ik heb even een beetje rond gezocht voor je op verschillende forums, en het schijnt dat veel mensen problemen hebben met het extracten van sounds van deze game. maar, na doorzoeken kwam ik dit (engelse) antwoord tegen, hij beschrijft hoe je toch door kunt gaan na de boodschap dat het een unsurported was file is.
lees dit even als je wilt, hoop t werkt voor je, succes;
I'm also trying to find a way to extract the music from the wad files. I am 100% sure that the music is present in them, cause I can kind of partially extract it. I am hoping that someone might be able to help get past the point I am stuck at. First, download Game Extractor from watto.org. Run it, and click open archive. navigate to the PON game folder, subfolder sound, and select either NSF_EN_158.wad or NSGLOBAL_400.wad. I am unsure what each of these contain exactly. In the list that appears select any of the files that you want to extract (numbers are in kilobytes). I only chose anything over 1 megabyte. click extract files and extract selected files. Now download Awave Studio from fmjsoft.com. Run it and open one of your extracted files (located in the folder you installed Game Extractor to, subfolder extract). A box comes up saying that it is an invalid filetype. Click ok. on the next window that pops up, select the editor tab and click the button on the bottom left of the window (make sure the volume on you computer isn't too loud!). you will definitely hear the audio coming through the unbearable static. if you can't try it with another extracted file.
