Endings FAQ [Spoilers]

[Sefie1999AD]

The perfect ending is only a cutscene with in-game graphics. It's not an FMV so that's why it's not in the site Xander mentioned. I've only been able to download the perfect ending in Japanese when I've searched through file sharing programs, and read the script to see what they say in the perfect ending.

I hate to nit-pick, but you can't get the Bad Ending by losing to Shuyin. You get it by getting your party annihilated during the battle against Vegnagun's head (losing to other body parts or Shuyin doesn't trigger the ending) or by taking too long in the battle against Vegnagun's head. If one of those things happen, (SPOILER)Vegnagun's big cannon fires and Spira is destroyed. And you'll get the Game Over music.

EDIT: Just for the sake of clarity, Good Ending version 2 (choosing "It's better this way") is practically the same as the Normal Ending.
