Star Ocean 1 for the SNES was never officially translated in English. There is an unofficial fan translation, and in theory I could link you to the translation site because there's nothing illegal there whatsoever, but finding the game data that the translation is used with is a different story.
Star Ocean: Blue Sphere is essentially a follow up to Star Ocean 2, from what I've understood. Same "minor detail" as the first, except that as far as I'm aware, there is no fan translation available yet for SOBS.
Edit: Addendum: oh, by the way, don't concern yourself too much over the first Star Ocean. It isn't particularly good.
