Ys: Ancient Ys Vanished Omen is a 1987 RPG developed by Falcom first released on the PC-88 before being ported to pretty much every platform released at the time and over the next few years. Its first port released overseas was to the Sega Master System by Sega in 1988; in the US and Europe it was sold under the name Ys: The Vanished Omens and in Japan simply as Ys (イース) (the game itself is still called Ys: Ancient Ys Vanished Omen).

It is one of the few Master System games with FM support to have the FM code completely removed in its overseas releases. Furthermore, the game takes advantage of a VDP mirroring bug that was fixed on Master System II consoles and anything based on that hardware (including the Sega Mega Drive); consequently the game will look incorrectly on these systems.

A different remake of the original Ys was later included in the 1997 compilation Falcom Classics for the Sega Saturn. Despite the fact that the original Ys was the first installment of a two-part story, its sequel (Ys II: Ancient Ys Vanished - The Final Chapter) was never ported to the Master System, or the Sega Mega Drive for that matter, although a remake of Ys II was later included in Falcom Classics II for the Sega Saturn in 1998.
