Galaga- Is there a difference between Midway and Namco versions?

I am trying to set my machine up according to Twin Galaxies Tournament Settings. On the back of my machine, there is a very old label that says that I need to have my 6J Dip Switch #1, 2 and 3 set to ON OFF OFF, in order to get it on Rank "D". I did this, and indeed, it is on Rank "D".

The only problem is that, according to the Galaga manual that I downloaded, in order to get to a 2 player Tournament Setting game, it requires 6J Dip Switch #1 to be OFF. I would like to be able to play a 2 player tournament settings game, in order to see the 7th digit to show up in the score on the 2up side.

I then did some internet searching, and happened upon this reference to different Galaga dip settings, and I believe I found one that matches what I'm seeing. It's listed as Namco Rev. B dip settings.

Does this mean that my game is Namco instead of Midway? Does it mean that it was made in Japan instead of North America? Does it change the game in any way, other than the irritating thing I discovered above? Is there any way that anyone knows of to play 2 player tournament settings on this machine? Replace the board? Just sell the game and buy a Midway version? Other solutions?

Thanks!
 
There are different ROM versions for the Nanco and Midway, but I don't know what the differences are other than copyright text.

What is etched into copper of the boards? Does it say Midway?

What do the ROM chip labels say (different marking from Namco and Midway) ?

Rom chip 3j has several different possible roms for that location.
 
Couldn't find a better thread to bump. I just repaired a galaga board that had the galagamk (most recent of midway version??) program roms but galagamw co-processor and sound roms which are different from other galaga. Anyone have service bulletins of changes or know the differences in sound and co-processor program roms?
According to mame
galaga = namco rev.B
galagao = namco
galagamw = midway set1
galagamk = midway set2
