To play any of the games I've uploaded, your xbox 360 console must be flashed with iXtreme firmware LT+. You can use the older iXtreme firmwares, but its recommended that you use the latest.
Once you download the game, you'll need a few Dual-Layer DVD discs to burn them to, and a disc drive thats capable of doing that. Most computers now come with DVD+R DL burners as a standard. Run it through ABGX 360, burn using Img-Burn, and play.
