Jackal for the NES is a home adaptation of Konami's top-down run-and-gun (drive-and-gun?) arcade game.

Specifically: An ad for the JP version uses screens from the US build. Could the game actually have been cut down for the FDS rather than expanded for the NES?
Originally released for the Famicom Disk System in Japan, the game was heavily expanded for the cartridge release in America.
- The title logo was changed, of course.
- The "2 PLAYERS B" mode was removed from the US release. This mode had one player controlling the Jeep and the other firing the weapons. Perhaps they thought it was redundant due to already having a co-op mode with two separate vehicles.
- A line break was added to the last sentence of the intro.
- "A WILD BLOODY ROSE" was changed to "A WILD JACKAL", possibly due to Nintendo's strict content policies prohibiting the use of the word "blood".
- Character portraits were changed from red to blue, with frames added around them.
- The portrait graphics themselves were slightly retouched.
- More songs were added to the US release.
- All stages were expanded horizontally from 256 pixels wide to 512 pixels wide.
- This jungle level is exclusive to the US release.
- The level opens up with a helicopter dropping off the player Jeep(s), which is also an exclusive animation.
- The water is now animated, using two frames of animation.
- The battleship boss was flipped from vertical to horizontal. The level is now a bit shorter due to this.
- A sixth turret was added to said boss.
- The final level was more than doubled in length for the US release.
- Prisoner camps were added, along with a helicopter to pick them up.
- Some jets were added to the background elements.
- The final base was changed from red to brownish.
- This game start screen was added to the US release. It's also used between levels, showing player scores, with a little Jeep driving up the map showing progress.
- These two level end screens were added to the US release. The second one appears if you complete a level without dying.
- The "WELL DONE" text appears on a separate screen in the Japanese version. It's typed out on the game screen in the US release.
- Credit for visual designer Yamamoto was removed from the US release for some reason.
- A small patch of dirt under the second guy from the left was edited.
