I think it looks like the case but on a disc.

I glanced after I got the Error message on my wii, (Then tried again and it worked :It was like the Smash Ball Design, but with A picture of something in one part...(Mario?)

It was a white HAL logo with a couple of characters featured on it. The background was the silvery disk color. There might have been a bit of blue tossed on there. I only saw it for about 15 seconds.

Ummm, the smash ball with a silver color?...
Fudge, I really don't remember.
I really need to be more observant.

Edit: I checked,it is the smash ball, in white with the cross like symbol shiny with lots of characters from the game.

That's not a Smash Ball, that's the Smash Bros logo, from the previous two games as well.

Not that I should have to explain that to anybody...

But I did have to take my disc out a couple nights ago...we played WarioWare and Strikers hehe.
