Xevious: Fardraut Saga

Players can select between two modes at the title screen: "Recon", a port of the original Xevious; and "Scramble", which is a new 16-area game with new enemies, new boss battles as well as the Andor Genesis, and four ships (Solvalou, Solgrado, Zeodalley, and Gampmission). The two modes are renamed to "Arcade" and "Fardraut" in the PC Engine version. (wiki)
