Nes controller storage with security

Here's a unique NES controller mod. The modder initially thought of just putting some flash storage in his controller like so many others. Then he got the idea to a security feature. You must first enter a code to access the memory. What code? Yes, that one. He chose the Konami code. As he notes, this may not be the wisest choice for security purposes, but it sure is cool. At least it isn’t controlling something that really would require security, like his door.
