I was able to get my hands on a XBOX 360 a few days ago and couldn't help but to start messing with it. For anyone who has the samsung DVD drive I found a good guide that will walk you through hacking your 360 DVD Rom firmware to play burned games. This is the easiest guide I have found. It's a little bit older version but it works very well.
