In order to get sprites yourself, you have to download an emulator and some roms. Then while playing the rom you take screenshots of all the sprites. The only problems with this is that emulators and roms are illegal since they infringe upon the copyrights of the games' creators, since Nintendo and such only came out within thirty years ago and the copyrights expire after thirty years. That means that virtually every game still is copyrighted. Still and all, so many people do it that nobody really cares anymore. (Nintendo sure is pissed off, though) So, yeah, I think you can download ZSNES (a good Super Nintendo emulator) at www.zsnes.com, but you'll have to google search for roms. A good NES emulator is NESticle, but I don't recall what the website is. I know there's a link to it on www.i-mockery.com, just look under the hacked rom reviews.
