The fact that it's a double-layered disc means nothing. A double-layered disc just means
that the game that is put on it can be twice as large as a game with a single-layered
disc. Double-layered can hold up to 8GB, I think, and single-layered only 4GB.

yeah that happened to me to... whenever i started my game it said the disk could not be
read... I had to buy a new smash bros... 50$ MAN!!

two ideas
1. get a wii disk cleaner and it will show the dust on it(that happens to most people and
this stragity works)
2.have you tried any other games with the wii? if they don't work either it's probly the
wii itself. if it's the wii itself i sugest getting nintendo (i forget the phone number0
(i got this from a nintendo problums site)

Well, when i'm admiring my trophies, same thing happens to me. So uh, i usually do what
that guy says up there...
