I'm having an issue with a Nes project I'm currently building. The controller doesn't respond in certain games
. Now I can load and play Mario 3 and some others without an issue but Mario 1 and Graduis won't respnd to any control input. I've checked all of my connections and solder points and they're all fine and I've also tested these games on my other console and they work perfectly so you can see where the headache is coming from!
Any help would be greatly appreciated.
