I just dumped my copy and submitted it to the db. The version I have has an EXE date of 1999-05-20 instead of 1999-05-27 and different checksums.
There appear to be at least two versions of the game.
Here's a picture from google images:

Spine serial number: SCPS-45397~8
I've read that the discs inside still have serial numbers SLPS-02020 and SLPS-02021
Mine looks just like the one below, with SLPS-02020~1 on the spine.
fuzzball and p_star may I ask what your covers like like?
