Ripping Turbografx and PC Engine sprites

[TomGuycott]

I've been looking around for tutorials on ripping sprites from the first four Ys games on systems other than SNES, but unfortunately the systems are too obscure to get as much attention as SNES and I don't know if it has nearly as many resources for ripping sprites from them.

Does anyone know good emulators or tools for ripping from these? Kind of a shot in the dark, just wondering.
