what program to use

what program will i use to edit map headear

-_- Uhm..be more clear please?

a program that could edit the icon and the number..

see this.. http://wc3campaigns.com/showthread.php?t=83231

It was said in that thread that the info you want to edit is in the map header.

Use a Hex Editor. I have never done this myself before, so I don't know exactly what you should edit. Read the file specs stickied in this forum, I think it is written there.

i used xvi32 but can't find the 0x0001

Here is the header format (fixed size = 512 bytes):
char[4]: file ID (should be "HM3W")
int: unknown
string: map name
int: map flags (these are exactly the same as the ones in the W3I file)
0x0001: 1=hide minimap in preview screens
0x0002: 1=modify ally priorities
0x0004: 1=melee map
0x0008: 1=playable map size was large and has never been reduced to medium
0x0010: 1=masked area are partially visible
0x0020: 1=fixed player setting for custom forces
0x0040: 1=use custom forces
0x0080: 1=use custom techtree
0x0100: 1=use custom abilities
0x0200: 1=use custom upgrades
0x0400: 1=map properties menu opened at least once since map creation
0x0800: 1=show water waves on cliff shores
0x1000: 1=show water waves on rolling shores
int: max number of players
followed by 00 bytes until the 512 bytes of the header are filled.

Here is the footer format (optional):
char[4]: footer sign ID (should be "NGIS" == 'sign' reversed)
byte[256]: 256 data bytes for authentification. I don't know how they are used at the moment.

It isn't necessarily 0x0001
These flags are added up and alltogether stored in the map flags int.

where can i locate the mapflags

You already posted where the map flags are to be found:


At offset 8 + StringLength(map name)

If you want to find them in the w3i file, check out the w3i specs.

after the map's name there is a 00 byte (end of the string) after that there are 4 bytes that form the int that holds the bitflags. The next 4 bytes are an integer that represents the number of players, and then a bunch of 00 until the header ends

vex sorry.. but i opened my map at xvi32 and edited the byte after the maps name into number of players.. it worked! but how can I edit in changing it to non melee type of map..

read the first part of my post

thread closed.. thank you for all your help
