The Entry for this Disc is here
the serial for it is written as SCPS-91004 where as it should be SCPS-10008 (at least that what it has in its exe)
you can confirm that by extracting the PSX.exe file to desktop, change it extension to txt and then open it. find the string BI and the ID will be written next to that sting. it the same method i used in the PSX renamer to find ID from the PSX.exe
Unfortunately i don't have the original copy of the original version to check that is both the version are same or not, but just to update when i compare the downloaded version of both they were same.
