This version of Atomic Robo-Kid shares the same core gameplay as set 1, but may have slight differences in enemy placement, difficulty, or other game mechanics. Being a second set implies possible revisions or improvements from the first.  The game's origin remains in Japan, with the ‘Type-2’ designation likely indicating a specific hardware or software revision.  The manufacturer remains unknown. The existence of multiple sets suggests either a larger-than-anticipated success or ongoing development post-release.
