I dumped one Original Version game and 2 Greatest Hits version games of GT2 (all both disks) and they were identical to those listed in the DB as:
Gran Turismo 2 (U) (v1.1) (Disc 1) (Arcade Mode Disc) [SCUS-94455].bin
Gran Turismo 2 (U) (v1.0) (Disc 2) (Simulation Mode Disc) [SCUS-94488].bin
It seems incorrect that the Original version has a v1.0 and v1.1 disk in it. The exe dates on GT2 v1.0 and v1.1 listed in the DB are the same, so maybe the above two disks should both be either both be v1.0, or both be v1.1.
Hope all those tangled numbers make sense ![]()
