Are all discs 1.00 and you just need to not patch the game? Or are many of the newer discs with the later version of the game? I may be interested in running this, so just curious.

Disc version is 1.00, and yes to run it with the minor glitches in the game its best to run not patched, hope that helps.

Edit: Sorry to point out to those interested, I'd take a guess that the digital version is pointless to run without having a couple of things patched automatically, disc version is preferred.
