Demon's Souls [BLUS30443]

I can confirm the game is working flawlessly for me at 30 FPS solid, no frame drops, no audio issues. I fixed my own problem with audio (no footsteps) - You MUST defeat Phalanx and return to the Nexus. All sounds are normal after this.

EDIT: Footsteps not present is an in-game "feature", not an issue.
