When the NES
was released, there were a list of original titles from Nintendo such as Duck Hunt, Super Mario Bros. and Metroid.
These titles came in a distinctive box that was mostly black. Plus, the cartridges themselves had a black label.
So these original games have come to be known as "black box" or "black label" games.
During this time, many cartridges had five screws holding them together. Later on, to reduce manufacturing costs, this was reduced to three screws. Yes, two tiny screws times millions of cartridges really adds up.
So my question is, did ALL of the original "Black Box" NES games come in the standard five screw format or did NES eventually start shipping them in three screw format?
My assumption is that most of the original black box games were made up until the end of NES and Nintendo started using the three screw design.
EDIT
Unfortunately, I have found more examples of Black Box games coming in three-screw cases. In fact, I bought Pinball
recently and noticed it was in a three-screw case.
