Mario & Sonic at Beijing Olympic is currently the closest.

Except it's published by Nintendo in Japan.

 

 

Even so, it's not a Nintendo game, it's a Sega game. The OP said non-Nintendo, it didn't say Nintendo couldn't publish it.

So then why is it not a Nintendo game? It was dually developed by both Nintendo and Sega.
