Extracting images?

Hi,
I am wondering whether it is possible to extract the images/sprites from SNES/NES roms? If so how? I need some images so I can go back to developing my PSP game.
Thanks,
Nick

there are programs out there that show the tiles programmed into the game cartridge, but I'm not sure if there are any that allow you to save the tiles onto your hard drive. You'd have to look around, zophar.net is a good source for such things.

yeah, you press print screen when you see the desired image, paste the screen and cut out your image. :D

lol. thanks guys
