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."
