GameCube demo disc stuff

Hi, I'm just another random user, but i'm interested of GameCube demo discs. So all kind of demo stuff is good, footage, dumps, etc. Also, I've haerd about some E3 discs sneaking somewhere there. I'm really interested about what E3 demos you have there. I know about derekb, and I have (what I think) a dump of E3 2002 playable Super Mario Sunshine demo. So put anything you want here about the demo discs. Thanks

 

If the admins allow, I could possibly share that E3 demo of Super Mario Sunshine.

 

You dont by chance know more about that demo than the ROM leak, do you? Such as when it was handed out?
