I wonder how well the delightful little clicky d-pad from the Neo Geo Pocket would have worked for this project if he could salvage one. I still have my NGP Color and I have always loved its little "joystick." Also, battery life was INSAAAAANE on that little system at 40 hours from just a couple AA's. I think I was the only person I knew at the time rocking Metal Slug and SNK vs Capcom on the go. Good times.
