So, I'm new to all this stuff and trying to get my bearings on everything. I recently came across Scuf controllers, with the paddles on the back, and decided to try it myself. I've seen a few tutorials that tell you to scrape the black off of the button pads and solder the new connectors to that. I tried that on an old, junky controller, and found that it made the existing face buttons nearly unusable. Is there another method?
I see trace diagrams discussed around here. Can I use those instead? For simply adding an A and B button, is it very complicated? Also, if there's a post / tutorial that already covers that, please let me know.
Thanks!
