Deadly Fingertips - Finger of Death
The Soul Eater's first spell got a name change. Though Deadly Fingertips was rather artsy of an interpretation to begin with while Finger of Death is more literal.

Jowstone - Jowston
The spelling of Jowston changed from Suikoden somewhat, though it could have gone either way since Suikoden wasn't totally consistant on it itself.
Versions: PAL / NTSC UC
Northwind - North Window
Viktor's hometown is known as Northwind in Suikoden but is called North Window in Suikoden II.
The word used is UINDOu (the u is smaller sized) and to the best of my knowledge that should mean that they're going for Window. Though I have no idea why they made it a small u.
