'''This tutorial tells you how to find .zmap files using a hex editor. Of course the OoT's .zmap locations are already mapped, but MM's map offsets aren't mapped yet because MM has no Filename table.'''

----

To find your map pointer (The place that tells the offset(Address) of the map), you have to go to the scene file that belongs to the .Zmap your finding...

----

How to(example is how to find Hyrules .zmap pointer):
Hyrule zscene's filestart

To find the map pointer, just look for the '''04''', which can be found on the first or the second line of your scene (All indoor maps uses the first line, and all outdoor maps uses the second line).
In this case, it's the second line, as you can see here With the '''bold''' text:

0x00: 1800 0000 0200 0068 1502 0000 0000 0002
0x10: '''04'''01 0000 0200 '''''0040''''' 1900 0000 0000 0000
0x20: 0300 0000 0200 8464 0600 0000 0200 01C0
0x30: 0701 0000 0000 0002 0D00 0000 0200 0400
0x40: 0280 1000 0281 6230 654F 84CD 4F0D 4D28

Now, the value that reveals the location of the .zmap pointer is ALWAYS 4 bytes after the "04"
like here, it says "0040"(also '''bold'''):

0x10: '''04'''01 0000 0200 00'''40''' 1900 0000 0000 0000
That means that you can find the map's offset at 0x40.

And at 0040, we can see:
0x40: 0280 1000 0281 6230 654F 84CD 4F0D 4D28

And the first 8 bytes on this line are the start and the end offsets for your map file.
'''02801000-02816230''' 654F 84CD 4F0D 4D28

So the .zmap offsets are 02801000-02816230.
