Hirokazu Yasuhara

I was reading one of our interviews

Gamasutra: Actually, what games did you work on before Sonic? I actually don't know.

Hirokazu Yasuhara: Before Sonic, I worked on things like the arcade version of Altered Beast. After that, I worked on downloadable games [for the Mega Drive's Game Toshokan system in Japan] with Mark Cerny.

Gamasutra: Really? Which one?

Hirokazu Yasuhara: Pyramid Magic and so on. 

if it's true he worked on Altered Beast, he's either FU., TAK., MOR., TOS., KAW., SAT., UCH., HKR., HAS. or HAG... or uncredited. -Black Squirrel 12:49, 24 April 2012 (CDT)
