All they'll need is your serial number which is on the bottom of the cube. Plus my gamecube is way older. I bought it the day it came out. That's right 12:30am when there were 3 left. Anyways call and let me know what they say. I still think it's your disc. And I'm pretty sure that's what they'll tell you unless they know something that I don't. But hell, then again, I've taken my gamecube apart and put it back together so many times lol.
That's why I bought my new platinum cube, I didn't want to start having problems like that with my old indigo cube which I had since Dec 2001.
Come to think of it, the same thing happened to me with Zelda:WW, I cleaned the disc with a little water and it all turned out ok.
ok since i heard some gc servers are being shut down i think i am goin to say screw it, i will only have on weapon on me and i will start playin again. i always said i would be online when they finally shut the servers down and i don't plan on missing it. guess u guys will just ahve to put up with me havin disc errors every now and then 
So you're gonna be on? Yay for the plan to hold against BB!
well my hl isnt expired, i just didnt wanna lose any more weps..screw it ill just carry one :'(
