best emulator for snes sprite ripping

[Shade]

I would get SNES9X(ZSNES is optional, but I don't really know very much about it)
Step 1 - Open up the game you want to rip from.
Step 2 - Disable the Background/sprites/e.t.c. by pressing the number keys
Step 3 - Take a screenshot or PrtScr of the sprite you want
Step 4 - Open up a paint program
Step 5 - Paste you screenshot into that program.
Hope that was what you were wanting! :)
