatakeyama was working for Nintendo / Nintendo R&D3 as early as 1980 and this patent links him to the Punch-Out (arcade) series. Makes perfect sense since he was the lead programmer of the NES and SNES Punch Out.
He probably worked on Arm Wrestling as well.
- Shigeru Miyamoto, Takashi Tezuka - part time employee at the time worked on design (Iwata Asks), Koji Kondo worked on sound (Iwata Asks), and Takao Kozai worked on some character illustrations although he was just contracted and still officially worked for Toei?
