Simple BF2 hack source with some interesting stuff.

[Tyrano]

I wrote this some months ago, it reads each bytes at some offsets that contain the little-endian for the addresses we want to write at.

It places the bytes back in order and calculate it in to a DWORD so we can write on it. Since the offsets are out of code range, we use func VirtualProtectEx to obtain writing priviledges.

Here is the highlighted source: Source:

Or just the plain one here:

#include <windows.h>
#include <Tlhelp32.h>
#include <iostream>
#define WRITE(i,w,l) WriteProcessMemory(hProc,reinterpret_cast<LPVOID>(GameDLL + i),w,l,&dSize)

	strcpy(str, "Dibq~_7c0RV\"0Dqw0Xqs{7");

	for(int i=0;i < strlen(str);i++) {
		char enc = (char)((int)str[i] ^ key);
		//char dec = (char)((int)enc ^ key);
		//printf("char: %c (enc: %c)\n", str[i], enc);
		buf[i] = enc;
	}
	buf[strlen(str)] = 0;

    SetConsoleTitle(buf);

This is one of the better code posts i've seen. I'm waiting on my BF:Heroes beta key actually. I'll leave your link beings you're citing the source, who is yourself ironically.
