Either this site or VG Museum helped get me started, but I spent the last two nights way into the late hours (3:30am one night when I had to be up for work at 4:30am) researching via Google. I eventually stumbled upon GameStaff@Wiki and I've come up with this list:
H.Akamatsu
Y.Okuda (Yasuo Okuda)
M.Takemoto (Mitsuo Takemoto)
S.Kitamoto (Shinji Kitamoto)
I.Urata
T.Fujimoto (Takeshi Fujimoto)
N.Togakushi (Noriyasu Togakushi)
K.Ogawa (Kouichi Ogawa)
Y.Sasaki (Yoshinori Sasaki)
Y.Morimoto (Yukie Morimoto)
J.Funahashi (Jun Funahashi)
H.Maezawa (Hidenori Maezawa)
I can't find anything certain for Urata or Akamatsu. The closest I've come for Urata is Isshi Urata (or Isuji Urata). For Akamatsu, it's difficult to say. If he was the director, you'd assume he was fairly old. He was also a programmer. The only Akamatsu programmer I was able to find was Hideyuki Akamatsu, who worked on Klonoa Heroes.
