This version of Warsong for the Sega Genesis is a modified or hacked version of the original game, released in the USA. The hacks alter aspects of the game, including text and graphics, and are attributed to different individuals (D and MIJET). These modifications might change gameplay, story elements, or other features.  The connection to Langrisser suggests that the hack might be based on or influenced by this well known RPG series, resulting in a unique fan-made experience.
