I got banned so I cant say you the exactly locaton of the addresses but I think you can find the position from 000000 to FFFFFF, just insert this in CE.
Then search for a unknown float value.
Walk up a hill search for increased.
Walk down and search for decreased.
Do this untill you find the right one.
The X and Y Addresses are then the Addresses of Z +/- 0x4 or something like this.
To find the pointer to the other players was my big problem. Uptodate i have no solution found
