Yeah, the spark always pissed me off. I thought there should have been a super easy setting where the spark never came.

Yes, the controllers did have four buttons, two on each side. But they were wired the same. The bottome buttons were both the same, an the top buttons were both the same. So while it had four physical buttons, internally, it was wired only with two. Oh, and the 15 button keypad. :lol Poor doomed controllers. If they only self centered, maybe they wouldn't have had such a bad rep. Or if they were indestructable. Or best, both.
