Wanting to rip sounds from a PS2 game I don't own

[Pingus!]

Did you bother to extract the ISO before doing so? It doesn't take that long for PSound to do it. Otherwise, how would you not be able to if you Don't have a physical copy on your hard drive of the files? Download the ISO, unzip it with 7-zip, and upload the extracted files, and I'll try to look into it. If you're not going to have patience in ripping, you won't get anywhere.
