The original Japanese game is titled "Bomber King Scenario 2", which is a sequel to Bomber King (Robowarrior in the U.S.) which was developed by Hudson Soft. In International territories, the game was marketed as a Blaster Master title. The game is titled Blaster Master Boy in North America, but is titled Blaster Master Jr. in Europe.

The appearance of the stage 4 boss was altered from the Japanese release when brought overseas. This was likely done as the original design looked quite phallic.
