What you need:
Pliers
Soldering Iron
Desoldering Iron

The RF box takes the composite signal from the NES and turns it into RF. It also takes the 9v from the external adapter and turns it into 5v. It is much too big, so we are going to take it off. If you hook up power, then you will notice that the NES does not respond to the power button; it is just constantly on. That is normal, so don't worry.

DESOLDERING
Start by desoldering the four tabs. Obviously, you won't be able to fit your desoldering iron over the whole thing, so you have to suck up as much solder as you can from the sides of the tabs.

Desolder the 5 pins.

Flip the NES board over and take off the cover of the RF box.

Find the regulator and desolder it. The regulator looks like a small black box with 3 pins and a metal tab at the top. We need the regulator to bring down the voltage of the batteries so it is safe for the NES board.

TAKING OUT THE BOARD
The RF board will be soldered to the metal walls in several points. Take your pliers and break the walls away from the board. Do not worry about hurting it, we won't be needing it.

Grab your pliers and start breaking off pieces of the board. We want to take it all out so it is like picture 3.

Bend the walls until they break off the board. Using your soldering iron, take out the pins, if there are any left still in. Grab the part that is sticking out and pull, while heating the other end with your soldering iron.

You should now have all parts of the RF box taken off. Make sure you save the 7805 regulator and the heatsink that is attached to it.
