NES and SNES Roms

I just downloaded a couple of emulators for super nintendo and NES, however its fucking impossible to find roms for these to play on. I know nintendo has cracked down on roms being available online, but i just want to play super mario kart and tetris, and i cant be arsed running to ever pawn shop in town and paying too much money for something i'll get sick of in one day.

can anyone help me out on any sites that havent been thrashed by nintendo or any other ways to download roms?

Kazaa seems to be the best place is all you'll ever need. Perfect website for ROMS.
