As reported earlier this week, the upcoming Dragon Ball DS 2 will contain the first Famicom game for the franchise, Shenron no Nazo (The Mystery of Shenlong), as a hidden extra. The official website for the game is now proudly showcasing this information:

In addition to this, a new trailer for the game has popped up online also showcasing the Famicom game, along with plenty of other aspects of the game play. We are most excited about some traditional control being tossed into the mix, since the stylus-only attacking was one of our problems with the original.

Due out on 11 February 2010 in Japan, there is still no word on a North American release for Dragon Ball DS 2.
