Might I just add that Ys III for the Genny is far superior to the Turbo version. In fact, the Genesis version is the best version of all Ys III versions.
PC-8801/PC-9801 - original version. Poor scrolling, poor graphics.
MSX - poor scrolling
NES - poor graphics and sound
SNES - poor graphics, sound and gameplay. This is the worst version.
Genesis - good graphics, good sound, faithful to the original version, best gameplay of all versions
PC Engine - poor graphics, poor gameplay, good music
PS2 - good graphics, gameplay and music
PC - Ys: The Oath in Felghana (3D remake) - good graphics, good sound, fantastic gameplay. Highly recommended.
These are just my opinions.
