Harry Potter 1 PS1 ripping dialogue help

Hi. I am trying to rip the dialogue files from the first Harry Potter PS1 game. I did try PSound but it mainly not it is not giving me much even though I was told the dialog is in the WAD files. I know it is not one wad file like it is on the disc when it is extracted there are multiple wad files. Any help is appreciated.

Here is a link to the files:
