I was prompted to do a little research about a screenshot that Jawker sent in (thanks!) about a Chinese version of Apollo Justice: Ace Attorney. This was the first I’ve heard of such a thing and it wasn’t anywhere to be found on the official iQue DS page. Little side story, China just got a localized version of Super Mario 64 DS in August.
After a little more research it looks like it’s far from official. A group called Nzace.com has been working on fan translating the Phoenix Wright games into Chinese, which makes this more of a labor of love than a commercial project.
