(even though they kept some part of it, like 4096 being the unit).
Now that you mention that...i remebered that in a pdf with specific details of ff7 files, mentioned something about that,4096 its the length of the vector. I was thinking if that could mean also that every distance from point 0 to Axis1 or axis2 or axis3 could it be 4096 , and it is, i checked other camera axis from ff7 maps and the distances are always 4096(or 4095 sometimes).
So for example , in the Outside map:
4096 -14 -32 = 4096.148923 OK
0 3451 -1763 = 3875.25096 KO
35 1645 3697 = 4046.610804 KO (but near)
I tried with other combinations and changing signs, but its the same more or less.
i checked also the coordinates of the other map and happens the same, ,with many combinations,its like some values are missing. Could be like you say, maybe in FF9 it works different,but maybe if i could make some adjustments in some values to reach the 4096 value , maybe it works, i guess i must try that at least.
Edit: Definitely, the coordinates doesnt work in the same way as ff7
