TalkPlayStation.com writes:"The Playstation 3 version of Namco Bandai's fighting em up, Soul Calibur 4 doesn't support trophies. It has an in-game achievement system called required honor. Basically when you unlock something, it will pop up on the screen notifying you that you've unlocked what you've just achieved. To view the achievement you need to head over to the meseum at the battle records.
Also, there is no support for custom in-game music."
