Question about wc3 modding

I think I had made a guide to Aleksandr Vasilevsky about it. Here it is:

Step 1

Go to the game, turn on the grid and find the city closest to the hex spot you want to find.

Step 2

Count how many hexes away that spot is from the city. This is a gamble since there are two "paths" coming out of the city and you don't know which is the right one.
Every two tiles they merge however, making your life easier if your hex spot happens to be that tile.
If it is not the merging tile though, you may have to redo the whole procedure with another city (if your spot is not in the same hex line as the city).

Step 3

Find the address of that city in the conquest file.

Step 4

Remember how many hexes away your spot was (in step 2). If it was left of the city, start counting to the left of the city's address. If it was on the right, count to the right.
Each byte represents one hexagon on the map, so the distance remains the same, you don't have to convert it.

Step 5

Find the coordinates of that tile.
If they are the right ones, you are OK; if not, repeat with another city that belongs to the tile's hex line.

If you mode on PC i have a great modding guide how to find it
