This is a ROM hack or fan translation of Astro Fang - Super Machine. Caution's fan translation of Astro Fang - Super Machine from 2001 (v20010704) made the previously inaccessible Japanese game more accessible to Western players. The English translation likely preserves the core gameplay while making the story and dialogue comprehensible for an English-speaking audience. The original game's elements, like the fast-paced action, remain unchanged, enhanced only by English language implementation.
