Maybe this belongs on the 360 Hardware Board, but I'm going to ask my question here instead.
Does it matter which model of 360 you use to play this game?
I ask this because despite having bought the game new I've always had trouble getting my xbox to read the disc for this game. Initially I chocked it up to being a problem with the disc itself, but I've already exchanged my copy for a new one a couple of times already, and even resorted to putting it through a DVD cleaner, neither option has helped.
The only other option is that my Xbox is at fault somehow. And while I'm perfectly willing to accept that, I am confused as to why. You see, I've never had any trouble with any of the other games I own or have borrowed, but for some reason KoF13 just doesn't want to spin up.
It might be your system if that's the case; I'll see if any XB players know have had any troubles like that. --- "You interfered with a well-laid plan." "Yeah, well you can stick you well-laid plan up your well-laid a**"
I hope I'm not too late to tell you this, but a dying 360 hard drive can give disc read errors for some reason. It's a pretty major engineering flaw. When it happened to me, my copy of Oblivion stopped working when other games booted up fine. I destroyed that disc trying to clean it and later voided my warranty trying to access the 360's laser. Ouch. Eventually most of my games stopped working. and I knew the game wasn't to blame.
Here's is what you can do to make sure you aren't doing anything stupid: Remove the hard drive and see if the game boots up. If it does, your hard drive is dead/dying. Yay! Way cheaper to fix than buying a new 360.
Well if my elite model ever dies, I'll have an excuse to buy a slim. One last bit of good news: windows 8 is supposed to emulate 360 as a standard feature. This next 360 is the last one you'll have to buy.
