Sukeban Jansi Ryuko is a beat 'em up arcade game released by Sega. The game features two different sets, one running on System 16A hardware (FD1089B 317-5021) and another on System 16B hardware (also FD1089B 317-5021), suggesting potential differences in graphics or gameplay. It's known for its distinctive style and characters, typical of Sega's arcade output of that era.  While specific gameplay details may vary between sets, the core experience likely focuses on defeating waves of enemies. The use of the same board number across different system revisions hints at Sega's internal optimization or manufacturing strategies of the time.
