Ys IV was originally intended to be a trilogy, mainly developed by the companies responsible for the console ports of Ys III. Tonkin House handled the SNES episode, Hudson handled the PC Engine episode, and Sega was supposed to make a Mega Drive (or MegaCD) episode. However, Sega cancelled their edition halfway through development, and therefore this console-only experiment ended up only half-finished.
