Back in the end of 2009, it was announced that the US would get Ys I & II Chronicles and it looks like we will be getting it very soon! It is slated for early February release of this year for the PSP.
Chronicles is actually a remake of a remake of a remake. Ys I & II was originally released in 1989 after the original releases as separate games. In 2001, Complete was born for the PC. Two years later, Eternal Story came out. And finally in 2009, Legacy was added to the list of remakes, which by the way have only been out in Japan. At least until now.
The new PSP remake will have nice, crisp graphics and sound and will remain true to the original games as well as the PC remake. So be sure to look out for Ys I & II Chronicles sometime this February!
