Today I had a look at the MAIN.SCM script file in each of the ISO I have. I compared the files with 2 different hashing tools, HashMyFile and GUI File Signature Widget (gfsw.exe).
Previously it was assumed that all PS2 releases used the same script, but it turns out there are at least 3 different script versions on the PS2.

I will upload the files under Resources.
