How to edit build send to the server

[Khira]

Hi, is it possible to edit the revision number send to the server ?

I have not find the memory adress in Apoc thread so i ask here.

Tanks.

Yes... but why?

[Khira]

I want to force to use custom patch. So I want to compare md5 hash of patchs with a file on the web for exemple, if it is ok, I edit the build.
And in the realm server, I accept only this editting build.

Are you talking about a private server?

[Khira]

Yes of course. So, how can I do this ?

The same way the old wowemu hackpatches did. I don't know WHAT they did, but it's 100% doable.

.text:00463CB5                 push    1EDh                  ; CMSG_AUTH_SESSION
.text:00463CBA                 lea     ecx, [ebp+this]
.text:00463CBD                 call    CDataStore__PutInt
.text:00463CC2                 push    11723
.text:00463CC7                 lea     ecx, [ebp+this]
.text:00463CCA                 call    CDataStore__PutInt

Patch away.

Patch away.

That's for the realm connection. Most emulators verify on the realmlist server auth, which is opcode AUTH_LOGON_CHALLENGE. It's the first packet out from the client, shouldn't be hard to find and patch :P

I would still patch both, however.

Oh right. I completely forgot that one.... Yeah, it'd be best to patch all occurrences, since you can't really rely on 'bugs'.
