BC Kid is an awesome PC Engine port. Pretty cool Amiga platformer.
It's a bad port. Compare it with the PSX, Sharp X68000 or Mega Drive versions.
There is an unconfirmed rumor that there
exists a special NEC SuperGrafx version.
This is indeed only a rumor. They planned a SuperGrafx version, but it was never released. Only an ordinary PC Engine CD port exists.
