IIRC, Turtles in Time Re-Shelled was still sublicensed by Konami because it was a remake of an early Konami era game. Lots of game ports are outsourced to other developers anyway, so I don't see that as any different, except for the fact that Ubisoft also published it. It also didn't tie in to the 2003 TV series or the 2007 film.

You're right&mdash;the video game era designations are difficult to name.
