Introduction: How-To : Make a NES to SNES Adapter
This is a quick instructable showing you how to make an adapter or rewire a NES controller to work with SNES or visa versa.
Some people enjoy the feel of the SNES controller and would like it to work with their NES system so they can play Super Mario Bros 3.
Other people, like me, want to make THIS to work with my emulator
This guide will help you :)
Step 1: What You Need.
Depending on if you want to convert NES to SNES or SNES to NES or make the adapter like i did will make a difference in what you need to have, but it wont change the basic wiring that needs to be done.
you'll need SNES controller, NES controller, NES console, SNES console. Again it depends on what kind of conversion you want to make.
Step 2: How You Do It.
The reason i made an adapter was because i wanted to use my NES table with the emulator on the computer which is hooked up to my tv or projecter. I needed a way to connect a NES controller to the SNES/USB adaptor i have (shown in the first picture). This will also work the opposite way.
I took a broken SNES controller and cut off a portion of the wire (will very depending on how long you want the adapter). I also took out the controller port from a broken NES console.
I then needed to figure out which wire went to which wire, and it wasnt as simple as matching colours or pins, so i've included a chart.
All you need to do is simply wire Pin to Pin shown in the chart NOT colour to colour.
just in case the chart is confusing you need to wire.
SNES to NES
pin 1 to pin 5
pin 2 to pin 2
pin 3 to pin 3
pin 4 to pin 4
pin 7 to pin 1
Normally i would have used shrink tube over everything to give it a much cleaner look, but i needed/wanted the adapter right away and didn't have and shrink tube at the time. So i jsut used electrical tape.
This will also work by taking the controller port from an SNES and wiring it to a piece of NES cord to make a SNES to NES adapter.
one thing that i was unsure of at first was the fact that the controller cords had 5 wires in them but the ports have 7 pins. After a little research i found out that the 2 extra pins are from add-ons like the Zapper and what-not.
Step 3: SNES Controller to NES
Now, if youre wanting to make an SNES controller to work with a NES you can use the same chart.
I wouldn't make an adapter for this mod, i would just cut a chunk off of the NES cord and splice it into the SNES cord. that way you have 1 controller with the option of using it for both SNES and NES!
