I've been looking around on YouTube for a tutorial or instructions on how to wire and build a box mod with a dna 20 chip in it, but I guess I don't know how to use the internet. Does anybody have any good links on this subject? I really want to make an NES controller mod, I've been trying to contact the guy that makes them for a while but he hasn't responded. P.S. if you're reading this I'm still interested in buying one!
