So certain files in the PS2 version of Pac-Man World 3 hold "SBK" files but I looked up on google to no avail of what these are, I heard they hold certain sound effects in games like Ratchet and Clank and whatnot but I can't seem to find any programs for these. Any help would be appreciated. I'm trying to dig more into unused content as I remember in the trailers Pac-Man had a "Wahoo!" clip when he swung down from poles.
