Hey! I've got a problem i cant seem to solve. I've been searching for the past 4 hours on google, but i couldnt find anything similar to me Razz

Code:
alloc(WhatNowMinesweeper,256)

0067C8F8:
jmp WhatNowMinesweeper

WhatNowMinesweeper:
push eax
mov eax,1
mov [0067C8F8],eax

pop eax


How do i convert that into C++ Inline ASM?

Code:

#include <windows.h>
#define JMP(frm,to) (((int)to - (int)frm)-5)
DWORD Adress = 0x0067C8F8;

__declspec(naked) void myCodeCave()
{
   __asm
   {
         Adress:
         jmp WhatNowMinesweeper

         WhatNowMinesweeper :
         push eax
         mov eax, 1
         mov [Adress], eax

         pop eax

   }
}

void main()
{
   *(BYTE*)Adress = 0xe9; // defining jump opcode
   *(DWORD*)(Adress + 1) = JMP(Adress, myCodeCave);
   *(WORD*)(Adress + 5) = 0x9090;
}

BOOL APIENTRY DllMain(HINSTANCE hDll, DWORD callReason, LPVOID lpReserved) {
   if (callReason == DLL_PROCESS_ATTACH) {
      //MessageBox(NULL, L"Hooked <3 ~Mystrik", L"", MB_OK);
      CreateThread(NULL, 0, (LPTHREAD_START_ROUTINE)&main, 0, 0, 0);
   }

   return 1;
}

Doesnt seem to work. Because of these errors

Auto Assembly is different than a normal assembly.
You can't access / write to an address just by setting Address: followed by the code to execute
you already set a jump instruction in 'Adress' in your main function
remove the jmp WhatNowMinesweeper
I remember writing a very lite tutorial on converting AA scripts to C++ on this forum years ago..
you can look it up it should help you understand your problem.
