[1.11] DLL Memory Map and Tool

[Myhrginoc]

Patch 1.11 hit us out of the blue with some significant changes in how code appears in the dlls. Here is the memory map as it appears on my machine:

One big annoyance is Storm.dll, which moves from the end of the list to a place where it bumps other dlls around. I found that rebasing Storm.dll allowed all the other Blizzard modules to load at their preferred addresses. You can get the rebased Storm in our File Center. (A rebased executable is not changed in any way except for the image base and addresses affected by the relocation table.)

Another observation is the VC++ Runtime Library now is jammed into the beginning or middle of some dlls, instead of appearing reliably at the end as before. That means known game code based on previous compilations will be a poor indicator of where to look in the new version. I don't know if this is the difference between compiler settings used by different programmers, or a deliberate attempt by Blizzard to discourage code editing. But it does make creating new dll plugins more complicated.

Seeign how the txt part of the patch has been done, some incompetent has taken the place of Isolde .... and that's not for good :s

I assume most ordinal has changed too no ?

[kingpin]

I assume most ordinal has changed too no ?

They have, D2Common #10519 is no longer what we are used it is by example.

[Myhrginoc]

I remember Isolde warning us a major patch could recompile with different ordinals for the same functions. It looks like we'll need to build a cross-reference.

I bet ptGame and ptUnit are all screwed up too.

[SVR]

What ???
That's just not right

Seems like they just lost their minds. (and their compiler settings ;-)
A quick check of several ordinals, all different.

oh well boys & girls, welcome back to square 1 (.11)

EDIT: Ok Myhr, just saw you posted ahead of me ;-)

Here's the first installment to the crossref ...

10575 11061 Unload Bins (Leave game)
10576 10149 Initialize Bin Files Creation (EnterGame)
10578 10653 Create .bin from Txt
10579 Not Exported Remove bin image


10579 may still be exported, just 11061 doesnt use it. It frees the mem itself through fog.10046 (Wow, is that actually still the same? just noticed )


EDIT: AARRGGGHHHH .....

They changed local calling conventions !

The functions use arbitrary registers to pass args. This *is* wrong.

Param1 in EAX
Param2 in EDI
Param3 in EBX ???

Looks like some sort of global optimization.
Totally will hose D2Mod hook concepts.

[Joel]

smells -O2 to me ....

Ehh, what do you mean, I seem to not understand what you are refering to. (And no, I have not even downloaded the new patch yet...)

They "forgot" to fill in a number of EOLs (End of Lines)

[Vendanna]

Yup, but they also destroyed most of the chains in monstats, so unless you fixed them (like Joel already did) you will not be able to add new monsters, and probably it may be buggy.

I consider 1.10 superior to what 1.11 would give me, I was rather happy at first trying they fixed the Single player Fire enchanted bug, but alas they didn't.

[ChaosEnergy]

After conversion of my files to 1.11 I started with the DLLs, and looked for already found code edits...

hmm...ok and now, I stop the conversion...

Chaos Empire wont ever come in 1.11

See the reason...

change the port which tcp/ip multiplayer games connect on
switch -actX LvL of character
Resistance Display Limit
FindPotion Items (each 3 per act and difficulty, so 15 entries)
Crushing Blow not dependend on player amount
move Exp behaviour with lvl 25 to higher values
set PlayersX Mininum
restrict PlayersX max up to 127
Runewords in items above magic type
more skills per lvlup
loose gold only from inventory, not stash
increase carry of gold in Inventar and stash
Fix cost of gambling/read from GambleCost
more items in gamble screen
change player titles
cain always get 100gold per ident
Screen Range for party
Calculation of party exp(limit to prevent overflows)
The ancients will give max exp instead of max 1lvlup
Akara quest reward
charsi items instead of rare in unique
Ormus Ring reward instead of rare now unique
Quest 1 in act3 (potion of life)
LAM Esen Status points
Hellforge Quest Drop
Quahl-Kehk Quest reward
Malah Quest reward (resis)
Skill Amount of Quests: book of skills, den of the evil, izual
activate registe MAGIC in stores
telekinese works as in classic
inscribe /name items without anya quest
hireling items
change of superunique aura
book of lore

a long list, and after I saw this..I stopped my conversion...
but i saw i need to edit my sticky collection thread for 1.10...

[Nefarius]

Ahem, You obviously didn't look carefully, I rediscovered a bunch of things for 1.11:

> Res and Res Display caps
> Runewords in everything.
> Fixed Gamble Cost
> EXP Tables, Party-2screen radius-
> Telekinesis fix.
> Socket code re-found for 1.11. (in the original thread)
> Defense while running.
> DR cap.
> ABS cap.

* change player titles - you can still edit the titles in d2win.dll as usual.
* change of superunique aura - search for the structure I posted for 1.10.
* Hellforge Quest Drop - look for the item codes in the dll...
* FindPotion Items (each 3 per act and difficulty, so 15 entries) - as above
* Quest rewards that give runes/rings etc, search for the item codes and compare structure with 1.10.

^These are easy to find/do, I never even bothered re-discovering them.
