Heroes of Might and Magic IV Cheats & Tips

Hex Values of Heroes of Might and Magic IV
==========================================
Add Hero Skills, Creatures, and Gold
v1.00.20040204 by ZaStaR


Introduction
------------
Add hero skills, creatures, and gold by changing values in the memory of the running game.

I gathered this information to create a hack that I never finished. Instead, the info's here for people who know how to use memory editing tools like MemoryHacker or WinHex that can change numbers in the game memory HOMM uses while it runs.

Just search for the hex strings in memory then change the values where appropriate.
This information applies to IV and its expansions.

Except where otherwise noted, only zeroes are fixed hex values and the non-zero's are example values that change during the game. When searching, always use the most current numbers in the live game.

gold

When there's more than once instance of this string, usually, the last one stores the value for the human player.


Creatures
---------
"0 0 0 17 0 0 0 0 0 0 0 0 0 0 0 14 46 98 0" in character
"0 0 17 0 0 0 0 0 0 0 0 0 0 0 14 46 98 0" in city

0 0 - 0 80 creatures fixed string

When a search turns up more than one instance of the string, usually the first is stores the number that is being displayed while the second one stores the real value. You want to change the real one.

Hero Stats

count-from-here

The character number changes, depending on the expansion and the scenario. It is used to keep track of the statistics that carry over to the next scenario in the campaign. Since you can really only depend on your hero's experience being consistantly there, that'll be the best search, but it will turn up other numbers as well. The correct one will be next to a section with more than 70% 0's. It will also have many blocks of "FF FF FF FF" about 12*16 bytes after the count-from-here point, representing unlearned skills.

Releative to the count-from-here
7x16 below == hero level
12x16 below == hero skills (in long integer blocks of FF FF FF FF)

SKILLS: 4 bytes a block
"FF FF FF FF" = unlearned
"0 0 0 0" = basic
"1 0 0 0" = advanced
"2 0 0 0" = expert
"3 0 0 0" = master
"4 0 0 0" = grandmaster
12x16 bytes after the count-from-here point, the 4 byte blocks start (consecutively) in this order:
tactics, combat, scouting, nobility,
life, order, death, fire
nature, offense, defense, leadership
melee, archery, resistance, pathfinding
ships, stealth, estate, mining,
diplomacy, heal, spirituality, resurrection
enchantment, wizardry, charm, occult
daemonology, necromancy, conjuration, pyromancy
sorcery, herbalism, meditation, summoning

The section of bytes right before the section of the skills' blocks contain learned skills, each bit representing a learned/unknown skill.

Although it's interesting to tweek the hero stats just to see curious combinations like making Gauldoth start as a paladin, it's not good to overdo it and make him a grandmaster at everything. Abuse it and you won't have much fun in the game.

Changing values in memory is dangerous, like an automobile. Don't drink and drive.
