PSound is a (free) program that plays sounds mainly from PlayStation® (PSone® - PSone, PSound, you see... :) and PlayStation®2 games. It can also scan files for sound data, play them, and store informations about these data in playlist files, without having to rip/copy them to your hard disk (you can still convert them to wave files, if you really want).
To know much more about PSound's features and how to use them, please read the rest of this help. Thank you, and please forgive the awkward English language you may encounter here and there.
