Atomic Boy has no solid, verifiable documentation on its developer, year, or region of origin. The name fits the tradition of 80s platform arcades that put a child protagonist through short, direct levels, a very repeated mold at the time among minor Japanese studios.
With no reliable sources to go further, it's presented as a modest catalog piece, one of the many that filled arcades without aspiring to become a name of its own in the medium.
