The Nintendo Spark is a lot like the 3DS. It has the A, B, X, Y, Start, Select, Home, L, R, ZL and ZR, as well as a D-Pad and 2 Circle Pads. It also has 2 screens, the bottom screen being a touchscreen. It also has motion controls. The 3D gauge has been removed. In addition, it now takes discs instead of cartridges, but has a slot for cartridges for backwards compatibility.
