More instances at the same time ??

[ChrisSch]

hello!!

i want to open more instances of the game.
but when I open diablo again it just hangs...

someone know how to change this??
someone at blizzhackers has got it to work with that d3advanced thing.

don't know how to approach this problem.
i scanned for some values with cheatengine, but came up with nothing.
i scanned for the number of open instances already and other stuff, but im too noob
i also tried to stop it from using the sleep command, but that doesnt work too (

can anyone help ?

Your doing it wrong. Try removing the mutex check.

Your doing it wrong. Try removing the mutex check.

hi, i set a breakpoint with olly on D3's imports to CreateMutexA and CreateSemaphoreA, but they are never hit ?
I logged all calls to create / open mutex with another software and there doesnt seem to be a mutex that the game checks.

If I wait long enough the game eventually starts (it spawns a window) but nothing goes after that.

whats the name of the mutex? are you sure it is a mutex ????

thank you for your help Sychotix!!!!

[Sychotix]

No I'm not 100% sure its a mutex, but most of the time it is. Maybe you should try running the game in a debugger while another instance is open, and then trace back the call to whatever function tells you that it there is another instance shown?

[ChrisSch]

ok,
the game does not switch me back to the "already open" instance.
and it does not display a "game already open" messagebox or something like that.

its just opening extremely slowly, and lagging, the splashscreen takes about 20x the time. but it does finish on its own.

then, when the splashscreen is away, the window opens, but it doesnt draw anything and lags very hard.

the d3advanced-guy got it to work, and i already asked him ,but he does not answer.

do you have another idea ??
thank you so far

[Sychotix]

Are you sure the problem isn't your computer being terrible? Thats what it sounds like the problem is.

[ChrisSch]

i understand your reasoning, but with d3advanced.net I can have 4 instances open at the same with with no problem at all.
all of the instances work perfectly and run at full speed!!!

so it is possible to hack this, and make it work.
i just don't know how, i ruled out mutexes and semaphores and "sleep"

any idea?

[Sychotix]

No idea. You are going to have to figure it out on your own as I do not currently own D3. A less interesting way would be to attempt to rip the address from their software.

[ChrisSch]

yeah, i know.
i thought about it, but iam more interested about the **** they found it, and what is preventing the game from opening correctly...

thanks for your help, ill try at blizzhackers again....

If you wait long enough the game will launch.. but you will never be able to join a game..
Open the 2nd application in CE or Olly.. When its "loading" hit break, and you will end up at the mutex check.

Please tell me how it works out for you

[ChrisSch]

there is no mutex check as far as i can see
it just somehow takes longer to load.

if there would be a mutex check
the game wouldn't start at all
not just delayed...

There is a simple check (mutex?) in the launcher. If you start d3 with "-launch" to directly get into the game, it will not be able to open the (locked) mpq files. See d3debug.txt (as mentioned by somebody else...) This is why it takes so long.

i didn´t look into it yet. but take a look at the log. i think it might point you in the right direction.


or do it the dirty way: make a copy of the d3 folder. launch the second instance from there using "-launch"

Mutex checks don't have to be before the game launches, what the guy said still could apply. Also, what KOS said also sounds logical.

[ChrisSch]

I successfully blocked the creation of ".lock" files, but the second game is still slow when starting up and doesnt work correctly
