Earth Worm Jim 3

Earth Worm Jim 3 for the NES (Dendy) is an unofficial ROM hack or pirate game that exploits the popularity of the Earthworm Jim series.

The original Earthworm Jim games were developed by Shiny Entertainment and released on the Mega Drive and SNES in 1994; there were never official versions on the NES. This product is a typical example of pirate sequels to popular games.

It is a curious find from the era of pirate cartridges.
