TE2006 has been ported to Nintendo DS !
The game engine is 100% identical to the latest PC/Mac version, but the World Tour is the one of TE2004, with 150 players instead of 250, due to technical limitations, and without the Davis Cup & the Masters Cup.
The game is now waiting for Nintendo's approval, and should be hopefully released in Europe in the next few months (sorry for now, there's no release date for North America).
Here a screenshot:
