That is just compiling 1. Dll you manage to make all necessary arrangements ..

Chernobyl public part of the arrangements made ​​in C#
I explained and understood, and how to use it in C++

Guys! have the solution in your eyes, it is a matter of using a little logic.

Luck!!

okay true, when i think about it now there are possibilities to combine these into 1 dll, but still it needs to be injected into every process and at least in my opinion its easier to have a little prog that is run hidden and automatically that applies the fixes on its own ;)
but okay, if most of the people want dlls thats totally fine .. less work for me :D

Example:

Spoiler:

PHP Code:

---

public void ApplyGameServerFixes(string ProcName)
        {
            Process GameProcess = null;

            bool flag = false;
            try
            {
                GameProcess = Process.GetProcessesByName(ProcName)[0];
                flag = true;
            }
            catch { }

            if (!flag)
            {
                Console.WriteLine("Could not find [{0}] process", ProcName);
                return;
            }

            //--------------------------------------------------------------------
            int AddrExHandler_1 = 0x00521765;
            int AddrExHandler_2 = 0x00521768;
            //--------------------------------------------------------------------
            byte[] Patch_ExHandler_1 = new byte[] { 0x90, 0x90 };
            byte[] Patch_ExHandler_2 = new byte[] { 0xEB };
            //-------------------------------------------------------------------- 


---

Target: ApplyGameServerFixes [SR_GameServer.exe]
Open in ollydbg, press CTRL+G and put Offset.

PHP Code:

---

            //--------------------------------------------------------------------
            int AddrExHandler_1 = 0x00521765;
            int AddrExHandler_2 = 0x00521768;
            //--------------------------------------------------------------------
            byte[] Patch_ExHandler_1 = new byte[] { 0x90, 0x90 };
            byte[] Patch_ExHandler_2 = new byte[] { 0xEB };
            //-------------------------------------------------------------------- 


---

The AddrExHandler_1 located the Offset 0x00521765 and writes the bytes { 0x90, 0x90 }; --- NOP
The AddrExHandler_2 located the Offset 0x00521768 and writes the bytes { 0xEB }; -- JMP

If you want to implement it in one .DLL you can do it in C++

Examples: Fix.cpp

PHP Code:

---

#include "Fix.h"
#include "Asm.h"
void Fixs()
{
   SetByte(0x00521765,0xEB); -- JMP
   SetNop(0x00521768,2); -- NOP
} 


---

Fix.h

PHP Code:

---

void Fixs(); 


---

Asm.cpp

PHP Code:

---

#include "Asm.h"
void SetNop(DWORD dwOffset, int Size){
    for(int n=0; n < Size; n++){
        *(BYTE*)(dwOffset+n) = 0x90;
    }
}
void SetByte(DWORD dwOffset, BYTE btValue){
    *(BYTE*)(dwOffset) = btValue;
} 


---

Asm.h

PHP Code:

---

void SetNop(DWORD dwOffset, int Size);
void SetByte(DWORD dwOffset, BYTE btValue); 


---

Have enough :)
So is that you could use what public Chernobyl.

Good Luck! :thumbup:

thank you so much

That's right buddy. and users will know to do!!

1 - Compiling the program released by Chernobyl
2 - Use OllyDbg to patch files on understanding what I said.
3 - Use DLL to repair.

The choice belongs to the community! see if they choose.

Greating! ;-)

Thanks for the fixes, even if they are old, I still found some of them usefull.

About the way to use them, I think is easier to compile the code.
Just make your own

PHP Code:

---

Main() 


---

and take care of

PHP Code:

---

CloseHandle() 


---

Good luck =)
