For PS1 Classic the last 4 bytes give the size of the first part of the PSAR,
which also means it's the offset (DATA.PSAR file) for part 2 (string as: STARTDAT)

• PSTITLEIMG000000: Not present on all PS1 Classic and followed also by 4 bytes giving length of first part. After one .pgd part and padding, "PSISOIMG0000" + 4bytes as 00.
