I noticed that the LED/button thingy was too thick to fit in the cartridge. I COULD have just made it fit inside somehow (in this case I could remove the button from the mini circuit board and just let the board sit inside the cart) but I decided to make a custom glowing effect.

Well, it didn't turn out to be particularly awesome at making it look like it was glowing from the inside (though maybe I could have used more LEDs) but I did get custom red lights to fit with the NES theme.

If you don't want to get into cutting wires and soldering, continue to the next step. Otherwise, continue reading.

I figured out which wires went to the little LED on the board and which ones went to the button. I never use the button, so I decided to nix it and focus on the LEDs. obviously, the red wire was carrying the positive current, and the one next to it was the ground for the LED, so it was those I separated from the rest.

I hot-glued my two LEDs in, but I moved them later when they didn't give the right effect.

The pictures are pretty self-explanatory, but basically I soldered 1. red wire to resistor, 2. resistor to positive leg of LED, 3. negative leg of LED to hookup wire, 4. wire to positive leg of second LED, 5. negative leg of second LED to another wire, and 6. other wire to ground wire.

Remember that when soldering, do NOT melt the solder directly with the iron, because that will result in a cold solder. You want the solder to melt onto the wires, so heat up the wires until you see a little smoke, then touch the solder to the wires and it will flow onto them.
