Just realized something, while trying to write up a stub page for Cube Tech on the wiki.
According to Cube Tech's web site, as translated by Google: "The team was founded in 2004, 2008, changed its name registered as 'Cubic Technology Limited.'" ("公司团队成立于2004年,2008更名注册为'立方科技有限公司'。")
Perhaps they were founded as Yimeike, then, and became Cube in 2008?
