@DD, that could be. I've looked at several different files now.
the subtraction from 1 holds true in all the dats I've looked at
so I'll use that as a rule till proven wrong in testing.
Going back to the other section:
9/2 8/3 7/1
I've got an idea what is going on here but I need to look at the dats some
more.
We take the left numbers first 9 8 7
then the right numbers 2 3 1
In the NavalMines.dat these numbers are reduced by 1
We read 8 7 6 1 2 0
Not sure if this is game wide yet.
