Okay so I worked it out, I was doing the byte swap on every 4-byte chunks instead of every 2-byte chunks.
def flip_byte_order_16bit(data: bytes):
if len(data) % 2 != 0:
raise ValueError(
"Data length must be a multiple of 2 bytes for 16-bit flipping."
)
flipped = bytearray()
for i in range(0, len(data), 2):
group = data[i : i + 2]
flipped.extend(group[::-1]) # Reverse the 2-byte group
return flipped
Reversing every 2 bytes works great
Hopefully might be of use to someone every coming across this!
