TypeError: a bytes-like object is required

[ZeroX]

Yes, I believe the intended purpose of the script is to output in the YAML format so it is readable, but from your post I am guessing that even when it is working there will still be some bytes in the binary that will not be readable in an editor, even if the binary file structure is known?

The other posts did help get around my original problem, but now I get the following error:

Error:
InvalidPICFileError: Invalid magic number PRJX

I thought this error would only show if the magic number was not equal to "PRJX":

if magic != 'PRJX':
			raise InvalidPICFileError('Invalid magic number ' + magic.decode('utf-8'))

I think this might be a little bit above me, essentially what I was hoping to do was to get this working, then work on other files with known binary structures and create scripts to convert them into YAML too.
