// in little endian, the next byte should be != 0 if it's
// the KR72 structure. Meanwhile, the KR165 structure appears
// to always have a 0 here, possibly for padding. If we find
// this 0 byte, we're gonna read it, and we're gonna use that
// information to also read the title, further down, which

// If this part doesn't work correctly, parsing KR165 areas
// will usually throw an exception on parsing the shapes
// above, because the previous prop in the loop wasn't parsed
// correctly, and the shapes have some sanity checks.
