Nintendo Controller MP3, Version 2.0

Step 4 Like a Surgeon

Begin making your cuts and drilling.
Scrape a bit of the light green protective coating off of the circuit track near each hole you drill, corresponding to each button you will use.

As an added precaution, I use the Dremel tool to make additional electrical breaks in the circuit track.
This part is a little tedious. Take your time and make it pretty.
When trimming your wire down prior to soldering, pull the wire through from the back, trim and leave just a little wire coming to the front. Strip and solder.
If you mess it up, just separate a little more ribbon cable in the back and pull a little more slack through.

Cut the ribbon cable into about 6 inch strips
Use 6 wires for the UP, LEFT, and RIGHT buttons
Use 4 wires for the "A" and "B" buttons

*If you are really motivated, you could run a 10 wire ribbon cable but I think it would be more difficult to work with than it is worth.

I don't have a Coby MP3 player, but from others I've hacked, I'd be willing to bet that one side of the buttons on the Coby are connected to a common ground, as are the buttons on the NES controller. You could use that common ground and avoid having to break all these traces... and only have to solder six wires instead of ten.

Sounds plausible. Give it a shot and let me know if it works! Good Luck!
