The other day I found a copy of 10-Yard Fight that has blue end label text instead of green. I had never encountered this version of the game before, so I went ahead and picked it up. Is this the first print version of the game, and if so, are all first print versions like this with the blue text or are some green? It has five screws in the back and no serial number.
Also, I saw in a thread here that someone found a copy of Pinball that had orange end label text instead of purple. Are there any other black label NES games that have variations on their text colors?
