Much has been said about the two versions of Ys IV but I'll let you read Hardcore Gaming 101 as their history of it is rather complete.
I will mention that none of these games ever made it out of Japan. Fortunately, someone made an English translation patch, so head on over and grab that if you so desire.

1993 - Super Famicom (Mask Of The Sun
2005 - PS2 (Mask Of The Sun - A New Theory)
