NES Road Runner certainly isn't a bad port, but it seems to fall just shy of being a truly great port. The main problem is the sound; effects are sparse and generic, while the music in most levels plays way too quickly. For other issues, the Road Runner is a little hard to control, and Wile E.'s movements often don't look very natural. Still, even if this isn't a truly great port, it's a good enough port. At least it doesn't make you wait between levels like the computer versions do.
