[Question] Commandline?

[Thiesius]

Hello guys,
As you know, when you try to run engine without command line, you get error message. And if you try to run process with /load only (wihout launcher) you get mainentance error. Is there any way to find out, why the you can connect only with launcher?
I tried to put breakpoint to CreateProcessW inside launcher. But this is what I got:

CALL blah...

0012D280   001AF4F4  |ModuleFileName = "c:\Program Files\KalOnlineEng\engine.exe"   // No comment - obvious

blah blah....

0012D284   001AD25C  |CommandLine = ""c:\Program Files\KalOnlineEng\engine.exe" /load " // WTF? "/load" only?

0012D294   04000410  |CreationFlags = CREATE_NEW_CONSOLE|CREATE_UNICODE_ENVIRONMENT|CREATE_DEFAULT_ERROR_MODE // Nothing special

0012D29C   001AD054  |CurrentDir = "c:\Program Files\KalOnlineEng" // Obvious

0012D2A0   001B0B58  |pStartupInfo = 001B0B58   //Address of STARTUPINFO struct
0012D2A4   001B0BA4  \pProcessInfo = 001B0BA4  //Address of PROCESS_INFORMATION struct
// Are those two last parameters so important for engine to work normally?

Launcher also doesn't call WriteProcessMemory, so It cannot be written lately. I don't know, so I'm asking you for help, please.

R*A*G*E*Z*O*N*E and u will find ur Question. Under How to stop zogga hack i think

Anti Zogga doesn't solve my problem. P-Server files are little bit different than Int.

Actually I meant this: Launcher has to call CreateProcess after you hit "Start" button (obviously). So if you place breakpoint on this function, you should obtain full CommandLine.
See on image:
(Notice a stack)


But if you try to call CreateProcess with same params (Except for PROCESS_INFORMATION and STARTUPINFO) you get this error:


My launcher and engine is unpacked so I should see everything clearly.
Any ideas?

*** - you are right - the problem is that the client get a random created "key" from server and then the game starts - ask Mahatma - he has more knownlegde with it - he already tryed clientless / launching kal without updater

yap the client creates a key but that routine is crackable simply .. just check the packet tutorial of mirage online or what ever that crappy game was called where the guy does crack the md5 protection of the packtes

Alright then. Thank you guys. I will ask Mahatma about details.
