This version of Flicky, released by Sega for arcades, shares the core gameplay of rescuing baby birds. The 128k version indicates a higher memory capacity than earlier versions, possibly allowing for enhanced graphics or gameplay elements compared to its 64k counterpart. System 2 refers to Sega's hardware revision.  The 315-5051 number is likely an internal Sega identifier for this specific version. It maintains the classic platforming style with its vertically scrolling levels and challenging enemy encounters.  The overall experience and objective remain true to the original Flicky concept. The game was developed and published by Sega.
