How to validate .tr1 files in Python

Python
def is_tr1(file_path: str) -> bool:
    """Check if file is a valid TR1 by magic bytes."""
    signature = bytes([0x01, 0x10])
    with open(file_path, "rb") as f:
        return f.read(2) == signature

How to validate .tr1 files in Node.js

Node.js
function isTR1(buffer: Buffer): boolean {
  const signature = Buffer.from([0x01, 0x10]);
  return buffer.subarray(0, 2).equals(signature);
}

How to validate .tr1 files in Go

Go
func IsTR1(data []byte) bool {
    signature := []byte{0x01, 0x10}
    if len(data) < 2 {
        return false
    }
    return bytes.Equal(data[:2], signature)
}
