does anyone know if theres a website or something with all the background images in the super mario 64 game? i mean like the 2D art that was backdropped in the worlds, particularly the water levels and such. i googled, i really did, but its kind of an obscure request and google doesnt like it.

Doubt it.

Have you tried Tumblr?
I'm scared of using it, and it confuses the [censored] out of me, but it does contain many obscure pictures...
Just search super mario 64 backgrounds and trawl through posts....
