How to validate .trd files in Python

Python
def is_trd(file_path: str) -> bool:
    """Check if file is a valid TRD by magic bytes."""
    signature = bytes([0x52, 0x59, 0x46, 0x46, 0x54, 0x52, 0x49, 0x44])
    with open(file_path, "rb") as f:
        return f.read(8) == signature

How to validate .trd files in Node.js

Node.js
function isTRD(buffer: Buffer): boolean {
  const signature = Buffer.from([0x52, 0x59, 0x46, 0x46, 0x54, 0x52, 0x49, 0x44]);
  return buffer.subarray(0, 8).equals(signature);
}

How to validate .trd files in Go

Go

    signature := []byte{0x52, 0x59, 0x46, 0x46, 0x54, 0x52, 0x49, 0x44}
    if len(data) < 8 {
        return false
    }
    return bytes.Equal(data[:8], signature)
}
