With spotlights beeing round if i put the light behind the screen wont i get streeks coming from the outer edge...
Not necessarily. You could make the screen object single sided (as is the LW default) to ensure that the light can shine through from behind it.

Gobo is a lighting term - also known as a 'cookie cutter'. It refers to a mask placed in front of a lamp to 'shape' the light that comes through it. By making a gobo with a cutout the shape and size of your screen you can mask off the light that would spill out to the other side.

The best bet you would have for a reasonable result I'd say would be to parent a large box to the Nintendo screen, and make it 100% dissolved for the animation, then pop a volumetric spotlight in there and dissolve out all the parts of the scene that won't be affected by it to help speed up the render. Then render it in a separate pass and composite in post...
