Hiroshi Yamauchi
In a 1997 interview with "64Dream", Itoi stated that HAL Laboratory's Satoru Iwata joined the project. Itoi said that because of this, "the tools [they're] using to make "Cabbage" are drastically modernizing. Making those tools is the most laborious part. So it looks like that part's finishing up." Furthermore, Itoi said that they were working on the project without supervision of Nintendo's president Hiroshi Yamauchi.
