The MiniPSF1 format is a specialized variation of the Portable Sound Format (PSF) architecture originally developed by Neill Corlett for emulated PlayStation audio. Instead of containing full audio samples, this file stores only sequence data and executable code, referencing external library files to reduce storage requirements. Primarily utilized by video game music preservationists, this legacy format requires specialized audio players or component plugins to simulate the original console hardware.

Validation Code

How to validate .minipsf1 files in Python

Python
def is_minipsf1(file_path: str) -> bool:
    """Check if file is a valid MINIPSF1 by magic bytes."""
    signature = bytes([0x50, 0x53, 0x46])
    with open(file_path, "rb") as f:
        return f.read(3) == signature

How to validate .minipsf1 files in Node.js

Node.js
function isMINIPSF1(buffer: Buffer): boolean {
  const signature = Buffer.from([0x50, 0x53, 0x46]);
  return buffer.subarray(0, 3).equals(signature);
}
Go
func IsMINIPSF1(data []byte) bool {
    signature := []byte{0x50, 0x53, 0x46}
    if len(data) < 3 {
        return false
    }
    return bytes.Equal(data[:3], signature)
}
