I had no idea. I just checked and it is the later version.
Just as I suspected. Thanks for the input everyone!
In case anyone didn't know, in the original version's test mode, the third value of the second row can either be a 0, 1, 2, or 3 depending on the DIP settings, and it correlates with minimum plays required. If it is 0 or 2, then it is set to a 1 play minimum. If it is 1 or 3, then it is set to a 2 play minimum. The reason it can be 0, 1, 2, or 3 and not just 0 or 1 is because there are two switches set to it, though one of the switches is not used.
In the updated version, that previously unused switch is set to control difficulty, and its status is shown in the fourth value of the second row, pushing the original fourth value (which correlates with the score required for extra ships) over to a new fifth value. If the value is a 0, then the game is set to the easier mode (four asteroids in starting wave, killer satellites begin on first wave but start out moving much slower). If the value is 1, then the game is set to the original version difficulty (six asteroids in starting wave, killer satellites begin on second wave but start out moving much faster). The third value (minimum plays) now can only display a 0 or 1.
