The MINIPSF format is a specific variation of the Portable Sound Format (PSF) developed by Neill Corlett for efficient PlayStation audio emulation. It is designed to store musical sequence data while referencing external library files for instrument samples, significantly reducing storage requirements compared to self-contained archives. Although primarily associated with retro gaming communities, this specialized format remains safe to use but requires dedicated audio players or emulation plugins for proper playback.
