All of a sudden in the past 2 days my Xbox decided it won't read any games, it's weird cuz it used to, I just couldn't get onto the dashboard. I get the error "16" now when I powerup with a game in the drive. In theory whether I can boot a retail game or not, how would I get a burned copy of something (the Slayer thing) to run without having a modchip. It's obviously unsigned code so I don't see that workining w/ out a modchip. And also, IF I got an original Xbox HD that was UNLOCKED could I use it as a full replacement (just plug & play/use)?
