I was getting on CoD4 for xbox just to see what was going on, and every game I got into was a modded online lobby where the host and his friends had wallhack. How is this possible?
First off, you need a jTag lol. That's the biggest thing, then, I'm not sure, but you would need to transfer the files from your xbox 360 hard drive to your computer and then find a patch, copy it over and then load up your COD4 on your 360, it can also get you banned if you have a jTag.
