Are these cheats for real?

[Preacher]

I just saw these at gamefaqs:

All Dark Magic
Press Pause and press and hold L2. Now press square, triangle, circle, and X (2x). Play further by unpausing.

Extra Movie
Go to the main menu and type in up (2x), down, right and left.

Refill Blood
Press L2 to go into the map screen. then press up, right, square, circle, up, down, right, left. Your blood vial will be refilled.

Since I currently have no access to my PS2, can someone try these out and tell me if they're for real?

No. They're from the first Blood Omen. Most sites don't check codes submitted for accuracy, so I guess a lot of people submit anything they can think of in order to get their name in the credits.
The "extra movie" code doesn't do anything at all in either game, BTW.

Preacher needs Action Replay

Bah, I do not. I've already completed this excuse for an LoK game twice now. I was just curious about these codes.
