On YS3 - Wanderers from Ys of USA and Japan versions, I noticed that at the Beginning of YS3 intro after the words YS-III is fade out, while it slowly zooms in, the zooming picture was coming from the bottom left to the top right while it zooms in. The pictures will see for yourself in a difference.
