Here is my AA code that works in game injected using CE :

Code:

[ENABLE]
alloc(newmem,512)
label(returnhere)

007XXXX9:
jmp newmem
nop
returnhere:

newmem:
and dword ptr [esp+20],7XXXXXXX
fmul dword ptr [esp+20]
mov eax,[eax]
jmp returnhere

[DISABLE]
dealloc(newmem)

007XXXX9:
fmul dword ptr [esp+20]
mov eax,[eax]

I have converted this code in C++ to inject it via a dll, but my code when it's injected makes the game crash :

Code:

#define jmp(frm, to) (int)(((int)to - (int)frm) - 5);
DWORD Address = 0x007XXXX9, AddressRet = 0x007XXXXF; // Those are correct, checked via CE
char szAddressMem[5];

void __declspec(naked) __stdcall On()
{
_asm
{
   and dword ptr [esp+0x20],0x7XXXXXXX
   fmul dword ptr [esp+0x20]
   mov eax,[eax]
   jmp dword ptr [AddressRet]
}
}

void Jump(unsigned long ulAddress, void* Function, unsigned long ulNops)
{
*(unsigned char*)ulAddress = 0xE9;
*(unsigned long*)(ulAddress + 1) = jmp(ulAddress, Function);
memset((void*)(ulAddress + 5), 0x90, ulNops);
}

void _stdcall OnOff()
{
Jump(Address, On, 1);
}

What I'm doing wrong ?

You were right !

So I added method :

Code:

void MakePageWritable(unsigned long ulAddress, unsigned long ulSize)
{
MEMORY_BASIC_INFORMATION* mbi = new MEMORY_BASIC_INFORMATION;
VirtualQuery((void*)ulAddress, mbi, ulSize);
if (mbi->Protect != PAGE_EXECUTE_READWRITE)
{
unsigned long* ulProtect = new unsigned long;
VirtualProtect((void*)ulAddress, ulSize, PAGE_EXECUTE_READWRITE, ulProtect);
delete ulProtect;
}
delete mbi;
}

Then i called the h*ck like this :

Code:

void _stdcall OnOff()
{
MakePageWritable(Address,6);
Jump(Address, PatchBoostOn, 1);
}

Given that you are hacking, why care what the protection is unless you absolutely have to change it to something specific? Just force the change no matter what.

Also, there is no reason to allocate memory to call VirtualProtect.
