Step 7Solder NES controller and naked Remote
iImage Information

So, now it's time for soldering. It's pretty easy : you solder the A/B button to the CENTER of the Play/Pause button. You have to be really careful to only solder and touch the inside metal. If any of you tin touches the outer ring of metal, there's going to be a connection and the key will always be ON or pressed down. So, again , be careful. After soldering all buttons, you'll have one wire left : Ground. This is is really tricky because you'll need to solder the wire to one of the outer metal ring of the button (all grounds are connected together). I know the metal ring is small, but if you are cautious and solder slowly, it should be OK. It took me 2-3 times to get it right. Watch out, the ground mustn't touch the inner metal circle, otherwise it will short.
You can see in the first picture how I managed to solder wires around. It's pretty messy, but hey , it works !
On the second picture, you can see how I also managed to get wires from the top to the naked remote. It's kind of tight but everything fits and the case closes perfectly.
