I think this is an error. This game was not released for the PlayStation. Or I am wrong? I have never hear from this game for the PlayStation, and I collect Final Fantasy games for years. So I have wonder me as I have see this entry. And I have not found it on GameFAQs or hear from it somewhere.
Final Fantasy III - PlayStation - Non-U.S. Game Releases - Japan
This game will maybe release on the DS. But in the moment it is only avaible for NES I think.
