DraStic

Ok so I have pokemon black 2. When I try to play it it just brings me to the home screen on my tablet. Isthere a way to fix this?

So I tried getting games to play on drastic, but I don't know where there located, and I was thinking you could make a small update so it scans my andriod trio stealth g2 (I don't know if the model of the tablet helps, so there it is) for ds games.
