I mean it only makes sense itd count AI heroes only, otherwise itd be some inverse difficulty scaling that limits the AI more when the player is doing better (approximately). Its clearly a way to contain the AI. Btw, you dont happen to know the addresses of these limits in the code?
Edit: Found it. The limit of heroes per AI player (5 difficulties) starts at 260518, followed immediately by limits for total between all AI players (also 5) at 26052C.
Also, you mention mistranslation, I am curious, is fizmig sourced from other languages as well?

So, this -

AI player does not hire new heroes if there are 9 or more heroes on the map (including the heroes of other players)

I believe, yes.
As for AI choices you asked, look at 524B70h. You may notice some 'magic numbers' in instructions (like mov eax, 66666667h or mov eax, 51EB851Fh). They are for optimized division.

Well these are hard to comprehend, Im gonna need some time to study them more.
In another thread you indicate another memory location: "sub_52C0B0", what is that about?
Also, I am sure this must have popped up before but I cant seem to find an answer to this: is there an easy way to disable a creature upgrade (both the unit and the building)? I am toying with the idea of removing skeleton warriors.

It's the function AI_choose_secondary_skill() which calls the mentioned earlier get_skill_value().

You can alter gTownEligibleBuildMask at 697740h. But it is filled in runtime, so it will be impossible in hex (at least, directy). And try to remove Skeleton's upgrade in the function GetMonsterUpgrade() at 47AAD0h.

No, switch jmp at 524C12h, and the cases for each skill start at 525184h (4 bytes for each, ending with First Aid at 52515Bh).

Is that last address correct? It seems to be before the one for start? Or am I reading it wrong?

The table itself is at 525184h and it contains addresses for the switch jmp. So, the address containing the code for First Aid is at 52515Bh.

I am struggling to read this, so up until 125184 it sets up by calculating all the coefficients etc then this section just puts the relevant ones together for each skill? But there dont seem to be enough formulas here? And I was expecting some of them to repeat themselves?
Edit: Looking at the formula for First Aid though, it seems clear that the developers believed an AI value of 250 will be enough to pass the test. I do not know what kind of value range the_strongest_spell_efficiency_delta function takes but Artillery is 10*Attack skill, and the AI clearly does take it sometimes (I think?). So setting whatever skill you consider "must have" to something like 500 or 1000 should be enough for it to be selected? Or another value can be found based on one of the skills with a "(1000 + Army_Power) * 1/x" formula, just find one that gets consistently selected by AI and estimate early-to-mid AI army size. The question is, where exactly in the code does this number then go. My understanding of the syntax of these functions has unfortunately not progressed..

I was asked to locate the code for determining how often might.magic heroes are offered Wisdom and Magic kills to fix the bug where Elementalists are treated as a might hero in this regard. Figured it'd be worth posting here:
4DAFE4~F ; ELEMENTALIST FIX
8B F0 mov esi,eax ; ESI = hero class
D1 F8 sar eax,1 ; EAX (hero class) / 2 (dropping remainder)
01 C0 add eax,eax ; EAX * 2
39 F0 cmp eax,esi ; Does EAX = ESI?
75 2A jne 4DB018 ; if yes (magic class) -> [magic class]
EB 1C jmp 4DB00C ; -> [might class] (4DAFF0~B00B is free)

Hey BTB
Can the hill fort be easily made to charge resources as well?
edit:
What happens if you designate a spell level6?
It won't show up anywhere lvl6 is called, but if you make eg. pyramids give lvl6 spells will it work flawlessly?

I mean, it does already, so I'm assuming you mean extra resources. It's doable, but you're going to have to be more specific about what it is you're after

Never tried it, but there's one way to find out I suppose.

Currently it only charges gold, the "new hill fort" in hota does however.
If I knew how to find things in the dll I would just change the new one to lvl 1-7 from 1-5. 
I'm going to try lvl.6 spells.. because I think 1-2 is too few for non-wisdom.. which shouldn't be essential for might heroes.
Also, I would add back in dimension door and town portal which are too powerful for lvl5  and so are summon spells, except a summon undead which could be lvl5

@BTB
Not sure you have this updated in your notes but the txt file still reads:
(spell flag) BIT 3 (04) Has duration
I believe this should rather read: "Recieves duration bonus from artifacts"
For anyone interested, I believe this is the flag to add for a 50+ turn Fire Wall.

Ive seen speculation about this flag being responsible for the 1 SP = 1 turn duration property (and even hoped to use that for my own purposes) and people reporting it not working. But I will admit my assertion is based entirely on the pseudocode in the .i64 file, lines 298-302 of combatManager::CastSpell function read:
if ( (spell_traits->m_flags & 4) != 0 )
{
SpellDurationBonus = hero::GetSpellDurationBonus(castingHero);
monster_power += SpellDurationBonus;
}
where GetSpellDurationBonus handles the 4 spell duration artifacts.

Yes, I am aware. I have been plotting to jump out with this value and give it a bit of a shr treatment (I am thinking to set standard duration to something like 1+SP/4 or maybe 2+SP/8) but I dont yet understand asm well enough to make sure I dont make a mess in the process (I am worried to inadvertently overrite values stored in some other registers) so for now I am just studying the whole of CastSpell and related functions.
My other goal is to route all the enchantment type spells through GetHeroSpellBonus (I want shield/protection type spell specialists) but again, I know what to do conceptually but not yet in practice.

You might want to study the code of some plugins working with spell durations.
FfuzzyLogik
and
NewSpells
The latest virtually allows you to do all the spell magic possible, including adding new spells without replacing old ones.
