I'm a huge mvc2 fan and this thing really hits the nostalgia bone. Really enjoying having this in the house and playing it randomly throughout the week.
Game runs on a rechargeable battery so no wifi is needed. Seems to have a pretty long battery life. There are others available too but highly priced and i would say they have same quality too.
I feel like the handheld game is over. The screen was covered with scratches. On the on/off button there is no marking to tell you it's the on and switch. The graphic are not very good.
