While the model is capable of recreating select Mario moves, it's not as if we're looking at a one-to-one simulation. To keep things simple, the researchers only focused on two inputs, "run right" and "run right and jump". The resolution was cut down from the NES' 256×240 to a much smaller 64×48 and the output frames are a fraction of the input (producing seven generated frames from the 35 it was fed), so things are far from silky smooth
