Hey guys, if you happen to have a spare NES Zapper lying around like I did, go ahead and give this mod a try. Had I known that it would actually work, I would have taken pics during the process. It's fairly simple, you just take out the components and cut a lot of plastic. I'd say the most difficult part is getting the trigger to work. I replaced a large portion of the trigger with LEGOs. Now as you pull the trigger the LEGO construction moves back with it and brushes against the B button on the Wii remote. I kept the original spring so it moves back to its resting position after being pulled. It works beautifully. Still looking for a better way to keep the remote secured to the shell, but since I don't wear the wrist strap, I figured it was a decent harness, and so far, it is.
