So the whole NES fits inside the controller With an actual NES controller wired
to it, bringing my progress to 75% done.
Here is the concept "Sketch" of it...

the bottom of the NES cart is cut off, saving some room. If I can do it, The top half may be a SNES cart, and not a NES cart. saving room ( the cart is part of the case, not the game im playing.) The game I am playing clicks in the back and sticks out that way. That was the only way I could make it so small. So basically for now, i have a NES that I can play in the car and hold in my hand. Until a week or two from now, when i order the screen.
measurements again? .5" to 1" thick. 6 1/2 in tall, and about 4.75" wide.
