1764 Portable Sound Format Audio The Portable Sound Format (PSF) is a sequencer sound file format for video game music, created by Neill Corlett. PSF files contain audio data and a sequence player. A file with the .psf or .psf1 extensions will usually be self-contained files holding both the audio library data and sequencing data. A .minipsf or .minipsf1 will hold just sequencing data, while a .psflib or .psf1lib will contain the audio library data so these must reside in the same directory where used. 1 Digital Preservation Department / The National Archives 14 Sep 2016 14 Sep 2016 fmt/959 PUID psf File extension psf1 File extension psflib File extension minipsf File extension minipsf1 File extension gsf File extension gsflib File extension minigsf File extension 1316 Portable Sound Format BOF: PSFx, where x represents one of the following values for which PSF has been adapted 4th byte: 0x01: Playstation (PSF1) 0x02: Playstation 2 (PSF2) 0x11: Sega Saturn (SSF) 0x12: Sega Dreamcast (DSF) 0x13: Sega Genesis 0x21: Nintendo 64 (USF) 0x22: GameBoy Advance (GSF) 0x23: Super NES (SNSF) 0x41: Capcom QSound (QSF) Format description: http://web.archive.org/web/20140125155137/http://wiki.neillcorlett.com/PSFFormat 1 Absolute from BOF 0 0 505346(01|02|11|12|13|21|22|23|41)
